How To Solve An Engine Overheat Condition - EricTheCarGuy

[@XROLMAN]

I'll be honest, I don't understand the 248 thumbs down. For such a simple seeming topic Eric shows how there is much more that can be involved. This is one of the most complete coverages of a topic I have seen. Granted it seems like a boring topic, but Eric brings out all the possible causes of an overheat condition. He explains how to troubleshoot the problem and shows how to develop a thought process for troubleshooting. I was troubleshooter on computer system for 30+ years so I respect someone who not only can troubleshoot but who has the ability to explain it all. Your communication skills are outstanding Eric. Hats off from an old troubleshooter.

[@MrFeyerwire]

I suspect that the 248 thumbs down are from haters or other mechanics who are angry at Eric for demonstrating their trade craft. I understand that mechanics need to make a living and they still do, a majority of jobs are far to complex or require too many specialized tools for your average DIY to do themselves. I recently paid to have my trucks fuel pump diagnosed and taken care of. I think that mechanics need to realize that sometimes, paying 800-1000$ to fix a car, is not an option and doing nothing means the difference between taking the buss to work or driving to work and a lot of people cannot take the bus to work, because no routes run near them. I didn't have any sort of father around to teach me how to work on cars when I was younger and I definitely didn't have any money to pay a mechanic, I learned the hard way ...... using cryptic Chilton's & Haynes auto manuals ..... if only I had access to these videos when I was younger.

[@machiavellian18]

That’s funny, I’ve been learning about cars lately to fix mine and I was thinking how it’s like troubleshooting a computer and fixing the broken parts. It’s not exactly the same but it’s the same feel ,how one problem can lead to another.

[@JohnnyMacalvee-cf7et]

I see that some mechanics don't like this that Eric gives tips. I get it. It is really simple. There are two types of people. People that will just send their car to a mechanic...that is fine, and the good mechanics will ALWAYS continue to get business. Half the time, I am that person. Then there are the other types...people that have cars and want to learn and that is where Eric comes in. Educating the video watcher. Not everyone has the money to do simple DIY actions. However, I would take my car to Eric if I had the money and/or don't have the time. Eric is fantastic. Case closed. The point don't worry mechanics...you will still get business from me and others.

Thank you, Eric. I am having a PT Cruiser overheating problem for a second time. The first time was just over a year ago when a company that repairs only Dodge and Chrysler attended to the problem. They replaced the water pump, all belts, thermostat and radiator cap. So, now that I have an overheating problem again, I decided to take steps myself to fully understand the causes and solutions. I have seen several KZbin videos but did not find any that covers the topic so comprehensively as you have done. I now feel more confident at least to find out the cause of the over heating. Your video offering is much appreciated.

My car didn't over heat many years ago, but it would have and now I know why. Bad radiator cap. When warm, it'd go to the overflow, but it wouldn't come back so I kept having to get rid of air bubbles, but never succeeded. So glad for the radiator cap info too!

Truly intelligent dude and such a well put together segment!! I followed along start to finish and understood all of it! :D

[@jawojnicki]

Last time I posted on this video was 12 years ago! Eric does an outstanding job of explaining the principles of how relays work and how to properly test them in this video. BUT, for people who are a little more advanced electrically, a much simpler way to test the relays is if you have another relay in the fuse box that's identical to the one for the radiator fan, just swap the relay with the other one. This will take you one minute at most. If the fans now work and the circuit that you pulled the other good relay from (headlight, etc) doesn't work anymore, you've nailed the problem and your diagnosis is done. Under 5 minutes and DONE! If the fan still don't work, and the other circuit does, you know that the relay was good all along. Also, activate the fans and tap the motor with a long screw driver. If it starts spinning, the motor has a broken winding. 30 seconds and diagnosis is DONE! Understanding systematic diagnostic procedures is really super important if you are new to this, but as you advance, you want to start using these much faster procedures to get the problem fixed sooner!

[@timmyneeley3913]

Thank you Eric. I watched this video after my '05 V-6 Mustang was over heating at stops and Idle; this after just paying $500.00 to have a new radiator put in. Your video caused me to examine the fan. Low and behold the mechanic forgot to plug the fan back in. Thank you.

Radiator cap was causing my overflow tank to bubble alot due to broken rubber seal letting air prematurely escape the radiator. It didn't become an overheating problem until I tried to take a longer road trip and thought to check the radiator cap. Good stuff. My mechanic recently did my oil pump and water pump but forgot to put a new thermostat. Based on what you said I'm sure it's starting to fail it's easy enough to change great info

[@stephenscheppele6169]

Excellent video! There are a couple of other things that can cause overheating, but this video covers the most common causes very well. My diesel motorhome over heating was caused by a loose radiator hose that allowed air to be sucked into the coolant, but didn't allow coolant to leak out. I also had a bad head gasket on the air compressor that caused air into the system but didn't allow water to leak out. Go figure! Excellent video!! The pressure test shown found my loose hose. One more thing, the liquid used in the tester for combustion leaks comes in two different types, one for gas engines and one for diesels. Use the appropriate fluid.

[@charissedecalongne2553]

Just wanted to thank you for everything you do. Really helps out, yesterday I had a company that comes to you, cost less than a brick building. Had an over heat with my 2006 Chevy Express cutaway 6.0, when I was getting y transmission serviced that told me that he though that the fan cutch was making noise. OK got OME replacement had my guy come out and change it plus some other front end work like tie rods ends etc. Got home to pay him and "oh your water pump is leaking" and he had to go. Ok this would be the 3rd water pump in 3 years, got a OME replacement pump. After I got back to pay him again he looked worried, van was over heating just sitting in the driveway, so after lots of chat I said lets change the therm o stat, he was looking like I was nuts, So I know his boss was rushing him to go to next job. I told him that back in the late 60's we would just pull the stat out and forget it. Does not snow much in Florida, question without the stat the engine is running about 20 degrees cooler, how important would it be to replace the stat? using 1 to 10 where would that be ?

On small correction on how a thermostat opens - there is wax in the copper colored capsule that expands when heated and opens the valve to allow coolant to go the the upper tank of the radiator. The spring closes the valve. Good video - very practical.

Thanks Eric. My car gets too hot too soon in heavy traffic. My mechanic checked it out thoroughly and said everything was working like it is supposed to. His advice was to run the a/c on low so I could keep those fans turning. I had not been doing that for fear that it would overload the engine and make the problem worse. Thanks for verifying his advice.

[@norval82]

I cannot believe I just watched an auto repair video but I did. I was interested in the subject matter because of the over heating coolant warning in my 2015 Dodge Durango, but also because of how you articulated possibly diagnostic. After numerous trips back to the dealership, and they paying out thousands in loaner cars or rentals they still cannot resolve the issue. I want them to take back the vehicle at this point. A new vehicle with less than 18K miles should not be having these issues. Thanks Eric!!

[@jimpolk2987]

Great vid...thanks Eric. Only topics missed I noted were check to verify if the thermal switch was possibly malfunctioning (preventing fan from being energized) and any reference to possibly having a water pump mechanical failure or otherwise some type of restriction preventing flow of coolant thru the radiator. That coolant in the video was clogged full of all kinds of nasty chunky debris. Also imagine its important to mention whether or not the coolant has proper percentage of anti-freeze as that also dramatically affects the boiling point of the coolant similar to how you described the importance of the radiator cap. There's cheap testers for verifying the anti-freeze is proper mix ratio. Not sure what is out there for testing if the waterpump is poorly pushing fluid (if say vanes corroded or broken) or if radiator is clogged from debris (like the mess that was seen in your vid) other than trying to run radiator at temp without cap to see if you can detect flow in the radiator. Observing bubbles in the radiator while running also good visual test for head gasket failure though your gas detector kit is better measurement tool. Thanks for the ideas...helpful for me as I'm trying to track down son's coolant problem in his '01 Civic.

[@d-railed3917]

Jim Polk I was hoping for some of the same information Jim

[@mwj5368]

Hi Jim! I'm soon to go to a pro shop that advertises they work on Subarus. They said for $75 they have a special testing technology that pumps air into the coolant system to see where in the whole of the system, I guess many possible areas, where coolant can leak. Have you heard of that? What kind of technology is that? They said that test is the ultimate to really know why my car overheats. I already know the 2 fans work. The upper radiator hose collapsed and the mechanic that a few days ago changed to new fluid and was suppose to get all the trapped air out from when a guy who had put in a new thermostat. He also did the blue dye test and found no head gasket leak. I returned by luck for something forgotten plus still sound of air under dash. We found upper radiator hose collapsed. He loosened the hose clamp and let air expand it again (only I thought "oh no, he's letting air in the system again) and said top it off into radiator once all is cool and keep doing that until all the air is out. He was suppose to bleed it all out, the reason I brought my car to him to begin with. Also topping it off had already never worked before as another shop had told me to do that too. Just wondering I guess what that special testing device is. Have you hear of it. Also, what might be my overheating problem? I was thinking it was because it was never properly bled after the thermostat was put in. Thanks!

[@d-railed3917]

mwj5368 Try a new radiator cap.

[@mwj5368]

Hi Darrel! Thanks for the advice! I before receiving this yesterday bought about an $11 cap with what they said has a safety release lever so you don't get hot fluid on your hands, yet I read on the cap and only looks like it's some kind of a lock, is that what those levers really are, just a lock? There was no description with the cap. I drove about 18 miles with new hopes and parked. All went find but when I looked the reservoir bottle was full to the very top! I let it cool down for 35 minutes. The temp was 38 degrees. I then drove 5 miles toward home. On the way the cabin heat on full blast would go from very hot to outside temp just randomly. At 5 miles it went into I think "air-lock" and over heated. I stopped for 25 minutes. Once cool I added 1/2 gallon of coolant direct into the radiator! The reservoir was full to the very top. With my flashlight the lower radiator hose looked bulged, but like the upper hose only a 2yr old hose. The $17 thermostat (just were lower radiator hose connects on a '97 Subaru Legacy L wagon and it was only 2 days old. Also the upper hose was empty and hot. I drove another 12 miles home at 65mph yet 2 times the temp needle started moving up then went back down on its own. Do you know what all that means? Thanks! Oh, have you heard of that technology that pumps air into the cooling system to locate problems? It will cost $75. I'm thinking of going to a junk yard and bringing a used radiator to my appointment on Wed 11-1-17. I spent about $2,000 on it last spring through a home garage mechanic. I now learned never spend more than the car is worth if you were to sell it. Have you heard of that?

Too bad all mechanics aren't like Eric and give a damn.

[@srussert28]

Craziest thing I have ever found to be cause of overheating. The block was half full of sediment. I added a double dose of super-flush the system ran it twice as long as the minimum required. I started the truck and did the flush till it came out crystal clear. I then drove around on the highway that circles the city. Roughly 30 miles at 65 (+)MPH with another double dose of super flush. I modified a flush unit with a ball valve so I could attach a garden hose to the heater hose while the truck was running under pressure and hot. I then did another flush till it cam out crystal clear. Now that everything was clean I replaced the radiator, hoses. thermostat and all the little things needed. The cleaning opened up a small leak in one of the freeze plugs.I drove it a while and it still overheated. When I popped out the freeze plug there was sediment almost to the top of them. I took out all the freeze plugs and ran a garden hose with a pressure nozzle and a wet dry vacuum. I pulled out about 3 quarts of sediment. The bottom of the cylinders were packed with sediment so the water couldn't circulate causing the coolant to boil. If the flushing hadn't caused the freeze plug to leak This would have taken a lot longer to find. I don't understand how that much sediment filled the block

[@petermensing5502]

Yes. I have encountered this over the 40 years I have been an ASE Certified Tech. Although a significant amount of sediment can accumulate, you are correct that not that much sediment would collect (presuming that the system had coolant in it and not just straight water). I have found the culprit is what was at one time the temporary cure for radiator leaks. A product of powdered metallic called Stop Leak. Whatever metallic powder product is not used to seal up a leak in a radiator or freeze plug that was leaking will eventually wind up in two places. The first spot is it collects in the block at the bottom of the water jackets. Secondly and somewhat equally, it will collect in the bottom of the radiator. Eventually after repeated and almost habitual use, the water jacket fills up with the product combined with sediment and basically shrinks the engines cooling jackets to the point where I have seen the product clear up to the cylinder heads, and the block was left with nearly no circulation at all. It just goes to show you that the quick fix is exactly and only just that, and can cause greater problems with continued use.

I really appreciate you taking the time to produce these helpful videos. When my car is overheating, I immediately check the oil. If it looks like chocolate milk, that’s coolant in the motor. Here’s a tip. When I’m going to buy a used car, the first thing I inspect is under the oil filler cap. If I see a jelly goo like substance, I walk away from the car. That means the car has overheated and cooling fluid was in the motor.

I agree, I was expecting Eric to say something about the water pump, but I believe to test that, you can just turn on the heat in your car, if it blows hot, water pump is most likely good…I think ;-)

[@charlesfazio2015]

Eric.... I really appreciate your logical systematic troubleshooting... Wish i had u for my mechanic... God Bless

[@TheKurtabryan]

Eric the car guy is exactly what a lay person needed to resolve my problem. Learned so many other things as well, which is a bonus. Thanks bro. I owe you a HJ or BJ, no expiration so hit me up when you need it.

[@LAWNPRO]

GREAT VIDEO OF COURSE ALL YOUR VIDEOS ARE GREAT LEARN A LOT VERY COMPLETE YOU ARE THE MAN!!! I MEAN THE CAR GUY :-)

[@louispuglisi9867]

I think you forgot to mention the temperature sensor that controls the relay that controls the fan

[@Pishuriz]

Hi Louis puglisi, That was what I was concerned about. Because I changed out the hoses that were bad & I recharged w/refrigerant then in 1 week no air came out the vents so all I could figure out was that the temperature control sensor was bad. Am I right? Cuz the gauges show hot but it's not hot at all irs normal hot temp. What u think?

[@massesbulet]

I have oldsmobile cutlass ciera 1994 3.1 I changed the coolant thermostas hoses and rad cap but when car idle or stop on traffic for long the temperature gauge will pass the half and fan is working but its kicking on late is that the coolant temperature sensor

[@gregbishop7750]

@@massesbulet , from your description and assuming you performed Eric's checks then I would try doing a radiator flush. It is possible the 26 year old radiator (if it is original) is plugged up from internal rust and corrosion therefore losing efficiency so it doesn't cool properly until you start moving forward to get more air across the radiators remaining usable (unplugged) space. Be warned, sometimes with a really corroded radiator once the rust and particulates are flushed out you may find a leak that was not there previously. Better to find it at home doing a flush than out on the highway.

Yes . probably thas is why the 916👎 . I liked this video and I clicked 👍.

For the layman auto mechanic, Eric, the proper term for that "upside-down horse-shoe-looking thing" is the Greek letter capital omega. it stands for the electrical/electronic word "ohm" or "ohms."

I have to say it, most likely I have before...but whatever. I freaking LOVE your videos! I have learned SO MUCH about fixing my cars, especially my Honda by watching you. I have been subscribed for years. You explain everything clearly, with direction that is easy to understand..plus you give great tips. I always check out your videos first if they apply to the issue I am having. THANK YOU!

[@moisesymaria]

Loved the video... :) Just a question, could you fix mines? You make it sound simple enough for a female. Thank you!

[@barillamindset3109]

Mines? He is a car repair man. Why would you need to repair a mine? The explosive kind is too dangerous to repair and likely needs to be completely de activated and destroyed. A gold or diamond mine would be a completely different type of repair job than an automobile.

[@RizwanAnwarAKAFLYTIGER]

thank you for your videos sir, youre a legend :)

[@zxKrookedxz]

Omg if I’m on the highway or driving for a long time without stopping it’ll overheat but if I️ stop it’ll cool down

[@adrianqx]

Great vid, should have also mentioned a faulty water pump and also a faulty alternator can cause overheating if the bearing are worn and stuck !

[@leereader3725]

I am just a regular Joe and I have to tell anyone pissing with coolant and radiators you must buy a "spill free funnel" it will help you soooooo much it makes this situation so easy I look forward to using it, it helped me find I had a blown head gasket, it also help with replacing block heater plug, water pump, thermostat and fluid change it help bleeding air easy peasy!!!!

[@stefanosstamatiadis740]

Heater trick literally saved my life. Driving downtown with wife pregnant, and cooling fans failed...

Come to Oahu and look at my car. I'll pay you $500. Lol. No really. I'm so done. Overheating. Big mess.

Virginia Francis hi virginia how are you,what car do you have and whats the problem, i wish i was in hawaii again to help you, i used to be stationed in oahu, i actually raced stock cars out in ewa beach, cambell industrial park before it closed.

[@SLIvista]

Virginia Francis bad water pump, bad thermostat, old fluid, air in system.

[@mystarhawaii]

hey! we live on Oahu too and would love to see him also! Maybe if we get enough people together we could pick up the tab for his ticket! Wouldn't that be a great business trip he & could write off? He is such a nice guy and just like the local guys here that try to help when they can.We have an Isuzu 2008 pickup that over heats and can't even find the darn Thermostat to change it! Supposedly same as the Chevy Coronado but I Dunno!?

[@evdaribarovski5698]

I enjoyed listening to your video learned heaps my car is overheating and it might not be just the thermostat. I just hope it's not the head gasket. It happened suddenly. About a month ago. I hope it's nothing major.

[@lazarotamargo8110]

Thanks Eric. I have a 2006 Nissan Altima 3.5. that only raises the temperature gauge to almost max when I travel up hills. I'm gonna do what you said in this video. I will check back if I can diagnos the problem. Thanks for your great info. Your very thorough and knowledgeable.

A head gasket for my civic costs more than a motor from hmotors.

[@michaeladsit6721]

Awesome job explaining in a simple straightforward manner! This is probably been commenting on but I didn't hear any comments regarding water pump failure such as the impeller breaking which I had happen once. Highly recommend

[@kenamesthewatcherchronicle6746]

Great video. It saved me $800. I figured out that the radiator cap valve was bad. It was bleeding into the reservoir but not sucking back into the radiator. A mechanic tried to tell me I needed a head gasket changed and was going to charge me $800.

[@fgbowen]

(7:23) - I have a 2011 Dodge GC. The coolant temp rises when the AC is on, but scales back when AC is off. AC on - Temp fluctuates 219 to 224+ (rarely to 230 - and rarely down to 213) - stays at an average of 222 most of the time. I thought perhaps it needed coolant. I put some in. And right now it's idling. The temp is fluctuating 212 to 219 - (but again, it's just idling). A few days back, the vehicle had a hose blow, and my usual mechanic found the leak (gaping hole) - This was fixed. But now today, this. It's Sunday night. I'll take it back Monday to get it checked. Your video here is excellent.

[@chi-townvenom3364]

great video Eric I also wanted to add another over heating problem that's over looked that would be the water pump I've seen water pump's fail and cause over heating. I did every procedures you talked about on your video then I thought about checking the water pump took it apart found out it was free wheeling and it wasn't spinning the fins besides that your doing a great job keep up the good work.

[@michaelbeilsmith794]

Great informational video. FYI Explorers and Mountaineers 2006-2010 have a cooling system operating pressure of 20psi. Results in a lot of radiator failures.

[@tomctutor]

Thankyou Eric I have an overheating Lexus diesel on the highway and have both the pressure test kit and CO2 analyzer kit. My fans come on when A/C activated, thermostat appears ok as the radiator hoses hot and pressure up. The car runs ok for a while at correct temp, only after a while does it overheat! Oh and oil is clean with no white exhaust smokeI I suspect head gasket or block issues so we will see. Your video was excellent in detail explanation and method to diagnose so grateful for the time and effort you put into this. Fascinating how you have a car there with almost everything gone wrong in the cooling chain?

[@johnpavon799]

Great video, I would add the choice of Thermostats is important "Slant" is making ones without a release valve on the upper section. "Do not purchase those" get the ones with the release valve on the upper section and install properly so the air can be released from the release valve.

[@javierrmejia]

I wonder why i didn't see this video before my totally useless change of the ECT Sensor, thanks Eric for the tip of the hoses temperature, I found that the problem is the termostat. You Rock. Javier from Argentina, Civic 2007.

[@Jess88176]

Awesome video Eric. Thanks for all the info. I had no idea the radiator cap was a little machine. I just wanted to throw out good circulation of coolant through the system. Another big player in the overheating game. Sometimes a good flush is what she needs ✌️

[@rockettcrawford890]

Great video. Learned a few things and thanks for making this available. Someone can quickly check for a broken fan belt or as you implied anything leaking such as a hose or the water pump. If the water pump bearing is bad but it's not leaking, I'd be curious of a way to check this without removing the pump. I'm guessing the bleeding wouldn't work very well without the pump working or maybe the fluid can be seen moving with the radiator cap off and after the thermostat has opened up?

[@davidscott5903]

Mine was bubbling in the expansion chamber, so it was a head gasket. I wouldn't normally use stop leak, but the car already had 240,000 miles on it, and just had to last us a couple more months, so I used the stop leak for head gaskets, and it has almost been a year without any more problems. I am amazed that it worked, but am glad that I won't be rebuilding the engine with that mess in it.

[@titansuprruda2457]

Great and informative video. Just two things that were not mentioned, and have a direct effect on overheating, are the Water Pump and a clogged or bad Heating Core.

[@richardoforiakuamoah2169]

Many thanks for this information. i purchased a very beautiful xk8 and its been parked for over 3 years due to overheating problem.i love the car so much that i dont want to sell it.this information has been very useful to me so many thanks Eric
