Great video! I actually have a 2011 Mazda 3 and today (same color and all) had the head gasket replaced. My mechanic told me about getting it replaced a few weeks back while tuning up and I’m now looking at these problems. I’m swapping cars with my fiancé while I’m away in the military and I’m extremely grateful that I didn’t risk any of these issues. Very insightful and more people need to be aware of this!
Thank you, glad you enjoyed it.
Hey men. Why did you replace your gasket?
What was the symptoms?
Watch the video
You were great.
Yeah, and, while you're there, with the engine running, but not hot, remove the coolant cap and see if it bubbling/exhaust gases in there - another simple check to see if the head gasket is blown.
That’s correct.
If your car is boiling and you don't have any other symptoms replace the radiator cap. You'd be surprised how many people have had a head gasket replaced and it's just a faulty radiator cap.
Very true
@@macgilligan9726 Hi, assuming the scooter is water cooled? That white smoke, if it's alot and doesn't go away, is NOT a cracked exhaust pipe, that has nothing to do with the smoking. It can be one of the 3, cracked head ,cylinder block or head gasket problem. With the head gasket being the most likely cause, unless the person you bought it from ran straight water in the engine and it froze over? The smell of fuel also leads me to believe the head gasket is at fault and leaking causing low compression and unburnt fuel to escape throught the exhaust along with the white smoke. Hope this helps you some.
@@macgilligan9726 White smoke from an air cooled engine would be considered normal to me, blue smoke would indicate burning rich { carb problem } or burning oil. Without seeing the scooter and how it runs that's my guess.
Interesting. My car has started to boil which it never does. I let her warm up before I drive, and I don’t punch it so I was like “no it can’t be blown yet” so I’ll check my cap
@@macgilligan9726 check your oil level, sometimes if theres too much oil in the engine it throws alot of smoke. 2nd check your carb. 3rd could be your head gasket or engine block.
Short and to the point. Thank you
My pleasure
If I see coolant on the floor does that mean it HAS NOT got into the engine? Please advise.
No, it just means either you have a leak somewhere or the engine is overheating and boiling out on to the floor.
@@motorcarnut but if the engine is keept on overheating if loong way drive.. is it posssible the head gasket was blown or something?
I’m trying to to figure out if my wife has a blown head gasket. She has none of the symptoms except the white smoke which last only a minute or less when you start the car after it has been off for a while. I changed the oil and it doesn’t look like it’s mixed , the coolant level is fine , and it doesn’t over heat .
Could just be normal condensation, but the do make test strips you can buy that will detect exhaust gases in the coolant system which would indicate a head gasket problem or not.
Remove the thermostat, and recheck for bubbles, the oil passages maybe away from water passages, and check to see if you hear a deep bass sound from the exhaust
Hey man, hope you see this. I been having all sorts of deal with my car lately. 2020 Nissan Altima 2.5 SR AWD with 160k miles. I get timely maintenances and all. Anyways, i replaced the thermostat about 2 weeks ago because my car was getting close to overheating (i never let it get to red zone), got the thermostat changed and did a coolant flush- no overheating or near overheat since. Yesterday i started it and had a bunch of white smoke and it smelled sweet but went away after maybe 2 min. Checked my oil and caps and everything looks normal and it still drives normal. This morning when i started it i noticed a few bubbles in the resevoir tank where the hose is. Now, i will say it has had a code for the egr system and i am waiting to get the egr part tomorrow. Ive had the car looked at up and down 3 different times
Sounds like the head gasket is starting to go from what you described.
Hey. I wanted to follow up with you and let you know that the "bubbles" I saw was just coolant moving through the resevoir haha (I had someone verify). Anyways had a block test done and it turned out not to be a head gasket. No overheating or near overheat. No white smoke since that one time. The exhaust pipes are black and dirty almost like soot. Any other recommendations? I'm still having a vibrating start. No chocolate milk oil either. I just changed it. I forgot to mention I did recently get new spark plugs put in.
My 2008 Chevy Equinox LT started getting VERY hot out of nowhere a week or so after returning from the desert (which it did not overheat when I was there which is strange) and my dash lit up with a "ENGINE TOO HOT AC OFF" notification. With my radiator fans blowing loudly. At first I went to one mechanic shop that I've been taking it too and said it may be a thermostat issue or something. They spent a few days with my vehicle (for who knows what since it's my only car) and later determined it was in fact my thermostat/possibly clogged heater core. Fast forward to today I took it into another shop for another estimate and guess what? THIS mechanic said that I need to replace a head gasket. $4,500 repair cost apparently. I could buy a used car for that price wtf? I have an extended warranty for it however I doubt they wanna pay that either. There's no check engine light or anything either.
This is something that has to be seen in person and since you got 2 different answers I’d go get one more and see what they say.
I think my little civic is having the same problem,blowing smoke,I’m losing power,and I’m not finding any oil or coolant where it’s not supposed to be,I think I’m burning it too
If it looks like in my video then yes that’s not normal
Great video. Stoked that I appear to have escaped the shit realm of this problem. I have a 2004 tacoma 344k and it’s had a terrible leak from the water pump. I switched out the thermostat and housing and it got worse. The car would go from cold to hot very quickly once running. I’m assuming that’s a water pump at this point but I was worried that maybe the head had blown out. And that’s why there wasn’t enough pressure to seal up the system. Having it towed to a mechanic today. Fingers crossed. This is the first problem I’ve really ever had. Great truck. Scared to be told it’s time to move on.
Just make sure the simple things like the radiator cap and the sealing point where it sits and seals is not distorted. Just replace the cap if in doubt. The radiator is not clogged and flows properly. Another test is when the truck is cold, start it up and see if the top radiator hose gets hard fast before it gets hot, if it does the head gasket is failing and not necessarily you will see that thick white smoke.
its time to move on
Hi there, my Renault Clio Mk2 has milky residue under the oil cap but no milky residue on the dip stick.
There’s also no oil in the overflow tank.
There is blue smoke that comes out of the exhaust when driving which is probably piston rings.
How do I know what the issue is ?
A little bit of milky residue under the oil cap is probably normal condensation. Try a thicker oil change with some “stop smoke” additive.
@@motorcarnut thank you 🙏🏽
No problem
My 2009 Mazda 173k original water pump still
Just did a tune up lol original spark plugs 😂🤷♂️
Just do the oil chances
You’ll be good
Actually,maintaining the coolant system is the key to avoid head gasket failure on any vehicle. Maintaining the oil is also very important but has nothing to do with head gasket failure.
I had my radiator and my thermostat replaced on my 2007 Mazda 6i 2.3L . The car still overheats. What other part/s can I check next that will cause it to overheat?
Start with the simple things first. Check or replace the radiator cap, make sure there is no air in the coolant system. Make sure radiator fans cycle on and off. When the car is overnight cold try squeezing the top radiator hose see how it feels then start the car and wait about 2 minutes the hose should feel about the same if it’s noticeable harder then you may have a blown head gasket pumping up the coolant system.
Hey, I have a 2011 Honda Civic. My car started smoking like that right after an oil change. Does that mean the head gasket is blown and I need to replace the whole thing?
Being it was right after an oil change that seems kinda strange? Are you sure it’s white smoke? Or is it blue? I say this because if it’s blue it could related to the oil change, wrong weight, overfilled etc?
@@motorcarnut the smoke is definitely white. I did check it and it is overfilled by quite some bit. But 30 minutes after the oil changed something made a scratching noise and a big cloud of smoke was behind the car.
What I don’t like is right after the oil change this happened. Oil should not be overfilled and without being there it’s hard to know what happened, do you know what burning coolant smells like? to see if the car is burning coolant?
@@motorcarnut this is my first car and i just barely bought it. I have no idea about a lot of stuff. It did have a weird smell to it. But there’s no leaking or puddles anywhere under the car. (Not sure if that has anything to do with it.) I did check the oil and it doesn’t look like milky or anything like that. and thank you for responding I don’t have anybody else and i definitely don’t know anything about cars.
I have the same car 2010 Mazda3 2.0L, overheated and engine wouldn't start. No oil mixing with coolant in overflow or oil pan. Coolant got into the combustion chamber when removed plugs and crank shoots out water. Is the engine savable with new head gasket or too much damage should I do an engine swap?
I like to try to save the engine that's in the car before trying an unknown salvage engine. It depends on how bad it was overheated? Because these engines are all aluminum so good chance the head is warped and hopefully not the block too. If it we me, i'd take it apart and check how bad both are, if it's not salvable and the engine has to come out at least its much easier at that point on to remove it the rest of the way. This is assuming you're doing this yourself.
Car not overheating no crap under the cap but white smoke on revs
Can be burning it, meaning the head gasket is starting to go.
I got a error about cilinder 1 (ignition problem) with lots of white smoke but it doesnt seem to lower my coolant levels?
Could be a blown head gasket leaking coolant into that cylinder causing the misfire and smoke. Should be checked asap.
Your thoughts (good video) hg replaced 6 months ago therm/coolant sensor replaced a year ago . Rad replaced 2 years ago . ....garage have done relevant checks twice and all OK. Driving .......60-70mph dash lights up coolsjtvtemp high . Gear down thfn gear down again. Got it to a safer place let it cool .
Coolant exoelled from overflow over engine. Wtf us going on here ? Thanks oh and new rad cap recently
Thank you! Wow, so with all that done I would say maybe from when the head gasket blow and car overheated first time they was a crack somewhere or the mating surfaces on both the block and head weren’t completely flat or in spec?
@@motorcarnut I'm unsure tbh but they have done checks to rule out hg failure I'm assuming checks such as compression checks
@Motorcarnut usually a compression check will so issues with this .......unless they lied but they'd be risking their reputation of so . And they (from reviews etc ) take pride in their work
I don’t know what to tell you, I’m not there to check it out but you seemed to do a lot so maybe a crack somewhere? Do you smell anything out of the ordinary?
@@motorcarnut nothing unusual no just so odd I bloody Hooe not
Awesome thank you!
You're welcome!
Could you also scope through the spark plugs holes into the cylinders
To see if there is coolant in the cylinders? Yes you can.
Great video. I got a question I have a 2016 mustang and this car is blowing smoke at idle but then when I start driving it goes away and also I doesn’t always smoke at idle some times it does and sometimes doesn’t now When I does it doesn’t blow as much smoke seen in the video but it does blow enough to note that it is not normal any help would be appreciated. Thank you.
It’s possible you’re burning coolant. Sounds like when the car is cold, coolant is seeping into the cylinders. Can be a crack somewhere but most likely one of the head gaskets going. Should have the coolant system pressurized and tested for coolant in the cylinders.
Been searching the net but haven't found a solution. My car radiator fan keeps cycling on and off for few seconds (5-10 seconds) after coming to a stop from 4 kms and sometimes even cycles on and off when driving. Had replaced the water pump and remove the thermostat. Before the waterpump was leaking but new pump had been install. Any idea on what might be the problem?
I don’t know what kind of car you have but can be a faulty fan switch, start there if the car is not overheating, it’s probably over cooling. Start with the simple things first
Same issue dohc engine 16valve 😢
Yes, can happen to any water cooled engine.
Hello mister i have a coolant leaking on my system , iswiched the radiator, checked the oil george to check if there was a leaking inside the chambers but there was not, i wonder where could the leak be , i have a honda civik 2009 automatic
Could be burning it from a head gasket that’s failing
Someone put stop leak in the car and it rocked up blew the radiator. Put new radiator thermostat and coolant filler neck car drives good but overheats still every two miles and I still have no heat.. what does that mean?
I never recommend any head gasket sealers, I even made a video on that. The car probably has a head gasket problem for someone to use those sealers.
Question
If I empty my radiator and drain all the coolant and the white smoke goes away. Could that help prove that it's a coolant issue. Also, if it's not mixing with the oil, and is just being burnt in the combustion chamber like this one you showed is, would that result in a rough idle and engine rpm bogging when pressing the Gas? I also smell a burnt oil smell
I wouldn’t recommend running engine with no coolant. And yes coolant in the combustion chamber with result in misfiring
@Motorcarnut thanks for the reply! I currently redid spark plugs. Coil packs. fuel injectors. Distrubutor caps and rotors and cables for them and a mass airflow sensor. I realized that my car takes 5w 30 but saw somewhere that 0w 20 was good for my high milage car and after an oil change 1-2 weeks later it started to blow white smoke from engine bay. Blackish grey smoke out the rear and misfires and has a rough idle as a result kind of like a heavy cam rythem. After doing all the previous work I also did a oil flush and filter change to the correct oil and it still has same problem. I bought a test kit that'd like a turkey baster with blue fluid that turns green if it detects Gas in the coolant and all and that didn't turn green so I'm at a bit of a loss rn at what I could be. Edit: also I let the car warm up and it doesn't overheat at all. Doesn't seem like coolant get warm either. After warming up I took rad cap off and stuck my finger in and coolant is cold and not moving. It's suppose to be jiggling from what I've seen so not sure how that works. Especially since my Temps aren't overheating
What is the year make and model?
Thank you - very helpful!
Glad it was helpful! and thanks for the comment!
I have a peugeot 508 1.6 tdi. I drove through a puddle/more of a lake, and there was white smoke coming out of the exhaust for the next 2 hours then it only smokes when i press the gas pedal at maximum. What could that mean? I am also losing coolant after refilling
You sucked in water hopefully you didn’t blow the engine. If it clears up you didn’t if not you did.
Great video!! So although you had white smoke why did you not have any milk shake on the dip stick ?
Thank you!, good question. Because the coolant was leaking into the combustion chamber and not in any oil galleries. So there was no mixing oil with coolant.
@@motorcarnut And what is the solution in this case? My SUV has a lot of white smoke, but the dip stick is clean with only oil. I know that´s a head gasket problem. What can be the solution for my car? thanks!
Head gasket replacement if the white smoke doesn’t go away.
My car most mornings have white smoke come out the tailpipe and a coworker said it antifreeze burning meaning that it was getting into the engine and it could be blown head gasket or cracked head. I opened the oil cap and it was milky oil on the cap but not the dipstick. Inside the hole I noticed that it was milky oil on top as well. He said that it could be a vacuum leak from the intake. Need a little guidance to figure out the problem. Also other symptoms misfire on start up rough idle.
It does sound like you blew the head gasket. That would also cause misfiring.
hello man! great video, i have had my car trough service check and they said i have a faulty/blown head gasket. But i dont get any smoke and no milshake in the oil dipstick and the coolant looks kind of normal (just looks old) what whould u suggest to do
Why did they say you have a blown head gasket?
@@motorcarnut They didnt really explain why just that i needed to be replaced. Since that almost costs more then car im trying to figure out if i should add some head gasket sealer or leave it as it is. Its an older car but with only 60.000 KM (37000 miles). Would be happy to hear you suggestion.
My FJ overheated then when we filled the radiator bubbles overflowing everytime i drive the radiator hose always pops off is this a sign for blown head gasket?
Yes
@@motorcarnut i told my mechanic and he was telling me "oh its only making bubbles because we put that radiator cleaner" now when we check the oil mixed up with water. Would it get fixed if we replace the head gasket?
That don’t sound right to me.
Yes, but also have to make sure head and block are straight and not warped.
I have a 06 Dodge caravan that has been leaking coolant really bad and last Thursday I replaced water pump and the week before that I changed the radiator. I was driving yesterday and smelled wires burning and then I saw white smoke coming from the hood. Pulled over and coolant was leaking from the front. The burning wire smell is gone but inside and outside it's smells like coolant and also the engine is hissing and I saw coolant all over radiator fan. Have any idea why my van is still leaking coolant even though I have a brand new water pump and radiator?
Sounds like you blew the head gasket. Probably overheated too much before.
I have a 2004 Acura MDX. During the summer there are no codes, and the car is running fine, during the winter I get back the codes. I replaced all spark plugs and all ignition coils. Car dets to 3000RPMs while accelerating on the lower gears like 1st and second. I have codes P0300, P0306, P0302, P0301, P0304. What is that a head gasket? Or could be throttle body that in this car comes with Air mass flow sensor, and Idle air control valve built into one piece?
Sounds like a heat sensitive electrical problem. This type of problem has to be diagnosed with live data on a scan tool. Those are misfire codes so probably not a single issue like a coil or plug. Could be low fuel pressure too, crank or cam sensors or mass air flow sensor but you don’t want to just throw parts at the situation. That’s why it should be diagnosed with a scan tool.
I have a question no white smoke no milky oil but the car is running hot and I’m losing water from the reservoir but it’s not leaking out the car it gets hot at soon as it’s idled
Try simple and cheap things first. Could be a bad radiator cap.
Hello. I have a 2014 Ford Ranger. Recently replaced the thermostat, flushed the cooling system but I'm experiencing white smoke when the engine is cold. The AC doesn't warm anymore, but as soon as the engine is warm ( heat gauge more or less in the middle) the white smoke disappears.
No milky residue. Suspect it's coolant burning, but don't know if it's the head gasket that's failing, because there's no visual coolant leaks. Any advice would be appreciated?
It's normal to have some white smoke when the engine is, say overnight cold, that's just condensation, but if you know it's more than normal, try giving it a smell, if it smells a kinda sweet than you're burning coolant. Probably because when the engine is cold metal expands causing the coolant to enter the cylinders and when it heats up it seals itself. Probably a blown head gasket or a crack in the head or block but that's rare. Hope this helps.
Can white smoke come out of its cold outside than normal? Is it normal for white smoke to come out for a minute if its really cold outside than stops after a minute??
@franky-fr9ow Yes, that’s called condensation and normal
@@motorcarnut well I'm sure its not condensation because my car has thick smoke accompanied by a rattling or grinding sound coming from the hood
You left that out of you first comment? I’m not a mind reader
How much it will cost me if I repair this blown head gasket to mechanical?
What vehicle and engine do you have?
@@motorcarnut 2009 chevy malibu 2.4L
Will vary greatly but around $1500 is average.
Got a 1.4t petrol, loosing water and oil,
Oil doesn't seem in with the water and no smoke. But loosing both oil and water.
Any ideas.
Has to be a leak somewhere
Does the smoke come out everytime you start the car or sometimes
If it’s a blown head gasket, Every time.
It comes out every time I do a cold start

Sir, working on 1996 Buick Park Avenue 3.8L for a young man so he can go to school. How can you tell the difference between blown head gaskets versus cracked block. The car had been sitting for 12 months, drained the old gas, fresh plugs. It started right away and the smoke was horrible through the muffler and it was coming off the engine through the vents. I want to help, but not sure how to proceed. Thanks.
The only way to know the difference is to take it apart and inspect it. But a little history would help. Was the car stored in cold climate and left outside with the proper mix of antifreeze and water? Let’s say the car was from Canada and left outside all those years with only degraded coolant then I would say it probably froze and cracked the block but those cast iron blocks can take a lot of abuse and would of blown out a freeze out plug first. Probably a blown head gasket in my opinion.
@@motorcarnut it’s in Mississippi doesn’t freeze much here, but I’m thinking he let it overheat, low coolant. Thank you.
If that’s the case it’s probably a blown head gasket like I said before. Those engine are very strong.
@@matthewpague1750 You can try block/head gasket sealant product.
Hey man I got a 2005 GMC sierra 1500 SLT 5.3L, over the last month and half everytime I start my truck there’s a lot of white smoke and has a blue tint but smells burning sort of and I checked my oil I lost a lot 90% of it and my coolant gets very low too, I have no leaks tho I checked all around and nothing. My oil isn’t a milky color either just normal used oil and due for an oil change with in the month, so should I changed the oil out soon and Motor flush it? Then get a new head gasket? Or maybe is it possible value covers or piston rings? I need some advice here thanks
90% oil loss and no leaks? you sure? The burning smell is probably oil and or coolant burning . I always say start with the simple things first. you can try the motor flush and try cleaning the engine top and bottom so after it dries you can see if you have external leaks as well. If it still smokes then further checks are needed.
My car it struggles to turn on for like 1 second and white smoke comes out but it just comes out when I turn it on once it’s left on while running nothing comes out like it’s all normal and then I turn it off and it turns on right away what can it be
Depends if this happens when the car sits overnight or long periods of time, because if it does, could be a small coolant leak inside the cylinder that builds up over long period of time and when you go to start it, it takes that extra second or two because of that hence that white puff of some. When a car is first started in the morning thin light white smoke is condensation and normal.
o4 expedition temp guauge goes from the middle of the guage normal then drops to cold then back to normal i am losing coolant but i dont see any water or coolant on the ground truck has a rough idle but smooth as butter when i step on the gas i do have coolant coming out my tailpipe not an excessive amount. i do have a new cylinder head temp sensor and yes the truck when i shut it off i can hear coolant bubbling in the plastic resevoir if the new head tempsensor doesnt solve the issue? im ost i bought the truck abot 6 months back t ran fine ice cold no over heating i drove it every day then one evening just drove it a few miles ac shutdown truck got hot guage was normal then cold then normal i was less than a mile from home ..i got it home th next added water and it drove fine for about an hour and same thing happened
There should never be coolant coming out the tailpipe, you have a blown head gasket or a crack in the head or block but most likely a head gasket failure
I have coolant spitting out from the cap I'm assuming is the head, clutch fan is fixed waterpump is fairly new, thermostat is open, it overheats a lot faster when ac is on. When driving with it off I haven't seen it get hot
I also had the vehicle for 2 weeks and only used it 3 times fml
Yes, it sounds like either a blown head gasket or cracked cylinder head if water pump thermostat and radiator are not clogged. Also, check the radiator cap could be faulty you never know. Start with simple things first
@@motorcarnut a bad radiator cap can cause smoke in exhaust??
No, but a faulty radiator cap can cause the engine to overheat and ultimately blow the head gasket and then blow white smoke from the blown head gasket failure.
Hey I have a 97 Corolla and she has light exhaust smoke any help. It stops when I drive
Thin light clear-ish white smoke when engine is cold and it’s cold outside is normal when starting car for the first time.

The radiator block just blew out the o ring and a piece of it next to the o ring blew out as well. Changed spark plugs one day. Then changed valve cover because it was leaking onto spark plugs I believe. fixed all these things and car would run for a day then I’d go to start it and it putters and acts like it doesn’t want to start. Have to give it gas and rush it into gear to even drive it. Didnt drive it for a day then friend goes to start it and it starts right up and is able to idle when the days before that I drove it and it couldn’t idle at all without dying. Got to a red light it died. Turned corner too slow it died. Don’t know what else it could be or what to do next. Need my car bad.
What kinda of car you have? Year make model?
My Toyota Camry exhaust is smoky white when first turning on the car but it doesn't smoke once driving minus when occasionally hitting the gas after being idle at a stoplight. The low oil pressure lamp light occasionally comes on when braking at a light. The mechanic says if it's the head gasket the white smoke should be constant and it isn't. I don't know what to do.
When you first start a cold overnight vehicle there will be light thin whiteish smoke with is condensation and normal. It should be like in my video. And after hitting the gas when the engine is hot should not show signs of smoke. Low pressure problem should be checked out immediately because if it’s not a faulty sensor and in fact low oil pressure you can destroy the engine very quickly. Also bring the car to a good mechanic and have them check the coolant for traces of exhaust gasses, that will confirm a head gasket that is going or it’s something else. I can smell the exhaust and know if it’s burning coolant but I’m not there to help you.
Meant, it shouldn’t be smoking like in my video
@@motorcarnut thank you for responding. I am following a few local leads for a good mechanic now. It is smoking white like in your video when first turned on. It doesn't while driving but I'm nervous about the destroying engine quickly thing. Anyway, thanks 👍
It’s not supposed to smoke like mine in the video, even cold. It’s probably a head gasket starting to go, like it leaks very little overnight and when you first start it, it burns off what was in the cylinders and that’s why you get the smoke when cold and clears up while driving. Either way have someone honest but stay away from dealerships, they will waste your time and money.
2007 charger rt/awd white smoke from tailpipes, oil and engine light are on and it’s leaking really bad underneath whenever I try to start it up and it sounds really choppy n awful like something is misaligned I also did a coolant tank pressure gauge and there was no pressure as if all the air was escaping into some crack down below hintsw the leak, I think it’s head gasket blown/cracked pcv valve or radiator cap or a mix of the 3 please help car has been sitting for about a week now
Please get back to me please and thank you a lot
You first have to determine WHERE it's leaking from underneath the car, how can I give advise? There are just too many scenarios of what it can be. It does sound like coolant is getting into the combustion chamber. Oil light is probably on because it's not idling correct and what codes are coming up?
My car has a blown gasket but it doesn’t smoke just the milky oil is in water reservoir
Because head gasket is leaking into the coolant not the cylinders
@@motorcarnut so it still has to be replaced?
Absolutely
Hi, i have a Nissan Xterra 2009. It had some radiator problem, overheating so i just switched off the engine. Came back a few days later and the car won't start, i checked the oil and it's mixing with water. But the it won't start, what could be the problem? It just gives a jerk when firing the engine.
I also have a 05 Lexus LS430 with the same problem! But i haven't checked the oil and coolant of that vehicle.
The reason it won’t start is because not only is it mixing with the oil in the crank case, coolant is also going into the cylinders. Sounds like a head gasket problem at the minimum or a cracked cylinder head.
My first answer was for zayn Hassan
Oh same person lol sorry on the Lexus you have to first see what’s going on with the oil and coolant first before I can comment on that car
@@motorcarnut thank you so much for replying. My mechanic suggested to replace the engine because according to him the engine is totalled. Can that happen?!
What if there’s only smoke on the start up
Depends on how much? Some white thin smoke is normal
@@motorcarnut it’s just a little thick and lingers it doesn’t evaporate
What kind of vehicle is it? Does sound like it’s burning coolant when sitting for awhile
@@motorcarnut everything is normal. At least not that I notice. 2000 Toyota Avalon approx 164k miles
Best you can do is keep an eye on it and see if it gets worse. Sometimes when it's humid or damp outside it may appear the smoke lingers more but normal, as long as you not losing coolant or overheating
What caused this?
Mostly neglect of the coolant system and it’s components. Ie radiator, water pump thermostat etc.
What if it only smokes when you first start the car it blows a cloud of smoke then and it stops!.
Depends what color, if it’s blue your valve stem seals are leaking oil overnight, if it’s white you have coolant seeping into the cylinders which indicates failing head gasket or crack somewhere.
It’s only when I hit over 40 and it’s just a puff then my car is fine
Should never be thick white smoke at any time.
Hi, very informative and helpful site.....please assist......
I have a 2006 ford fiesta, 1.4i, mk5 with a Duratec engine.
Water in the water bottle boils when the vehicle runs long distance or when going over short distances, stop and go situations.The heater gauge goes passed the half way mark and fan does come on but by that time the water is already boiling.
I have done the head gasket, changed the water pump, fan and the radiator. Took of the thermostat but the wayer dtill boils.....i think that i did everything possible but my car still has the same problem, not sure what to do...any ideas, solutions guys, will appreciate your comments.rgd Doug
Did you change the radiator or expansion tank cap?
In your experience what would you say about oil in coolant bottle which is clear like new oil on a 2007 nissan note with no over heating
There is a failure somewhere. Head gasket comes to mind first. Car does not have to overheat for a gasket to fail or you have a crack in the head somewhere.
Had a dream that I was sitting in a Lamborghini truck with no mi till I woke up to smoke coming from the hood of my van, but the good thing is it didn't overheat - which was strange. Cars are like people the older they get the more one has to maintain them.
Lol, that's true
Hello, 2002 BMW X5, I do have white smoke from my exaust, on start up then it subcides. I notice last year a creaming color on my oil cap and around the cap fitting, and a little on the oil dip stick. I don't drive to often, short trips because of the age of the car. My father says BMW'S are not short trip cars and you have to drive them long distances sometimes to burn off Condensation, he said thats why I'm getting the thick white smoke, but I don't know, I don't want to take it on the highway and it breaks down on me haha. Blown casket or Condensation? Sorry for the long comment haha. BTW it does smoke while I'm driving also, its like it does it off and on.
If any vehicle isn't used for a good amount of time it will have some slight milky oil color under the oil filler cap, this is normal also when you first start a cold vehicle there will be white smoke but not thick sweet smelling smoke. So I can't say for sure since I'm not there, I would change oil and filter and flush coolant system then drive it around town get it nice and hot and check your fluid levels and go further and further with it to see if it stops smoking and radiator fans come on and off.
Sub for 35 years experience. Thank you Sir.
you're welcome!
@@motorcarnut hi. I have a citroen c4 1.4. Car runs ok, but in the coolant tank i see some very minor oil spots. I dont see any bubbling in the coolant tank.
Some water drops are going out of the exhaust even with the car warm, i tasted it but doesnt taste like coolant though.
If i let the engine warm, if i remove the coolant tank cap, the coolant level rises about 2 fingers. Is it normal?
Can a head gasket be burned if there are no bubbling in the coolant tank?
Everything you explain is normal except oil in the coolant overflow. Could be a head gasket starting to fail, probably why oil is mixing with coolant.
@@motorcarnut the engine also has, in corners, at the head gasket location, external oil leaks over the block.
I put coolant in the tank up to the neck while the engine running and warm, and i saw some coolant is getting out. Everytime the fan kicks in, coolant drops a bit and i see a big bubble, but only at that time. If i accelerate or something, no bubbles there.
I also noticed something, so i wanna ask you.
When i first start the car, from inside the car, i hear a quick water bubbling in the dash. I know i heard this only in other 2 cars with head gasket isssues..Did you notice this also?
Are there also other ways to detect a failing head gasket? maybe remove the spark plugs and see if one is cleaner? or something?
i dont wanna spend alot to replace the head gasket without being necessary.
When the coolant rises when it’s hot it’s normal and when the fan kicks in it lowers is also normal. Your coolant level should be at the high mark not to the rim in the overflow tank. But you have leaks at the head gasket that is not good. Yes you can take out all the spark plugs and see it any look different from each other. And you can pressurized each cylinder with compressed air and see if any bubbles are coming out through the overflow tank, if there is bubbles than the head gasket is most like bad. The coolant noise inside the car could be a concern but check what I said first.
@Motorcarnut, thanks for the informative video.
I've been trying to diagnose my 2013 VW Amarok TDI420. Looks like EGR has been removed/deleted. Coolant expansion tank/system is over-pressurising with a lot of bubbling occurring, smells like exhaust fumes, plus there is a black soot-like deposit on the tank walls. No white smoke out of exhaust. No 'chocolate milkshake' visible yet. No sign of diesel in coolant. Possibly the slightest trace of oil, but very hard to tell & could just be from the exhaust fumes? Already replaced expansion tank cap.
I'm thinking this means there is a head gasket crack forcing exhaust gases into the coolant lines, but not big enough to lose coolant into the cylinders, Is there anything else it could be, before I go and ask my mechanic to take a look at the head? Any suggestions really appreciated.
Also concerned about driving it to my mechanic, wondering if it's worth a tow? No apparent issues with starting, idle, etc. No temp gauge on the VW Amarok, just coolant warning light, which was flicking on and off the last time I drove it.
The EGR valve is missing probably because they are known to fail pretty often and there was a recall for that. Could of been the EGR cooler was leaking into the coolant system and pumping it up if they did remove it AND it's still pumpiing up the coolant system then It does sound like the head gasket is going because you shouldn't have soot deposits in the overflow tank at all. And the exhaust flume smell confirms that to me. Best bet is to have a good mechanic check it out who knows VW's. Honestly, being diesels have more compression then gasoline engines, unless the mechanic is within 1 mile or kilometer to drive the truck there I'd have the car towed because chances are the head is probably already damaged but may still be salvageable. Good luck
I have a car question that I told to the experienced mechanic that works at the car lot that I bought the car from. Well it’s a 2011 Jeep Cherokee and I smell a burning smell from under hood and he said don’t worry it will go away in a few days.. it’s due to a valve cover gasket replacement and they spilled oil. 3 weeks later I still smell it. Also sometimes when I crank up or when my car is idiling , white smoke comes from my tailpipe. It ran just pass the middle of the temperature gauge today but immediately cooled back down. Thanks in advance
Well the oil burning smell is not normal especially after 3 weeks they probably never replaced it. When I do valve cover gasket’s I clean the area so it doesn’t leak onto the exhaust system anywhere after the repair. A slight sign of white smoke( condensation) is normal when the vehicle is cold however not when fully warmed up and coolant gauge if accurate should not pass the middle unless in extreme conditions like towing or climbing up mountain roads.
We have a 2005 Jeep Liberty and it’s doing the same thing. White smoke out of exhaust on idle after valve/cylinder head cover gaskets were replaced. I thought it was blowing white smoke because oil was leaking from the valve cover into the exhaust, but now I’m starting to think the head gasket might be to blame. Did you ever find out what was wrong with your Jeep?
edit: there’s also smoke in the engine bay…
@@YouceffKabal what that could mean is a cracked manifold, leaking the white smoke from the bad head gasket into the engine bay.
Makes sense about the coolant now. I was wondering wtf keeps happening to my coolant when I had no leak in the line. And my car is running and idling rough as hell. Man wtf! Smh to my money pit. 🙇
Sorry to hear that, you can take out the spark plugs and see if you see coolant in the cylinders, you’ll know for sure.
Hey,
So I don't know much about cars, but my car started giving that white smoke, and someone suggested getting gasket magic.
Another thing is, sometimes when I drive, it feels like the car is losing power because the gears take long to change, and when it eventually changes to the next gear, the power is up again.
Any advise?
You may have a head gasket problem or something else, no way to know without being there. I don’t recommend any sealers but you can do anything you want. I would have a local mechanic advise more.
You left out the part where the only symptom is compression from the cylinder escapes into to radiator forcing coolant into the overflow tank
Mines doing that at the moment.
No other signs just bubbles in the radiator.
Yes you’re correct, I made another video on 2 other symptoms and it included this one.
Don't forget, usually it's a component that caused the over heating. Loke water pump, radiator, etc. Replacing gasket or engine and not the cause will only get you a second blown gasket.
Good info! This video is about identifying.
My car eats oil.. Do u think the excessive oil seaping into the seals and valve cover could cause a blown gasket?
No
Seal around pistons are worn probably burning an unholy amount of oil. I believe 2008-2011 Camrys had this problem
Hey boss, i had my radiator give out which was leaking and overheated the car. I replaced it but noticed the coolant was a cloudy blue instead of blue. I was wondering what you think i should look at next because its idling like its ok so far. Im scared to drive without completely fixing it. Its a 09 maxima
When the car is hot meaning driving it for about 10 miles or so there should be no smoke. When cold there should only be a light tint of white smoke, never blue, blue is oil burning and not thick white sweet smelling smoke either that’s burning coolant. Does the car overheat now?
@@motorcarnut hey thanks for the quick reply. At the moment it seems ok .. i got prestone radiator cleaner cycling through with water to clean any thing left out of the system. I also meant the coolant its self was that color. The coolant is usually blue but when i emptied it it was blue with some sludge
😮@@motorcarnut
Why not design a better way with gaskets
It has nothing to do with gaskets failing as much as neglect of overheating engine
Nice video! My 2011 Mini Cooper S has symptom #3... a white smoky exhaust when warmed to operating temperature.
If it doesn’t go away and smells kinda sweet then it’s burning coolant and head gasket or a crack somewhere but probably the gasket is starting to go.
white smoke doesn't always mean a blown head gasket. A bad fuel injector will also cause white smoke.
White smoke can be normal condensation but bad fuel injectors won’t create white smoke
Dear sir, what if I found oil residue on the exhaust tail pipe? Thank you
Means vehicle is burning oil either through worn valve stem seals, worn piston rings bad pcv valve etc.
@@motorcarnut thanks for the reply. I guess it"s best if I just walk away when I encounter a vehicle like that.
It’s wise if you don’t have mechanic skills or know someone who does.
@@motorcarnut thank you sir
No problem
Just found your video my rav 4 is currently in the shop as result of what was initially thought to be a blown head gasket but was cleared of milkshake mixture turns out it was the rods that are meant to keep coolant and water sealed in engine with rod 1 & 2 having lost all their tension and were just sitting in the holes
The head gasket plate is still in one piece and only very teeny tiny amount of warpage to cylinder so all my mechanic has to do is remove threading from both holes and re-tap them so the bolts fit in there with full tension
You’re talking about the head bolts that became loose? If the engine was taking apart before I’d say it was human error but if the engine was never taken apart than the head gasket did blow. You may of not got oil mixing with coolant but it did overheat hence the warpage.
@Motorcarnut ah yes the head bolts thanks for correcting me bolts 1 &2 were no longer tensioned when my mechanic check it over
Mine starts up really easy has white smoke though no oil on coolant and I just changed oil but didnt seem unusually brown. The bike sat for years so I expected the fluids to be bad
I'm sorry, but other then what I told you, I don't know what the problem would be without seeing the bike.
@@motorcarnut if you have time I can post I video of it
hey man appreciate the video, i recently had a radiator hose blown and there was water in the entire hood. i replaced it and its all okay but i recently pulled out the oil cap and there was a green residue like coolant so im not sure if my head gasket has blown as well. i cleaned the cap and checked today and there was no residue again, there is no white smoke in the exhaust, the dipstick is fine, coolant level is ok, im just worried about that residue that was in the oil cap and today my low oil pressure light came on for seconds then disappeared, thank you in advance!
No problem thanks.
How long did you drive with the blown hose or how hot did the coolant gauge get before shutting it off? There should not be any coolant in the oil like you know already. A little condensation under the oil cap is normal but not green as that’s coolant.
@@motorcarnut hey man sorry to bother, my coolant leaks to the floor now, head gasket already replaced, water pump replaced, no hose cracks or reservoir cracks, keeps dropping out from the bottom, a metal
Tank any idea where this could come from
@@gonzalotorres4570hey sorry to bother you.. i have same issued like ur car.. but may i knw did you detect already whats the signs problems that may caused?
Hey. My 1977 corvette has recently started to have a hiss in the radiator and there is a slight and occasional coolant leak. Took it to a rad specialist, who told me it should be fine for the time being (I'm taking it in in a couple of days to get sorted out). However; the car has developed a clicking or almost knocking sound. Checked the oil, no lack of pressure or milky texture. There isn't any smoke coming from the exhaust, and the car runs and drives well. I'm sure the engine is on its way to overheating, but I'm terrified of a head gasket going out.
Overheating can cause engine knock if it stays hot enough to cause damage. You should have the car checked by a mechanic before using it anymore
Did you figure out what it was ?
@@12wegohard ohyeah, my radiator was leaking. Pulled it out and sent it to a radiator shop, haven't had any issues since (this was half a year ago now lol)
@@nonamel6377 yo question. How much did that cost you?
@@FlipBoji radiators depending on make & model go for about $400+
I have an rx8 and I noticed a few days ago white smoke started coming from my exhaust on a cold start and my coolant levels are normal no mix on the dip stick and the smoke immediately stops once the car is warmed up. And there has only been one misfire since I noticed the smoke.
I would keep an eye on it, cold start up with a little white smoke ( condensation) is normal but if the misfire is associated with the burning of coolant that will be a problem. You could get test strips that test the coolant for any signs of exhaust gasses to see if your head gasket is starting to go.
Rx8s don't have head gaskets
Wow, good call, must of forgot about that and was thinking about a conventional Mazda combustion engine, not rotary. Even though they don’t have head gaskets they are still coolant reliant and can leak from various seals and places.
my tacoma is smoking out the tail pipe when it cold but once up to temp it stops I feel a little loss of power and it vibrates more is it completely blown or would k seal maybe work?
Hard to know for sure but some light white smoke is normal more like condensation when cold. You may have a head gasket starting to fail, I would stay away from any of those additives, most never work and if they do only for a short period of time.
Thank you buddy I caught my over heat right after I got off the highway and by my coolant outlet pipe it was hissing nd water or oil on it
Great, glad to hear you caught it in time!
I recently found that milky substance under the filler cap and on the dipstick of my car and a few days ago I had the oil changed and used motor flush to clean out the engine. So far the oil has remained clean and normal and the car runs normal and doesn't overheat or emit any white smoke. I assumed it was just condensation due to the winter weather and only making short trips in it, keeping it under 20 miles a week. It does consume a lot of coolant with no leaks in the bottom and it the fluid inside the radiator is dirty and oily despite installing a new radiator six months ago.
Doesn't sound good. Your head gasket is probably on its way out. Should not consume coolant or have milky substance in the 6 month old radiator. You should have the coolant tested for any exhaust gasses mixed in with. If you do, replacement is the only cure.
What about oil leaking from the seam That separates the engine block and cylinder?
That’s a good point, it’s rather rare but does happen on a lot of Subaru’s and that’s also a sign of a blown head gasket.
My coolant levels keep dropping about 1/4 cup a month. No visible leaks on the ground. No smoke from the tailpipe at all, no visible signs of coolant in the oil. Doesn't overheat. Temperature gauge stays just below half way. Car runs perfectly fine though. It's a Toyota so I use the recommended red coolant. So when the car was completely cooled, I took the radiator cap off and started the car, and coolant immediately started to rise, but no bubbling whatsoever. Is this a symptom of a leaking head gasket?
So, when you say the coolant immediately rises when you start your cold engine, does it overflow and spill out? Also try when the engine is cold overnight and radiator cap it installed start it and immediately check to see if the large upper radiator hose has pressure, it should have pressure within 2 minutes or less
@@motorcarnut Yes, it does overflow, but slowly.
How do I check the radiator hose pressure? Do I need a pressure gauge?
....also it stops overflowing once the car reaches its operating temperature, and fans kick on.
When the car is overnight cold, squeeze the top radiator hose before starting the engine and feel how it feels with no pressure in it then start the car and immediately squeeze it again and see if it feels the same when it was off. Should not have pressure until the car is hot, if it has pressure let’s say with 1 minute after starting then the pistons are pumping up the coolant system because of bad sealing between the block and head and probably the head gasket starting to go.
Ok that’s a good sign that’s it’s probably fine. Try what I said above.
Very helpful video thank you I have that same problem where the coolant is not mixing with the oil......coolant runs low when I drive it and leaks different places below the vehicle...is it cause their is a blockage in the combustion chamber?
Thank you, well it depends where it’s leaking from underneath the car? Could be a leak in the radiator or hose or pumping up the coolant overflow and leaking down underneath as well. You have to see the location where it’s leaking from first. Good idea to dry everything as best as possible then watch where the leaks are coming from
I did not catch my over heating in time and it blew some sort of valve and drained all the coolant. I had that fixed along with the thermostat, but it's still over heating and I hear what sounds like gushing/dripping above my feet when I drive. I don't see anything coming out and I don't see anything leaking on the ground when I'm stopped or parked. I watched for white smoke today but didn't see any. The mechanic thinks it might be a head gasket that blew with the original over heating. I noticed when I lifted the hood this morning that the reservoir cap had blown off and broke. I'm assuming I need a new one of those for sure. Any other ideas?
The reservoir cap can not just blow off I don’t care how much pressure there is. You should find another mechanic and I think from what you’re explaining you did blow the head gasket or can be a cracked head or block but more likely the gasket. The gushing noise as you described is boiling coolant.
My mechanic sees the 'milkshake' but not on the diptstick, it's leaking in the engine. He was testing the heating core cause we have no heat. He said the oil was very low and had to add 3 quarts of it (it was changed 3 months ago). Also he pulled out the oil filter and it was saturated with oil. Looked like it had been dipped in oil. He said the place that changed my oil did not change the oil filter which led to the issues that he says may be a damaged head gasket. The car has not overheated.I don't know what to do. Any suggestions?
If there is mixing of coolant and oil, you probably have a blown head gasket at a minimum. How it happened I can’t tell by your post but either way that’s what it sounds like. Maybe get a second opinion to make sure?
How long should I wait for the smoke to clear after I’ve done an engine overhaul on my car?
What was wrong with the engine before the repairs?
I have a 2017 Honda civic Turbo. It is not blowing nearly as much smoke as that Mazda. But when I’m at a red light- and then go once it’s green- it blows a good amount of white smoke out. Smells like burning oil. Just got an oil change yesterday. Seems to be worse.
Can be the turbo
Great video! I have a question I have a bmw 114i and the coolant reservoir boils if the car has been driven for about 2 miles. There is a slight white smoke coming from the exhaust when it has been idling for a minute or so but once you rev the car a bit it goes and doesn’t continue whilst driving any help would be appreciated! Thanks
Something is making the car overheat OR a blown head gasket is pumping up the coolant system as well. You should start with the simple things first. Make sure the radiator cap on the reservoir is good or just replace it. Also, try this, leave the car cold overnight and then before starting it squeeze the upper radiator hose ( the large one) and get a feel of how soft it is, then start the car and wait about 2 minutes and see if it feels the same, if it's harder than when it was cold only after 2 minutes then the pistons are pumping up the coolant system from a probably blown head gasket. Because 2 minutes isn't enough time for the engine to normally build up enough pressure to feel harder when you squeeze it, Make sense? Other things is from a dead cold start without driving the car, how long does it take for the overflow tank to boil over?
@@motorcarnut it takes about 10 minutes of driving to boil, I’ll give what you said a go
I forgot to add the car doesn’t overheat (that I know of) the oil isn’t milky or anything like that and the car still drives perfectly fine despite the boiling coolant. I’m not sure how to find a temperature gauge on this car as it doesn’t have one on the dashboard
The "boiling over" IS overheating.10 minutes is kinda of a good sign because that doesn't seem like the pistons are pumping up the coolant system. Like I said try replacing the coolant cap, it's cheap and can cause the overheating by not holding pressure. I know a lot of cars don't have coolant gauges and some you can't even check the engine oil. It's ridicules. They want you to bring the car to the dealership so they can make money off you, no other reason.
@@motorcarnut I also forgot to add that there seems to be some red/orange stuff that looks like it has boiled on to the reservoir where the bleeding plug is I don’t know if there could be something linked with it. I asked a mechanic about it and he said it’s nothing to worry about but I’m not sure.
Great video! I have a 2008 BMW 116i and after a fairly long journey my car is violently vibrating and I have a yellow oil light on. There doesn’t seem to be a coolant leak and the oil level hasn’t changed however my Rev limiter is bouncing between 600-750 rpm rapidly. Any suggestions?
Could be a bad vacuum leak somewhere? Does it have any codes?
@@motorcarnut I am unable to find any codes but the problem isn’t noticeable when driving the car, it is only noticeable when fooling after a long drive if that helps your diagnosis. Furthermore, the radiator runs exceptionally loud.
Hard to diagnose without being there but sounds like what i said a air leak somewhere, a hose popped off? Fans running a lot could be a head gasket starting to fail , meaning the engine is running hotter than normal but the computer doesn't see that condition yet. Like I said hard to know without the car in front of me and I don't want to steer you in the wrong direction so you may have to have someone look at it for you before it gets worse .
I am losing a couple oz of coolant every 150 miles. No big clouds of steam. No leaks. No codes. No rough idle. It’s a total mystery! 2011 4Runner. 245k miles.
Got to be a leak somewhere or you’re burning it and don’t see it yet.

I have a 20i18 jeep wrangler. It started overheating by the time i turned to my house...i saw that the antifreeze reservoir was empty. I put 50/50 antifreeze fluid in reservoir. Then the next day it start with white smoke from tailpipe and got up next morning now it wont crank up...what can i do to get it fixed?
Sounds like a blown head gasket to me. I have many videos on head gasket repair.
Hey when im sitting idle at a red light, the temp gauge moves a little above the middle, then when I accelerate it goes back to the middle. What do you think this means? Some said radiator fan is cracked or thermostat. Im in a 09 Buick Lucerne super.
If the car has no symptoms as I explained in the video then it could be a failing thermostat. Also make sure the coolant is clean and properly filled and system has no leaks.
My pt cruiser only runs hot when the coolant gets to boiling point then it runs to reservoir bubbling and it doesn't go back to radiator so it's dry and start getting hot and we lose coolant out the reservoir hose is it my gasket or air in system or icm or the thermo or coolant sensor. I straight wired my high n lol fans but now that don't work. The fans just quit working today Fri Nov 12
Well you have an overheating problem for sure. Could be as simple as a faulty radiator cap or stuck closed thermostat, or the head gasket. You should get the fans fixed properly not wired manually the computer controls the fans so the car doesn’t overheat.
My Jeep compass has been running hot but no leaking any where. Not under the car or from my exhaust. I just got my coolant flushed but they said it was very chocolatey. I don’t know what to do next. Should I get my radiator flushed? Please help me
The head gasket is blown. Oil is mixing with coolant. Head gasket should be fixed first and sooner than later before it makes things worse.
how long will your car smoke for if your head gasket is blown or leaking?
If it's indeed a failing head gasket and leaking into the combustion area, Always. But can also be mixing with Engine oil and really no smoke at all.
Thx! I got my 2000 gmc sierra 1500 head gasket replaced. My profile picgure is my 2000 gmc
Great! Should last a long time now!
Hi there! Did replacing the head gasket end up fixing this customer's car? If action was taken immediately after noticing white smoke, can you avoid damaging other parts of the car? I have this exact problem and symptom on my mazda 3. Going to flush the coolant and add Irontite with new coolant. Hopefully that acts as a solution for now.
Yes it did and yes you can damage the engine even more than a head gasket such as warping the head or cylinder block and more.
No fuckin water temp gauge... r u kidding me Mazdahh
A lot of manufacturers are doing that now, makes you think why?
Hi my Suzuki is also boiling when the fan goes on the water go to level low.... Now the problem is the water on coolant is drying I have to fill up every morning I dnt see any leakage can it be the headgasket or the seal cap is putting more air on it... How must I blow out the air
Try a new radiator cap first, if not vehicle should be diagnosed by local mechanic
Tnx will try that aiy is giving stress
You won't believe I tried radiator cap now the car is bck to normal no boiling.... Thanks a lot
@tshepomokgoro2941 of course I would! I’m glad that’s all it was! Always start with simple and cheap things first.
@@motorcarnut❤
My car looses coolant but there’s no leaks, I changed the radiator couple months ago due to coolant leaking, and the coolant sometimes bubbles, could it be the radiator cap I haven’t changed that and the oil looks fine, I do need a oil change soon, what could be the problem?
Yes, it can very well be the radiator cap with the symptoms you’re describing. Always start with simple things first.
When I drive my car hard for a long period then stop and idle , plenty water falls on the floor and white smoke comes from engine Bay Area
Sounds like the heater core is leaking
I have excessive white smoke but goes away after like 5 minutes when I start in the morning or when the car rest for like couple hours. What does that mean?
Can be the first signs of a failing head gasket.
I have a 2010 Hyundai sonata when I bought it it had a coolant leak out of the thermostat housing replaced it with a aluminum housing and it seemed to be fine the thermostat gage doesn’t work nor does the gas gage I drove it it for weeks but today on the way home we heard a pop under the hood pulled over in a parking lot and under the hood the hose from the heating core was popped off the housing (bottom one)
Put it back on opened the radiator cap and it was clogged with black puddy or something I dug it out and you could hear some pressure release I filled it back up with maybe a quarter of coolant and the rest in water and when it was burping it was foaming a little bit also the coolant reservoir also had some black sludge in it
You blew the head gasket
