Mine was air pocket in system on my 06 GMC envoy all I did drain all the coolent out then I put in coolant then turn car on. And the top it off with more coolant then left it running till thormasta opens up then air bubbles came out I left it bubble up till it stopped and it did and then I close radiator cap and left it running and good no more overheats thanks for. The video it was air pocket in the system now my heater works good now
Very good bro. I will turn on my heater and it sounds like something knocking. It works. But my radiator was getting hot. I could hear it steaming after I turned off the engine .I waited about an hour and opened the cap and it still blew out steam. You and your family, stay healthy brother.✌️💙🏇🏇🏇
Thank you so much - this has really helped me. My car heats up when at the stop light or slow driving in traffic - so now mechanics in my country won't lie to me - i am informed. Thank you so so much.
@@Fade9d9 well I replaced my thermostat & the radiator cap. After changing The thermostat I was still have the same issue. I watched a few videos and they kept talking about how the radiator cap could also cause this. I changed the cap and my car had not over heated again. I believe it was the radiator cap being super super dirty with gunk and dirt. Start replacing the cheap stuff and work your way up.
My radiator cap was not holding enough pressure to keep it from boiling. New cooling fans, fan relays, thermostat, drain and new coolant, serpentine belt. Stupid radiator cap was the culprit.
Here’s a trick to check the cooling fans just turn on your ac on max the ac system needs the fans to run to operate correctly. The fans after 2 to 3 seconds should fire up and run. If the fans work with the ac but the car still over heats with the ac off then check relays. The way it works is the computer will ground the cooling fan relays and turn the fans on since the fans can be run at different speeds you may have a few relays controlling the fans. The reason I say try the ac first is because if the fans run with the ac then that tells me you have a relay issue if the fans don’t come on with the ac then there might be something wrong with the fans themselves. The fans will always kick on with the ac turned on full blast.
Well my fan turns on with the AC, but it doesn’t work without the AC. I’m curious to know why my car still overheats when the AC is on with the fan running. Please give me some advice 🙏
@@oprahd.lizard2984 if the fans come on with the AC on but the car starts overheating with the AC off then yes you have something else that’s wrong. Once the temperature reaches a certain point the computer will kick on the fans usually at low speed depending on how hot the cars getting. You’ll have AC fan relay and usually 3 relays for fan speeds. When the AC is on the fans run at full blast that’s how the AC works when the AC is not on and the car starts to get hot the computer will kick on the fans at low medium or high speeds. This is typical if it’s a hot day and your sitting in traffic not moving the engine gets hot with no air passing over the radiator so the fans might come on at low speed. So to sum up if the fans work with the AC but not with the AC off check all the fan relays. When the temperature gets above 200F or 90C they should kick on.
@@thankgoduzoma82 you might have a blown head gasket if it’s still getting hot with the AC on. Plus that might have happened because the fans didn’t work with the AC off it got to hot blew the gasket.

Our 2016 Jeep Patriot overheats at highway speed with no warning light. We checked the fan, fuse, relays, coolant levels...all fine. Im thinking it's either a clogged radiator or bad thermostat. Am I likely on the right track?
Great video and thanks for all the info. I have a 2007 Toyota tundra and my problem is when I go fast and requires power. My temperature starts rising. But if slow down or stop it comes down.

Really cool to see you replying to comments a year later. I have a 2016 Subaru outback 2.5, after about 40 minutes of driving the needle moves up to red then slowly goes back down to normal. It will do that a few times during the ride. I also notice the heat will then fluctuate between hot and cold. I’ve read online it could be the radiator cap but I replaced that today with a Subaru oem cap and still the same. I’ve also read it could be low coolant. I plan on changing that tomorrow. I just wonder if there’s anything else I should consider?
having exactly same issue. Bout to try changing thermostat and also bleeding the system. Havent checked my radiator cap yet, could be that or the coolant temp sensor.
Mine was a clogged radiator. I bought a used car and discovered that there was tap water in the cooling system. Fast forward a few months and residue built up in the cooling fins. Had to replace cooling hoses and radiator. The engine also didn't have a thermostat so I just bought a new one and installed it.
I have a 2000 Acura RL and this started happening a week ago where my temperature goes up and then back down to normal and when it goes up I get scared thinking it's going to overheat but it never does I hope I can find the problem and fix it soon 👍
This is happing with my 06 RL which i use as a daily driver. I replaced the radiator, radiator cap, thermostat, water pump, engine cooling fan, coolant temp sensor and did a coolant flush. There is no loss of antifreeze. However, I did notice that my ac fan and ac is not working. I will be fixing this issue soon.
Thank you for your teachings. I’m having that issue lately, my van for some reason works perfectly, but what I go passed 35 to 45, then it starts to go higher, but when I drive it for at least, 3 minutes and stopped, and for at least, 20 minutes, it drives nicely and go to to 55 miles per hr. I don’t know what happening. I will go AB’s check the fan later today. But in case you have any other ideas why it’s having this over heating issue, please let me know thank you
Great info. I've had my truck in the shop twice now. They replaced the thermostat & housing. Drove 15 miles temp spiked, took back and they said it was a faulty part. Well, same thing is happening again, 15 miles and temp spikes. Would you think that the system has air in it?
@@eatshiyno. 4th time in. They replaced the radiator again and said there was some sand in the reservoir. They said it was probably from the engine cast which I’m not sure I believe It’s still running kind of hot and after a 30 minute trip it gets into the 220s which they say is normal. I just need to suck it up and take it to the dealership I guess
1999 tahoe only overheat a little on first startup after being cold. Then runs normal. New thermostat. New hoses. Clutch fan engages. Good heat. Burped the system. I'm thinking coolent temp sensor but how do I test?
I have a 2012 F150 with the 5.0 and I just got the water pump and thermostat replaced, but now my engine is overheating Still haven’t figured out the issue. But this was definitely helpful!
ive taken care of everything except the water pump and a couple of sensors......then I added some fuel type cleaner to my gas tank and that is the only thing thats made a difference so far. carbon gunk does pileup sometimes. And I dont over do anything....I use only what the directions in the fuel cleaner says to do. But there was a gunk build up on the tailpipe so I thought of the fuel cleaner.
Sir. Very good video. I bought 11 years old diesel car with1148 cc engine. It clocked nearly 1,50,000 kms. It has a 5 dots type engine temperature gauge. It hardly exhibits one or two white dots. If temperature is normal, then how many dots should appear? Plz guide.❤
?? I'm going through this right now thanks for sharing but what if I see white smoke coming out of my tailpipe is that a bad problem I haven't ran my car for 2 weeks because of this
I have an 06 GMC Envoy Denali and it's overheating, but doesn't seem to be really hot - I suspect the Temp Sensor. The temp gauge at highway speeds will show increasing temps and it will hit the top causing a beeping sound, but then the temp goes down and there's no sign of actual overheating - just a constant up and down on the gauge.
I’m having this issue with my 06 350z I’m not sure if it’s the water pump or the heater core. My question is can a heater core cause this problem? I only over heat when in idle for too long but only when outside temp is higher than 90 degrees. But when it’s over 100 degrees,even if I’m driving it will over heat. I’ve changed the thermostat, radiator and pressure cap. No air in the system
My old on Yukon valley it's overheating only when I'm pulling my trailer. A little heavy but I've been pulling it for three years now. In December I replace the radiator and the hoses and the thermostat. Any advice would be greatly appreciated. Thank you. 🇺🇸💪🏻👊🏻🤙🏼
If everything with the engine checks good, I would check out the transmission. Automatic transmissions can cause overheating, especially when hauling heavy loads and cause the radiator to overheat.
I resolved my overheating issue after checking everything else. Would have saved money and time, if I checked the bottom of the overflow reservoir for dirt which was blocking the hose to radiater.
My truck starts to heat when turned on by at a stop. The temperature gauge goes up and the a/c begins to warm up but as soon as I am driving it, it cools down. What might this be?
I replaced the thermostat the fan coolant fan and i still see the 2004 Toyota sequoia sr5 onl;y overheats when im on long trips over 50-60 miles an hour , I dont know whats going on but it blew a few lines the other day in traffic i limped home after repacing all the blown lines and replaced the tee valve and turned the heat on it works fine, I dont hear any water pump noise nor do i see anything leaking, its not over heating idling, I originally had this problem from day one , and they flushed the system then they said the coolant fan needed to be replaced I did that , none of this worked so I did thermostat today again that dint work in fact thermostat looked fairly recent new maybe i need to flush it again? for what its worth, i dont see coolant circulating with radiator cap opened, it just blows hot burning coolant out at me
On my old Lincoln LS the procedure to de-air was to park the car on an incline. Meaning the front of the car higher than back. Open the coolant port and run the car with heat. This causes water to circulate and air to rise and exit out. After about 5-10min close it. Then use the bleed line. Some cars have a small port you can open and it bleeds out some coolant. For what it’s worth hope it helps someone
How do you get air pockets in the system? I had my car for over 2 years now, and today while driving I noticed the temperature raising to the top and back to half way and then back to the top, another thing I noticed my tachometer needle was at around 1000 rpm when is usually at around 650-700. when I checked the coolant levels I found out it was empty so I filled it up but still doing the same thing and my cooling fan was running all the time while my car was in my garage, Is it supposed to do that?
Mine does the in town heat climb.I noticed when i turn my AC on it helps to control the temp.So what would this be, i swiched my ECT sensor twice, duralast and pigtail ,is it just too cheap of a sensor?
I have a Chevy Colorado 2015 I’ve changed the thermostat. I’ve changed the radiator and it continues to overheat. I have to turn the heater on to cool it down. What do you think the problem could be
So I have a unique issue with my 2015 wrangler 3.6 engine spiking to 230-240 mainly under stress at speeds anywhere from 40-75 mph. It some times will randomly do it but mostly on a slight incline. Then it will drop back down sometimes to 200-216. I am not loosing any coolant and it’s holding pressure. I put a 3 row radiator, replaced the thermostat 4 times, replaced the coolant temp sensor 3 times, replaced the water pump twice, new hoses, the fan comes on when it’s suppose to, I have recently had the head gaskets done twice as the mechanic thought that may be the issue. I am using mopar oem coolant. I had the catalytic converters tested and they are good also. I have good air flow as well. I have burped it over 100 times since June. So I don’t feel like there is air in the system but possibly could be. I’m at a loss at this point. Any advice would help tremendously
Man, I have a beautiful 02' Blazer ZR2 4.3 w/300k on her & she used to run at 200 on hot days with a 195° thermostat. Now she's running around 210° (1/2 way mark) after driving just a few miles on hot days. Then it'll raise a tad past 210. That's never happened. The water pump is pumping. I can see it flowing when the thermostat opens. Maybe this is normal but I've never noticed it in the past. She'll get a tad higher when towing a very small 5x9' utility trailer with 200lbs in it. I'm South of Houston. I've flushed, cleaned the outside of radiator, not loosing coolant, did a flush twice in the past 2yrs & didn't look bad, got a new 195° thermostat, coolant, Severe Duty Clutch Fan & I've purged my system twice. I believe all my air is out. The new fan is odd, it is working or engaging when parked & getting warm or just after the thermostat opens, it just doesn't cool it down much or I cannot hear like I can when I'm driving but it's working. It's a new Hayden 2786. Might be normal because it runs around 200° in the mornings & holds that temp whether towing or not. It's just when it's really hot outside like 90° or higher when the temp runs hotter than normal. Which is probably just fine & me worried about nothing. She's had a ton of work done to her & runs like new. Still getting the 02' sticker mpg, 16 in town & better on highway.
@@SkittleEagle bit the bullet bought a new suv off the lot and sold my blazer it still ran like a champ though just didn't want to risk putting anymore into it if something did happen
Could it be the ect sensor even if my car isn’t throwing a trouble code for it? I’ve had to replace a thermostat on my car that got stuck open and it threw a code for ect/thermostat don’t recall the exact code so wasn’t sure
So I changed my thermostats n when I took it in they flushed my system and was fine for a while now got issues again but he mentioned I got the wrong fan in my car so maybe that’s where? But then I notice wet under my car bubbling sounds from the car when I turn it off and when it’s cold it won’t warm up but when it’s warmer it’s not a issue so I wonder if it’s either a water pump or a leak cuz I’ll even put in over the over flow it will still quickly go dry n it doesn’t always over heat but sometimes
No offense, love the video, but the coolent Reservoir you spoke of in the beginning with the high/low and was pictured dull white plastic is for overfill level, It's not your coolent level. To test the coolent level, you just fill the the radiator more and more until no more can go in. If more coolent can go into the radiator, then it's probably not full. As said later, you may have airpockets so keep on trying to fill it. Make sure it's the right kind, too.
@@josediazasmr6014 wud only get bit water in a cylinder mainly wen cold shut off as once started may run rough clearing up once at runing temp as long as water topped up & not boiling due to low level = air/ air lock pockets = overheat. if do stop shit leak bypass heater core & entire rad if u have ability/ if not remove thermostat run till hot allow sufficient cool time reassemble. ☆JoeDog&K-9'sBuddie☆
Actually on most cares that’s part of the cooling system and it’s pressurized. Good way to tell is if the cap reads don’t open when hot that overflow is part of the system. If the cap on the bottle has no warnings on it it’s just an expansion tank.
Hey brother how you doing? I have a new radiator a new thermostat and all that other stuff is new but I did raise the front part and the air gets out. Trap are and I was able to put more radiator fluid in there and it helped I think. I've changed several CO2 sensors and other sensors. Just change the air flow sensor. I hope my car starts I'm not a mechanic. Once again you and your family stay healthy brother. ✌️💙🏇🏇🏇
My problem is so unique. My AC stops working. Only option to do, since all other issues are not the problem. I have replaced the thermostat several times, last time 5 months ago. I have not needed the AC, so I haven't replaced, even though the temperature gauge stops registering, but heater still works perfect, no engine over heating. I am trying to prepare for summer weather, what can it be? Is there a specific thermostat I need for a 2.2 engine? I am never asked when I buy them, which one I need. I have asked and the dealership has said only one specified. The dealers was $75 and still same problem in a few weeks. Help! Please.
I have a 06 Cayenne 3.2L v6, only starts to overheat when I go 75mph+ and it’ll go away when I slow down. But coolant reservoir blew up on me on the highway. So I replaced that. Not sure what could cause the overheating at high speeds
Can someone explain how the water pump fails. If the impeller spins how is it causing the coolant to overheat? Even if coolant is leaking out of the weep hole but the coolant level is not low what causes the overheating?
@HVACMECHANIC On my way home today my 2005 Mercury Mariner beeped and said "Hot Engine Temperature" I noticed the temperature guage was all the way on high, after I continued to drive a few miles just trying to get home from work all of sudden the truck just completely turned off right when I was about to make a turn leaving me stuck right in the middle of a busy street😢. I never got any warning prior to this so what do you feel the actual issue could be???By the way I did have my AC on and turned it off as soon as I noticed the temperature gauge was on high.
what if the coolant is leaking then stops? pulled over cuz gauge and steam indicated overheating, waited for suv to cool off, added more coolant to get home, it didnt leak that time but under hood by coolant was gettn warm again?
I just changed the thermostat. Its still overheating. Temp goes down when we open the cap to water reservoir. I think he bled it right. What do i do next. I cant afford a mechanic
My temps stay between 177 and 184 when the a/c is not on. Unfortunately when the a/c is on, I see the temps go up to 205. I have my radiator fans turned on all the time but even like this, the temps climb high with the a/c on. With the a/c on and at highway speeds, the temps will mostly drop to the mid 190’s depending on the outside temperature . I’m really hesitating on installing an oil cooler to assist because it just adds complexity.
Hi, I know this video is a bit old, but Iam having an overheating problem with my Subaru, Its a 2007 1.5R Impreza ( hawkeye ) - I can drive all day at lower speeds, and have a perfectly stable temperature, but if I take the car out for a long freeway drive and hold a constant 60-70mph, after some time, it can be after 30m or even 60min the temperature will all of a sudden start to climb.. all I gotta do is to let of the trottle and slow a bit down the the temp will go back down again. this is the second time ( second engine ) that has this happening to it, the shop told me they needed to replace the engine, and so they did, but also they replaced the radiator. ( big bill ) anyway, now after a few years after the first engine was replaced, I get the exact same problem.. the temp will go up at higher speeds after a long drive, and will cool down as soon as the speed is lowered. Any advise ?
I have a toyota yaris 2008, facing problem of overheating when on high speed like over 80kmh and when vehicle running for long time already changed radiator and water pump,still same issue,can u enlighten me with the reason please।
I have benz E350 and it starts overheating when I turn the ac on or when I am traveling at the slow speeds or stopped completely but it stays normal on freeway even with the ac on for long distance too but if I press on gas really hard or usually traveling at slow speed it is doing that for few months now.
The last thing could be a small amount of combustion going into the cooling system which will cause it to do those same symptoms plus make the heater go a to warm when it's on high heat.
Currently hunting the same problem. Only overheats on the interstate 60mph+ Flushed a bunch of rust out of the radiator system. New thermostat, New water pump, new mopar coolant. Still acting up. Also coolant temp sensor changed. Gonna try the radiator cap and if that doest get it, flush again.
I’d like to add #8 I was having to add a large big gulp cup every day. I couldn’t find the leak for the life of me. No drips no where. I finally started ripping out the whole front end! Out of the corner of my eye I finally see a drip… the back side of the radiator cap!
So I got the symptoms of a air pocket in the coolant system but when my car is idle it has a ticking sound It’s nothing to loud yet but i’m having trouble diagnosing it
Hi i have a 04 wrx with an ej207, have changed out the radiator due to a hole and replaced the ect sensor also but am now have the problem where the gauge is going over 2 3rds then the fans kick in and it drops back down to under half way, the scan tool is reading the correct temp for fan activation and the temp gun is pretty close to it also, ive bled the air all out and done a pressure test, system held pressure and im not losing coolant. Any ideas?
Humm, my 2005 F150 gauge went to hot, check gauge light came on. Changed the thermostat, and it did it again. I pulled over off, and back on, and normal temp. I slowly open the reservoir and it fills and would overfill if allowed. Looks like trying temp senor next. Any opinions are appreciated. Only work truck.
My 2012 chevy equinox keep trying to run hot. Then it go to normal, pretty much keep fluctuating.. sometimes it when im in traffic and sometimes when im driving on interstate
Im pretty sure its the fan on mine, i noticed if the car is idling the overheating jumps up but once I drive it drastically goes back down in heat N stays cool, i added more coolant and got a oil change plus prior the radiator transmission n fuel injectors was flushed... so it has to be the fan, luckily i live in a colder state while driving, just damn... shit popped up 3 days ago
Mine overheated tonight. I sat for a while it cooled down fast (30 minutes) So the resevoir was okay I didn't check the radiator tho I was afraid it, would be too hot! Then I tried to drive it. Got about a mile and bam same thing only worse. And there was no power for 100 ft as I drove it the second time...so I had to call a wrecker to go home. 😢 . what about bad head gasket does that cause it. I hope I didn't ruin my engine. There was no steam. There was no smoke. And only a trickle of antifreeze near my driver front door
I have Mazda 6 2002 year, i will drive like 15 to 20 mins even 30 mins before it will get overheat, no leakage, the temperature will go high and the car will stop and sometimes i will not add water but as soon as i on the car it start again, please what can be the problem tnx

3rd thermostat for me! Did you ever find out why?🤔
@@eatshiyno. 4th time in. They replaced the radiator again and said there was some sand in the reservoir. They said it was probably from the engine cast which I’m not sure I believe
It’s still running kind of hot and after a 30 minute trip it gets into the 220s which they say is normal. I just need to suck it up and take it to the dealership I guess
So did you ever figure your issue out?@@homebuiltwoodworking9664
Thank you ! Nice simple video . These other guys do too much
Great video! You done an awesome job explaining it all.
1999 tahoe only overheat a little on first startup after being cold. Then runs normal. New thermostat. New hoses. Clutch fan engages. Good heat. Burped the system. I'm thinking coolent temp sensor but how do I test?
I have a 2012 F150 with the 5.0 and I just got the water pump and thermostat replaced, but now my engine is overheating Still haven’t figured out the issue. But this was definitely helpful!
ive taken care of everything except the water pump and a couple of sensors......then I added some fuel type cleaner to my gas tank and that is the only thing thats made a difference so far. carbon gunk does pileup sometimes. And I dont over do anything....I use only what the directions in the fuel cleaner says to do. But there was a gunk build up on the tailpipe so I thought of the fuel cleaner.
Excellent, down to earth instructions. Thank you.
Sir. Very good video. I bought 11 years old diesel car with1148 cc engine. It clocked nearly 1,50,000 kms.
It has a 5 dots type engine temperature gauge. It hardly exhibits one or two white dots. If temperature is normal, then how many dots should appear? Plz guide.❤
?? I'm going through this right now thanks for sharing but what if I see white smoke coming out of my tailpipe is that a bad problem I haven't ran my car for 2 weeks because of this
with this intermittent heat problem... Can you now rule out a blown HEAD GASKET ?
I have an 06 GMC Envoy Denali and it's overheating, but doesn't seem to be really hot - I suspect the Temp Sensor. The temp gauge at highway speeds will show increasing temps and it will hit the top causing a beeping sound, but then the temp goes down and there's no sign of actual overheating - just a constant up and down on the gauge.
I’m having this issue with my 06 350z I’m not sure if it’s the water pump or the heater core. My question is can a heater core cause this problem? I only over heat when in idle for too long but only when outside temp is higher than 90 degrees. But when it’s over 100 degrees,even if I’m driving it will over heat. I’ve changed the thermostat, radiator and pressure cap. No air in the system
Did you figure out the problem?
Save my Pocket thank you for this information, bless up your self.
Mechanics have been known to place thermostats in place upside down . Cylinder head gaskets that fail may cause these symptoms .
My old on Yukon valley it's overheating only when I'm pulling my trailer. A little heavy but I've been pulling it for three years now. In December I replace the radiator and the hoses and the thermostat. Any advice would be greatly appreciated. Thank you.
🇺🇸💪🏻👊🏻🤙🏼
If everything with the engine checks good, I would check out the transmission. Automatic transmissions can cause overheating, especially when hauling heavy loads and cause the radiator to overheat.
If it is winter and freezing outside and you don’t have antifreeze or to much water mixed it will freeze in the block and over heat
To the point and on point with everything. New subscriber keep em coming.
thanks for the info do you have a video that show the bank 1/upper sensor location on a jeep grand cherokee 2012.....thanks
I have a Nissan Almera. The temperature indicator goes on to red even after changing the cooling...
I resolved my overheating issue after checking everything else. Would have saved money and time, if I checked the bottom of the overflow reservoir for dirt which was blocking the hose to radiater.
your great bud thank you for solutions so clear cut and to point no bull again so appreciate you
My truck starts to heat when turned on by at a stop. The temperature gauge goes up and the a/c begins to warm up but as soon as I am driving it, it cools down. What might this be?
Is your fan working, might blow/ spray out your radiator.
I replaced the thermostat the fan coolant fan and i still see the 2004 Toyota sequoia sr5 onl;y overheats when im on long trips over 50-60 miles an hour , I dont know whats going on but it blew a few lines the other day in traffic i limped home after repacing all the blown lines and replaced the tee valve and turned the heat on it works fine, I dont hear any water pump noise nor do i see anything leaking, its not over heating idling, I originally had this problem from day one , and they flushed the system then they said the coolant fan needed to be replaced I did that , none of this worked so I did thermostat today again that dint work in fact thermostat looked fairly recent new maybe i need to flush it again? for what its worth, i dont see coolant circulating with radiator cap opened, it just blows hot burning coolant out at me
On my old Lincoln LS the procedure to de-air was to park the car on an incline. Meaning the front of the car higher than back. Open the coolant port and run the car with heat. This causes water to circulate and air to rise and exit out. After about 5-10min close it. Then use the bleed line. Some cars have a small port you can open and it bleeds out some coolant. For what it’s worth hope it helps someone
How do you get air pockets in the system? I had my car for over 2 years now, and today while driving I noticed the temperature raising to the top and back to half way and then back to the top, another thing I noticed my tachometer needle was at around 1000 rpm when is usually at around 650-700. when I checked the coolant levels I found out it was empty so I filled it up but still doing the same thing and my cooling fan was running all the time while my car was in my garage, Is it supposed to do that?

Great video! Very informative. Thank you.
Thank you for all the insite
Mine does the in town heat climb.I noticed when i turn my AC on it helps to control the temp.So what would this be, i swiched my ECT sensor twice, duralast and pigtail ,is it just too cheap of a sensor?
I have a Chevy Colorado 2015 I’ve changed the thermostat. I’ve changed the radiator and it continues to overheat. I have to turn the heater on to cool it down. What do you think the problem could be
Timing
Thanks for your tips! I've tried everything!!
did it work for you??
So I have a unique issue with my 2015 wrangler 3.6 engine spiking to 230-240 mainly under stress at speeds anywhere from 40-75 mph. It some times will randomly do it but mostly on a slight incline. Then it will drop back down sometimes to 200-216. I am not loosing any coolant and it’s holding pressure. I put a 3 row radiator, replaced the thermostat 4 times, replaced the coolant temp sensor 3 times, replaced the water pump twice, new hoses, the fan comes on when it’s suppose to, I have recently had the head gaskets done twice as the mechanic thought that may be the issue. I am using mopar oem coolant. I had the catalytic converters tested and they are good also. I have good air flow as well. I have burped it over 100 times since June. So I don’t feel like there is air in the system but possibly could be. I’m at a loss at this point. Any advice would help tremendously
Can they do your wiring?? Mine does this, changed the switch but still the temp indicator goes to the red and back to normal
Man, I have a beautiful 02' Blazer ZR2 4.3 w/300k on her & she used to run at 200 on hot days with a 195° thermostat.
Now she's running around 210° (1/2 way mark) after driving just a few miles on hot days. Then it'll raise a tad past 210.
That's never happened. The water pump is pumping. I can see it flowing when the thermostat opens.
Maybe this is normal but I've never noticed it in the past.
She'll get a tad higher when towing a very small 5x9' utility trailer with 200lbs in it. I'm South of Houston.
I've flushed, cleaned the outside of radiator, not loosing coolant, did a flush twice in the past 2yrs & didn't look bad, got a new 195° thermostat, coolant, Severe Duty Clutch Fan & I've purged my system twice. I believe all my air is out.
The new fan is odd, it is working or engaging when parked & getting warm or just after the thermostat opens, it just doesn't cool it down much or I cannot hear like I can when I'm driving but it's working. It's a new Hayden 2786.
Might be normal because it runs around 200° in the mornings & holds that temp whether towing or not. It's just when it's really hot outside like 90° or higher when the temp runs hotter than normal.
Which is probably just fine & me worried about nothing.
She's had a ton of work done to her & runs like new. Still getting the 02' sticker mpg, 16 in town & better on highway.
I have the same problem
@@RICK32717same but mine revs higher like it's struggling any advice on what to look for or what it might be same 02 blazer
@@dblocksta92
Mine does the same, did you find the problem?
@@SkittleEagle bit the bullet bought a new suv off the lot and sold my blazer it still ran like a champ though just didn't want to risk putting anymore into it if something did happen
Could it be the ect sensor even if my car isn’t throwing a trouble code for it? I’ve had to replace a thermostat on my car that got stuck open and it threw a code for ect/thermostat don’t recall the exact code so wasn’t sure
So I changed my thermostats n when I took it in they flushed my system and was fine for a while now got issues again but he mentioned I got the wrong fan in my car so maybe that’s where? But then I notice wet under my car bubbling sounds from the car when I turn it off and when it’s cold it won’t warm up but when it’s warmer it’s not a issue so I wonder if it’s either a water pump or a leak cuz I’ll even put in over the over flow it will still quickly go dry n it doesn’t always over heat but sometimes
No offense, love the video, but the coolent Reservoir you spoke of in the beginning with the high/low and was pictured dull white plastic is for overfill level, It's not your coolent level. To test the coolent level, you just fill the the radiator more and more until no more can go in. If more coolent can go into the radiator, then it's probably not full. As said later, you may have airpockets so keep on trying to fill it. Make sure it's the right kind, too.
Idk about that cause your just adding water into the cylinders heads if you have a bad head gasket
it dep's on if have
A. an e4xpansion tank (twist on cap)
B. a overflow tank (flap cap/ open to atmosphere)
@@josediazasmr6014 wud only get bit water in a cylinder mainly wen cold shut off as once started may run rough clearing up once at runing temp as long as water topped up & not boiling due to low level = air/ air lock pockets = overheat. if do stop shit leak bypass heater core & entire rad if u have ability/ if not remove thermostat run till hot allow sufficient cool time reassemble. ☆JoeDog&K-9'sBuddie☆
Actually on most cares that’s part of the cooling system and it’s pressurized. Good way to tell is if the cap reads don’t open when hot that overflow is part of the system. If the cap on the bottle has no warnings on it it’s just an expansion tank.
@@joeyallcock1011 That was the toughest thing in the world to read and make heads or tails out of.
They told me it's might be the wiring.. Do you think they should touch the wiring??
What about a radiator cap failing?
Then get a new cap it’s a simple fix
Thanks for posting very helpful.
Hey brother how you doing? I have a new radiator a new thermostat and all that other stuff is new but I did raise the front part and the air gets out. Trap are and I was able to put more radiator fluid in there and it helped I think. I've changed several CO2 sensors and other sensors. Just change the air flow sensor. I hope my car starts I'm not a mechanic. Once again you and your family stay healthy brother. ✌️💙🏇🏇🏇
What about if your gauge goes to 3/4 after about 4 miles with the A/C on at 95 degrees or higher but is fine with the A/C off?
This helped greatly Thanks!!
My problem is so unique. My AC stops working. Only option to do, since all other issues are not the problem. I have replaced the thermostat several times, last time 5 months ago. I have not needed the AC, so I haven't replaced, even though the temperature gauge stops registering, but heater still works perfect, no engine over heating. I am trying to prepare for summer weather, what can it be? Is there a specific thermostat I need for a 2.2 engine? I am never asked when I buy them, which one I need. I have asked and the dealership has said only one specified. The dealers was $75 and still same problem in a few weeks. Help! Please.
I have a 06 Cayenne 3.2L v6, only starts to overheat when I go 75mph+ and it’ll go away when I slow down. But coolant reservoir blew up on me on the highway. So I replaced that. Not sure what could cause the overheating at high speeds
Hello , I’m not getting any faults on the diagnostic reading but my temperature gauge is going high .
What is that jug called exactly? To air out the system?
Can someone explain how the water pump fails. If the impeller spins how is it causing the coolant to overheat? Even if coolant is leaking out of the weep hole but the coolant level is not low what causes the overheating?
@HVACMECHANIC On my way home today my 2005 Mercury Mariner beeped and said "Hot Engine Temperature" I noticed the temperature guage was all the way on high, after I continued to drive a few miles just trying to get home from work all of sudden the truck just completely turned off right when I was about to make a turn leaving me stuck right in the middle of a busy street😢. I never got any warning prior to this so what do you feel the actual issue could be???By the way I did have my AC on and turned it off as soon as I noticed the temperature gauge was on high.
what if the coolant is leaking then stops? pulled over cuz gauge and steam indicated overheating, waited for suv to cool off, added more coolant to get home, it didnt leak that time but under hood by coolant was gettn warm again?
I just changed the thermostat. Its still overheating. Temp goes down when we open the cap to water reservoir. I think he bled it right. What do i do next. I cant afford a mechanic
Quality video!! New follower
My temps stay between 177 and 184 when the a/c is not on. Unfortunately when the a/c is on, I see the temps go up to 205. I have my radiator fans turned on all the time but even like this, the temps climb high with the a/c on. With the a/c on and at highway speeds, the temps will mostly drop to the mid 190’s depending on the outside temperature . I’m really hesitating on installing an oil cooler to assist because it just adds complexity.
Hi, I know this video is a bit old, but Iam having an overheating problem with my Subaru,
Its a 2007 1.5R Impreza ( hawkeye )
- I can drive all day at lower speeds, and have a perfectly stable temperature, but if I take the car out for a long freeway drive and hold a constant 60-70mph, after some time, it can be after 30m or even 60min the temperature will all of a sudden start to climb.. all I gotta do is to let of the trottle and slow a bit down the the temp will go back down again.
this is the second time ( second engine ) that has this happening to it, the shop told me they needed to replace the engine, and so they did, but also they replaced the radiator.
( big bill )
anyway, now after a few years after the first engine was replaced, I get the exact same problem.. the temp will go up at higher speeds after a long drive, and will cool down as soon as the speed is lowered.
Any advise ?
I have a toyota yaris 2008, facing problem of overheating when on high speed like over 80kmh and when vehicle running for long time already changed radiator and water pump,still same issue,can u enlighten me with the reason please।
I have benz E350 and it starts overheating when I turn the ac on or when I am traveling at the slow speeds or stopped completely but it stays normal on freeway even with the ac on for long distance too but if I press on gas really hard or usually traveling at slow speed it is doing that for few months now.
so my moms car always overheats when going uphill but then the temps shoots down when going level or downhill. Is this a sign of a bad coolant pump?
FINALLY an actually helpful video! Thank you
The last thing could be a small amount of combustion going into the cooling system which will cause it to do those same symptoms plus make the heater go a to warm when it's on high heat.
I have a jeep grand Cherokee 2015 3.6 my temperature rises when I step on the gas. Do you know what it can be?
Currently hunting the same problem. Only overheats on the interstate 60mph+
Flushed a bunch of rust out of the radiator system. New thermostat, New water pump, new mopar coolant. Still acting up. Also coolant temp sensor changed.
Gonna try the radiator cap and if that doest get it, flush again.
any luck i have 2015 3.6 as well. mines only overheats after a cold start and 10 mins of driving@@sk8ter202
I’d like to add #8 I was having to add a large big gulp cup every day. I couldn’t find the leak for the life of me. No drips no where. I finally started ripping out the whole front end! Out of the corner of my eye I finally see a drip… the back side of the radiator cap!
😮😂
So I got the symptoms of a air pocket in the coolant system but when my car is idle it has a ticking sound It’s nothing to loud yet but i’m having trouble diagnosing it
Hi i have a 04 wrx with an ej207, have changed out the radiator due to a hole and replaced the ect sensor also but am now have the problem where the gauge is going over 2 3rds then the fans kick in and it drops back down to under half way, the scan tool is reading the correct temp for fan activation and the temp gun is pretty close to it also, ive bled the air all out and done a pressure test, system held pressure and im not losing coolant. Any ideas?
Easy to understand. Thanks heaps
My car stay in the middle cold and hot but as soon as I start to drive it it starts to over heat any suggestions u might have I would appreciate it
Sound like you need to put a block of ice on yo shit 😂😂😂😂
My car is a Tacoma 98 and the temperature gage is on high, the car turns over but won’t turn on. Any help ?
Humm, my 2005 F150 gauge went to hot, check gauge light came on. Changed the thermostat, and it did it again. I pulled over off, and back on, and normal temp. I slowly open the reservoir and it fills and would overfill if allowed. Looks like trying temp senor next. Any opinions are appreciated. Only work truck.
Radiator cap
The best video! Thank you
My 2012 chevy equinox keep trying to run hot. Then it go to normal, pretty much keep fluctuating.. sometimes it when im in traffic and sometimes when im driving on interstate
Or leaking in-between cylinders , and giving no blown head gasket external symptoms.
It would stay hot if head gaskets read mate
@@kirra8787 not by air leaking into each cylinder.
Im pretty sure its the fan on mine, i noticed if the car is idling the overheating jumps up but once I drive it drastically goes back down in heat N stays cool, i added more coolant and got a oil change plus prior the radiator transmission n fuel injectors was flushed... so it has to be the fan, luckily i live in a colder state while driving, just damn... shit popped up 3 days ago
After changing all the parts mentioned on my 16’ sequoia, I’m at a loss. Still overheating.
Yeah my Chevy impala 2007 Lt doing dat now when I speed up it goes back too normal and level out too be honest my coolant looking corroded
Mine overheated tonight. I sat for a while it cooled down fast (30 minutes) So the resevoir was okay I didn't check the radiator tho I was afraid it, would be too hot! Then I tried to drive it. Got about a mile and bam same thing only worse. And there was no power for 100 ft as I drove it the second time...so I had to call a wrecker to go home. 😢 . what about bad head gasket does that cause it. I hope I didn't ruin my engine. There was no steam. There was no smoke. And only a trickle of antifreeze near my driver front door
I have Mazda 6 2002 year, i will drive like 15 to 20 mins even 30 mins before it will get overheat, no leakage, the temperature will go high and the car will stop and sometimes i will not add water but as soon as i on the car it start again, please what can be the problem tnx
I’m having a problem of over heating 2002 jaguar, but I was told it’s my housing unit/thermostat 500$& up work
Even though it’s made by Ford!
Great summary
