Excellent, the way you went over and listed the 7 points right off the bat,instead of dragging out with a bunch of nonsense. Gret information in this video. Thank you, good job
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!
Or radiator/expansion cap is bad.
I have a cruze with a faulty waterpump. replaced the pump and the inlet pipe blew off when driving and the car overheated and blew the head gasket. (water in the #4 cyl, and milkshake). Got some head gasket sealant and tried that and it seemed to work. (no water in cyl and no milkshake cant check compression). But now there is a intermittant overheat issue. There is no thermostat in it so it should run cool. The coolant level is fine, and it does not drop, there is no thermostat, the heater works and when it starts overheating, I put the radiator on full and the air is hot as hell. (this brings the engine back into range and then it is good for a while again). The fans work, and I dont think that it is a sensor because the air is super, super hot when it start overheating. The water pump is new,and I have flushed the system once before, but I need to try it again. .. Any other ideas please or an I down to junking the car or replacing the motor?
Seems like you have gone over most everything. Some engines do need the thermostat installed to slow the coolant to be cooled, so it may need a thermostat installed. The engine and radiator may need a flush. These are just guesses.
@HVAC_Mechanic thanks, I have the OEM thermostat so might as well do the thermostat and flush at the same time.. here is hoping
No one’s explain everything so simple and clear as this foo
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.✌️💙🏇🏇🏇
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
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.
So if my fan turn on is it a different problem?
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.
@@ryans413 thanks for your advice, I’ll have to check that out.
Very useful information. It helped me sufficiently to fix my car.
Thank you for posting it.
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.
The best video out there. Thank you for this very important video. Now I can save some money and do the work myself.
Quality video!! New follower
This video is amazing. I watched over 100 videos on various engine repair and you're the only one that gets right to the point doesn't introduce himself and talk about what we're going to do various things this and that blah blah blah. Thank you so much for getting right to the point speaking clearly concisely. Short and sweet. I wish more videos were like this. Thank you very much for your help
Great information. Two thumbs up!
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
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.
Nothing worse when that comes down looking for water
My trusty 5gal jug
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.
Great video! You done an awesome job explaining it all.
lol thermostat on a Chevy Colorado is $130. Ridiculously High. Also a pain to change. The design engineers obviously don’t work on their own vehicles
Hello brother, I’ve noticed some Colorados and Hummers share the same parts.(they have the same 3.7l engine) You should research and see if a 08 Hummer has the same thermostat. They’re only $20-$60 on Rockauto! Best of luck!!
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!
😮😂
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.
Mine does this as well
@@ItsJ4KE Mine too. Did you figure out the issue?
@@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.
Thanks for posting very helpful.
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 👍
Did you find the problem?
same exact problem here. Hope someone has some insight
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.
To the point and on point with everything. New subscriber keep em coming.
very informative video, thanks
my jeep liberty runs normal temp when parked, when i drive the temp goes up quickly. after thermostat change, also seem to be adding a-lot of fluid but don’t know where its going. oil looks good
Using more coolant because thermostat operating properly..
This helped greatly Thanks!!
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’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?
Just painting simple he couldn't have explained it any better than that good job
Mechanics have been known to place thermostats in place upside down . Cylinder head gaskets that fail may cause these symptoms .
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.
But if the car has problems with Thermostat ,you get check Engine ..
only on cars that have check lights, check fuses, and only if thermostat is real bad will the light come on in some cases.
@@georgegouvas27 ..Hi thanks for your kind reply , i changed my Hummer 3 engine a few years ago [ then i kept in the Storage somewhere after a few months of engine change ] , but i saw the Gauge is moving upward as the engine warms up , i told the Mechanic who did the Engine change and he said don't worry !!
Anyway, when he installed the Engine and we were ready to start the engine i was in the garage and behind the wheels and as i started the engine and he was in front of the car the Gauge of engine Heat jumped to the highest point , then he manipulated some Wiring of the engine [ the wiring for the Coils and the Gauge dropped to much lower level !! ..
So i am Wondering what must be Wrong , and if change the Thermostat , or the Sensor for radiator , or maybe it is a Water Pump issues , or the Fan Clutch , or and internal Engine issues , the Fans are working well ..so i am so worried what might be the cause ?
The car is still in the storage , for about 2 years of even 3 years ...
I used synthetic oil and new filter before storage , do i need to change the Engine oil and the Oil filter for long term storage or it does not matter ?
Thank you if you can answer all these Questions ..
Great video! Very informative. Thank you.
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
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.
your great bud thank you for solutions so clear cut and to point no bull again so appreciate you
clear explanation !! thank you !!
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.
one other reason would be a short in the wires giving mixed signals to the computer.
Thanks for your tips! I've tried everything!!
did it work for you??
I sold my 99 jeep Grand Cherokee for 400 dollars because I couldn't get it to stop overheating. Wouldn't take it back for free. Damn jeeps
Thanks video helps 🎉
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
Appreciate it the way you clearly explained. Everything really helps us make a decision whether to replace a thermostat or not.
Thank you for this🙌🏻
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।
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.
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
with this intermittent heat problem... Can you now rule out a blown HEAD GASKET ?
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.
Temperature light comes on when I go upa slanted hill. And hills. Not on flat surfaces. 2010 prius
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
Great summary
What about a radiator cap failing?
Then get a new cap it’s a simple fix
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.
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?
Thank you for all the insite
GM thermostat for a Cobalt $135.
Ty so much!
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?
my god mechanics are so often fucking hacks, so frustrating
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
Super valuable video
Easy to understand. Thanks heaps
My engine overheats while climing hills ŵith or without AC but the gage go down as we go down hill.
Could be a clogged radiator where the coolant can't work its way through the core.
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
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.
A lazy thermostat can cause this also!!
My overheat indicator only goes up when I turn on the AC. Without the AC on, it does not show overheating. What is causing this?
Some leakage in cooling system..
Great video
Good video bro.
thanks
Thank u
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
@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.
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.
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
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.❤
So I already replaced the thermostat, the sensor, waterpump, coolant reservoir and even the coolant housing, idk what else it could be
Maybe the Radiator
@@tieshamayfield216 imma change it, but what my car does is that im driving and its fine and then overheats out of nowhere and if i keep driving and ignore it, it goes back to normal
@@servero888 did you find the problem?
@@sa3much not yet, i took it to a mechanic and he said it might be the head gaskets but im not losing coolant, and there’s no milky fluid in the oil so in not so sure bout it
@@servero888 Yk the same thing is happening to me, my guy also said head gasket is beginning to fail, but I have no symptoms of that. I have a 2013 Nissan maxima
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.
Mine nearly (I never let it get to red zone) overheats according to the needle, when the ac is on after a few minutes. No issues when it's on hot. Anyone know what it could possible be? I know it's not the fans, plenty of coolant is available, no smoke from under the hood, oil looks normal, car sounds normal, no knocking, loud noises or anything. I don't believe it was an air bubble.
Hi I have a Subaru Outback 2010 the light for overheat is flashing when I am driving the car when I stop It stop blinking continuing driving flashing start flashing again
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
You’re awesome man
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'm not sure if the radiator fan turns on while the car is running but it turns on after the car is off, I changed my thermostat, temperature sensor and now I'm going to flush out the coolant, I don't know much about cars 😂😂 but I'm having fun learning if you could please give me some idea's I would greatly appreciate it 😅😅😂
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 300 chrysler 2.7, overheated, dash gauge dropped, reservoir boiling and my car stalled, have a new thermostat on it, all go and check cap and look for leaks, its making a pinging noise, the auto part code said thermostat! Man, am so sad! She my baby! I thought it was a creature stuck in my fan! But nope!
Also the bad radiator cap , radiator fan control module, relays , fuses , worse case scenario head gasket ….note : to Chrysler dodge owners ….water pump thermostat housing and oil pump are plastic known to break or fail ….they do make upgraded metal oem replacements …if your willing to spend the money 💵…because being a penny pincher will hurt your budget long term having to constantly replace the plastic parts or worse ruin your engine ….these days we need our vehicles ….so think smart ….little by little maintenance these parts can be replaced ….you don’t have to do it all at once …my current situation is with my 2018 dodge grand caravan gt e85 flex fuel super charged …lol lmmfao rolmmfao aaaah hahahahaa….so it’s my water pump oil pump thermostat and housing and radiator fan …no codes pop up ….all my fuses relays modules connections are great …
The antifreeze just pours out of Reservoir comes right out H...E...L...P!!!!
Why would my 2015 Mercedez show hot and I pull over and 3 minutes later shows normal. And doesn't heat up at slow speeds-only on hiway speeds. Coolant is at a normal level
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?
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
I have a Nissan Almera. The temperature indicator goes on to red even after changing the cooling...
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
Can they do your wiring?? Mine does this, changed the switch but still the temp indicator goes to the red and back to normal
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?
Hello , I’m not getting any faults on the diagnostic reading but my temperature gauge is going high .
3:20 Lmao I love how I'm trying to find the cause of the problem for a BMW and the picture is of the same year and series bmw 😂
