- WHY COOLANT IS BOILING IN THE COOLANT TANK RESERVOIR ON A CAR
If have a car and the coolant is boiling, antifreeze is boiling and you want to know some of the most common reasons why the coolant is boiling, antifreeze is boiling in this video we will explain that. It does not mean 100% that you have bad head gasket if the coolant is boiling, antifreeze is boiling. In some cases it could be something as simple as bad thermostat that could cause the coolant to boil, antifreeze is boiling. Air in the cooling system, if you did not bleed the cooling system the right way could cause the coolant to boil as well. Check the radiator fan, coolant level, test coolant temperature sensor and test radiator fan as well. Always inspect/replace the coolant tank radiator cap as well because bad radiator cap can cause the coolant to boil , antifreeze to boil. Hopefully the video will be helpful to any of you that need help with this.

Thanks for the technical tips, listing everything I think it might be a good start for me to replace the radiator screw cap.
I hear boil behind my dash. No boiling in my reservoir. Has a new thermostat, new hoses, fresh coolant, truly has me stomped
Probably air trapped in your heater core or clogged heater core. I’d flush the core then bleed coolant system very thoroughly. When you think it’s bled all the way, do it again. Air can easily stay trapped in there
@@FordSkaterhow to bleed?
@@steven97_depends on what car it is. I’m sure there’s a tutorial for your specific car on RUclips
Respect
I have a 2000 audi A6 Quatro 2.8 v6 it has a noise like coolant boiling or hissing coming from the plastic coolant resivor however it stops when I take the negative battery cable of and dosen't make noise again until I run it for a few minute I just replaced water pump and thermostat. I don't know much about these vehicles any idea's thanks
I recently tried the turtle wax inside job graphite and ceramic cleaner and protector and I liked it a lot maybe you guys could do a review on it, love the videos keep it up!
What do you guys use for coolant reservoir tank leaks do to minor crack/holes?
Sometimes the small hose to overflow tank gets clot with sludge so don't forget to check that.😉
I own a 1987 Ford Thunderbird and I took it for a drive to get catalytic converter fixed and once I got home it started spilling orange-red coolant all over the ground and the reservoir started rumbling like a pot when you cook soup. What could it be?
This happen to me with my mustang every time I race the engine it wouldn’t over heat but when I shut the ride off and park it after pushing the engine over 4k RPM, the coolant would come out of the coolant cap steaming, I started stressing about it because I thought it was a bad head gasket but i check the oil and there’s no milky liquid or signs of coolant in the oil and I check my exhaust and there no smoke whatsoever so I checked my thermostat and it was stuck half way open, jammed I would say and my water pump was giving out making a whine, but the signs I seen with my damaged thermostat it would take 15 miles to get to normal temperature and my gas MPG was bad and everytime I pushed the engine the temperature gauge would slightly go into the heat side until I let off the gas it would cool down, but I changed out the water pump and thermostat my car doesn’t do that anymore
I was looking for that “one mistake” I made. I heard everything I’ve already tried or thought of.
our 1994 RAV4 just came back from teh shop for timing belt. Now the coolant is boiling in the reservoir. The shop put on a new radiator cap because they said the old one looked worn.
The car is not overheating
I will try to bleed it today, thank you for the video
Can it be the head gasket even if the car is not getting hot?
I think the transmission cooler problem is there, or the gasket cap or thermostate valve
If there is signs of leakage on top of the expansion tank as well as the engine overheating would that be a faulty cap?
Did you fix your problems with the overheating? I have the same issues as uou described.
i have a question someone plz help me.
my car is making small bubble in the radiator and i see the coolant in my reservoir goes up but not overheating... what is the problem? plz help😢
I’ve got a 2006 Honda accord just put another motor in it all new gaskets from top to bottom after 250 miles the reservoir started boiling not overheating. What do you think that might be?
Air in the system?
BUT WHAT if expansion tank is way above maximum line, and radiator starts at full immediately after replacement radiator and fill, but the next day overflow reservoir tank is way above maximum level adn coolant in radiator lowers so cant be seen. So i siphoned off coolant out of overflow tank, then filled radiator to top level again. Went a couple cycles like that. Confuisng. 2008 nissan xterrra, which has a pressurized coolant reservoir overflow cap, non pressurized radiator cap.
Okay on my 2016 Chevy Cruze I done replace the hoses the Overflow container to the Head cracks in it but the holes leading from my thermostat liquid is cold but all the other hoses are hot and it's a leak under the thermostat at but I believe it's coming from the housing could that be the reason my car is overheating
I found out that I had a leak from the housing connecting to the engine is very very small you can't see it but that's where it was coming from and also my thermostat wasn't closing so that whole stay cold but I fixed it all now everything is fine
Because the small cars is over heating you should remove radiator cap.
And then change it
💯💯💯
Does dodge challenger have 2 water pumps ?
Hello! I recently replaced the radiator on my ‘19 Chrysler Pacifica. Afterwards, I burped the coolant with a big funnel, but now the coolant level on the expansion tank is a bit high after the car seats overnight. Soon as I open the cap it makes a whoosh sound and the coolant level drops about 1.5 inches. Do you think I may still have air in the cooling system? Should I repeat the burping process??
did you gets a solution?? because i have the same problem
@@zafir3831 Yes, I found the issue. It was the Coolant Expansion tank cap. The two seals on the cap were swollen & deformed, therefore it would not hold pressure. I replaced the cap, problem solved.
a question did you see small bubble in your radiator?
@@zafir3831 The radiator is sealed, you cannot see it. If you mean bubbles in the expansion tank? Yes.
okay thanks😊
Both my oil and coolant temperature is normal. I am also not losing coolant. But after I shut down my engine from 45 minutes of driving, i start to hear hissing sound coming from the radiator area. Coolant level also rise quite high in the expansion tank. I don't see coolant spraying. Sounds like intermittent air venting. This is first time i am experiencing this so i don't think this is normal. Anyone?
I’ve been filling up my coolant and the reservoir is empty by morning. I filled it up again and turned on the engine to find out where the leak is coming from. When I turned my engine on the and left it for about 10 mins, the coolant was boiling and pouring out of the cap. I checked my oil and it doesn’t seem to be contaminated. Is the issue just from a faulty cap?
I have exactly the same problem, did you solve the issue? If so, what solved it?
Boiling means air is getting in system somewhere, more than likely the engine.
truth. flushed coolant recently at the shop and it boils and overflow inside reservoir. massaging the hoses worked well.
If it's a Diesel it could also be EGR Cooler.
Dude looks like Oscar pistorius and sounds like him
Hey Guys,
Great video! Maybe someone could help me out :(
I stopped at the petrol station to fill up. I had the coolant checked. I then continued on my journey. After a while I noticed smoke coming from the engine. However, the car was not overheating on the sensor.
The car then cutoff, and wouldn't start. I then opened the cars hood to find that the coolant tank cap was not replaced. The coolant was also boiling in the tank, and leaking out the bottom.
Car wouldnt start. Any help, please :(
Its a 2014 ford fiesta st
Wife's truck, coolant boiling, just replaced water pump and thermostat. No heat, idk what her issue is, it's -2 outside so lol gonna have fun looking this up
Did you get her done?
dude how do you bleed the coolant system? none of your videos for this car tell us how. if there even is a video, it doesn’t hurt to add the link in the description along with the other crap that nobody cares about…
I heard this boiling sound for a few days... Couldnt figure it out, but didnt actively search like an idiot. Last night at an idle the engine burst into vapor/smoke. White chalky liquid all over the engine! Pulled the oil dip stick and it seems the oil is regular color. Slightly light brown though. I cant tell where the fluid came from. Does the white liquid mean my head gasket is blown?
Yes
It was my radiator, cracked
Mazda CX7...I have changed... the radiator, the fan regulator, the thermostat, replaced head gasket with top end overhaul. Driving normally it is fine but as soon as I am in traffic, it boils over again? System was bled properly too.
HELP?
I had the same problem i fixed it today 🤦♂️
@@Kelvin-ri1xewhat was the problem?
Listen through the hole thing and still got the problem bc I couldn't understand a word that he said
Breathe dude !!
I have a question , I did the dumbest thing . I'm still learning from cars and I will admit I done stupid things before but this by far the dumbest. Idk why I was looking at my antifreeze. I saw it look blue from inside when I open the cap but was brown looking when I saw it from the outside. So Idk why I thought of smelling it. So I took the cap off and put one side of my nose and smell it and after I felt it kick. I look it up and wonder by so when I look it up I found out of deadly it can be. The car was sitting for a while so it wasn't hot antifreeze. But my question is did I end up damaging my organs doing this?
No. You should be fine
Why does he sound likes he talking underwater
Blessings, John 3:16. Jesus loves you.
My Škoda makes water gurgling noise from dashboard on ignition for 3/4 seconds and normal thereafter
Ant likely reason and remedy please?
Mine overflows after 15 minutes of the engine running. ( coolant cap is off and still over flows) temp gauge stays at normal 1/2 temp
U have air in the coolant system, get an OEM radiator cap and burp the system
I don’t have a radiator cap and I have this issue of boiling coolant, I got a new water pump /thermostat assembly put on I switched to a new coolant sensor, my motor sounds fine as it always did and I don’t see any smoke at all but yet I can’t seem to figure out this issue on a 2015 Audi A3
Are you found problem?
@@johnson1722 it was the coolant reservoir cap
@@Tjevdevs i must try on my car thanks
On my car I replaced the radiator. I replaced the thermostat. I replace the water pump and the sensor for the temperature gauge now after all of those things all of the water goes from the radiator to the reserve reservoir in if I drive my car after period of time. The temperature gauge rises to hot, but then comes back down.
I have a 2005 Nissan Altima 2.5 S cause I want tell me why is this happening
Bad head gasket
I changed everything samething is happening,the only thing left to change is the engine
Lol
I have a 2012 cruze....Mine did this every time I took off the coolant cap............Believe it or not I found a simple fix.....Anytime you have to take off your coolant cap...Take the neg cable off your battery...believe me it works.....No bubbling over.....
The issue is pinpointng the cause...expensive affair

I have an 03 Subaru forester, overheated today steam coming out the radiator cap, and coolant bubbled out. Could it be thermostat, water pump or?? Really hoping it’s not the fucking head gasket, I paid 4k for the thing not looking to do that again :(
Hey my engine coolant is boiling up but my car isnt running hot any suggestions on what could it be
Head gasket worn-out
That's 1 of the possible problems
@@thomashawk21 worn head gasket but wouldn't that cause coolant to get into oil if it was a blown head gasket?
@@leslietyler6597 when your car engine is cold open the oil cap on top off engine see if the oil is black or a coffee/ milky colour it’s possible it’s not boiling with heat but with air pressures could be a hole in radiator or if cap it’s milky fluid is mixing with oil so it will be head gasket there a liquid you can buy that can possibly help if original damage is not to severe fills in holes in gasket radiator cylinders ask your garage about it
@@thomashawk21 copy that. I checked oil actually changed the oil. And all I black. But still am having boiling in the reservoir. I checked fluid bled the system numerous of times and still have a rock hard upper radiator hose while running also upper hose is hot and hard but the bottom hose is not hard and is cold. I put new water pump and thermostat and a ebay radiator but it's still the same. May have something to do with my cats as they are the wrong one.
I had top gasket replaced and a new thermostat with a new housing 4 weeks back then flushed old coolant yet my car is still boiling coolant, however it is not overheating. Everytime i turn the car off it boils after driving for a while, then fan runs longer than normal to cool off the car. (2006 mini cooper) what could be the issue? Had the water pump checked aswell.
Update
I'm having same problem
@@agentsouthdallas what’s happening
My coolant bubbling in the overflow but it's not overheating. I got new water pump , thermostat, radiator, temperature sensor, I know it's not gasket. I can't figure out what can it be ? Maybe I need to change coolant@jay
@@agentsouthdallas mine is doing same thing I’m not sure as well
Put thermostat in,coolant,noticed since put new cap on it overheats bad and blows cold need fix it but does lek underneath water pump.....how fix problem before winter in 1997 Chrysler ciruss lx 2.5 ltr 6 cyl
Also when opened cap water shot out radiator like shotgun..why don't have heat and water pump located
Where's water pump and is it easy to take off and install on Chrysler ciruss 1997 lx 2.5 6 cyl
Please help me I'm new at this car it sucks!!!
What's the major malfunction????????
His voice kills me I couldn’t listen 😢
My car does this and radiator low people are saying head gasket but runs good no milky oil no white smoke?
Same here man on the side of the freeway right now
@@drawndown just manage to get my car home. So aggravating
@@Saintzoudid u ever figure it out ?
@@kramse21 I needed a water pump and new radiator cap.
@@Saintzou Hi. I'm having the same problem in my Chevrolet Cruze. Ny coolant is boiling in the reservoir and coming out of the tank. Today i replaced the thermostat but still it doesn't fixed it. My mechanic said that it could be the water pump or head. Does the water pump solved the problem in your case?
You know that sound of gurgling water? Listen closely you can hear it while he talks lol
😂
Sounds like hes talking under water
Ford figo over heating
I don't understand have the things you say
I don’t understand what you’re trying to say neither.
why am I struggling to understand what you said xd
I'm not over heating
First !
Please don’t say guys all the time, slow down with your speech please and those overalls are awesome except the are very short on the top half.
Peace and car grease.
This video is not detailed enough
Sounds like you’re drowning in water
Dude, please breath.. i only listening and i am hyperventalating..
You’re very knowledgeable but you talk very fast with your accent..
Still understandable. Good english
Sorry but i can hardly understand ur accent dude
Tips are helpful. The speech w/ gargling sounds you make is a real turn OFF & is why I DON'T watch more of your videos. Also pls stop saying "guys" in every other sentence.
You still watched it tho fk
You need to work on your English accent I can barely understand you
Speak slower. Your accent is hard to follow
