[@elisa2309]

Thank you for this video!! You just explained to me what the mechanic couldn't, wouldn't even give me the time of the day. And clearly what he said was wrong anyway. My engine light came on, and this is the code I got. The mechanic said that my engine will overheat. I told them that the gauge seems fine, it's not high or low. I asked questions and they seemed bothered by it. They told me to replace the thermostat, the coolant and the sensor just in case, quoted me a big amount. From your video, I have 3 symptoms of stuck open thermostat, not closed as they said. At least I know what is happening. And I'll def have to find a different mechanic...🤦🏻‍♀️

[@ubaidshahid5932]

Why Is My Smoke Alarm Chirping? A hard-wired smoke detector usually chirps for one of three reasons: 1) A dead or low battery... ...your detector alerts you with a chirp that it’s running low. Replacing the battery solves the problem. 🤣

Question: my honda civic 2012 doesn't have any engine light still it takes roughly around 4 5 minutes to get back to 1000/800 from 1500 rpm at cold start which is way longer compared to any toyota I have driven, since it has no ligh in engine what might be the caus

[@saula3726]

Idk what my Colorado 2015 has the temp gauge keeps going up and down and I have no heater inside the truck. It just started acting like that after I changed the radiator,thermostat,and water pump,and the temperature sensor. Idk what can be the problem

[@SenpachiKenpai]

What about if your temp gauge rises to just below the halfway point pretty quickly on start up but then just stays there?

[@Justjack613]

What does it mean when the top hose is seriously hot and the lower hose is cool or luke warm?

[@GweGwe-lu9ob]

Can it also cause the temp gauge to go up and down randomly

[@MilwaukeeMade1995]

So doing some research because car was starting to overheat this past monday, just yesturday i got a radiator fan thinking this would solve the problem. It did how ever on my dash it shows the Transmission running a little hotter than usual past the halfway mark on the temp gauge. Im gonna keep an eye on the engine for a few days since it did sit for a total of three days.

People love replacing perfectly working thermostats for perfectly working thermostats.

[@BlissReality]

No people love their car working which is what they thought would happen when they took their car to your shop to get their thermostat replaced, either you charged it for it, knowing it wasn’t that or your a shit mechanic who half asses his job and worries about the problems later. No need to p o s human, just let them know they wasted money and it wasn’t the thermostat but if they’d like you could still replace it 😁 then everyone happy, because if they still wanna be dumb they have the option, but punishing people who made a simple miss judgement is wrong, you already know they do shit like that because of mechanics, you think people really wanna buy the part then wait for it to show up then take it to the shop… obviously not unless your modifying your car but most people are just trying to get it to run optimally

quite frankly the easiest explanation i have found on entire internet easy to understand thank you!!!! my engine is not getting warm ( max 50 degrees celcius) collant level all good top hose is hot bottom is cold. while driving along journey i stop at a mechanic because of leakage.. but he said he disconnected a hose so i can continue my way long journey back home... now i have no heating in car ( only cold air)..... and cold engine no matted how the distance i drive...... Would it be also the EGR thermostat valve?? i dont have EBD reader but i have the engine signal ON and i morning startup usually have white smoke and also when i accelerate.... what you reckon @easyautofix? thank you in advance to you and other who read me!

Question... What if car temp goes up at a idle, then goes back down only when car is in motion above 20 miles an hour... I was stuck in a car line picking up some stuff and my car temperature shop all the way up, then and as soon as I was able to get going again came back down to normal... Is that a thermostat issue or is that something totally different... And thank you for your time and doing this vid

[@TwitchRadio]

@@kristinb5429 yeah the temp sensor was bad I assume because my problem went away after that it also helped make my car perform a little better if that makes any sense.. overall better Mpg.. but I did have a light come on again and I believe it's the spark plugs looking up how to take apart this beast in order to work on it

[@macknumber9]

Can you have both problems with a bad thermostat? My engine this morning took unusually long to warm up and reach normal operating temps and then after it warmed up it ended up overheating...

[@ironcascade7921]

Same issue here, could be the thermostat, lmk how it goes with tours

[@-Dwight-Schrute]

Could be a bad water pump too. No circulation means it won't flow through a good or bad thermostat. You will also have a really hot hose vs a cooler hose.

I have none of the details you said, the coolant reservoir is shooting it out. The car does not over heat, the heat and a/c work fine, the hoses are the same temperature and both are soft . The temperature gauge does fluctuate from a quarter to the half mark, never above that. Anything that pops to mind on what else it could be?

[@allenwebster6329]

Every vehicle I've worked on the thermostat is located on the top of the engine so therefore you will more than likely find the thermostat by following the top radiator hose, I'm not sure what vehicle you're speaking about but I believe you should not have said lower hose normally its located on the top of most engines made,

[@tequilasunrise950]

I have a 2004 dodge intrepid 2.7. It's located under the alternator

[@allenwebster6329]

@@tequilasunrise950 yes that is correct, going back to what i mentioned before most thermostats will be located towards the top of the engine the alternator is fairly close to the top of the engine and as i stated before you can follow you top radiator hose and 99.999% of the time it will be at the end of the hose ,that will be the locación of the thermostat i have a 01 sport my thermostat is located right by my alternator the reason thermostats are located towards the top of the engine is so it will be able to bleed air out of the cooling system so the vehicle has Space for the coolant and the vehicle inturn will not overheat

Can a new thermostat go bad. I had just put a new one in my 2012 jeep wrangler a week ago and a new radiator. Yesterday we drove 2 hours no problems. Well we was pickig up our son at work i left thee jeep on it spit out transmission fluid this morning took my wife to work and it overheated just smoked for maybe 10 seconds and stoppped. I didnt see any transmission fluid like last night or antifreeze. I grabbed the top hose it was warm i didnt check the thermostat hose but the radiator cap was not hot at all whish it had been before. Someone said might be the new thermostat just went bad what do you think about it? Great video and i subscribed

[@GoldenLegionHoney]

My 2015 Escalades fan was constantly on, AC not working well, engine light on and pulling that code. Replaced thermostat and cleared codes. I was also having an issue with towing where i was towing a 3k lb trailer and when i got to my location the engine wouldn't start again and is blowing the towing fuses. not sure if they are linked but maybe engine was getting way too hot because of the thermostat? We will see.

While the engine is warming up there should only be one hose that is hot. Once the engine warms up both hoses will be hot.

1:34 doesn’t it flow the other way…that is from engine is to the UPPER and through heat exchanger (“radiator”) down to the lower hose and back into the engine?

No, from the thermostat housing it will go into the radiator and cooler coolant will come out the top on the other side.

The only thing I disagree with you is that majority of the time a thermostat is found if you follow the upper radiator hose to the engine and not the lower hose.

I’m having a similar issue with my 2013 fusion 1.6. It’s about 50 degrees here in arizona and I’ll do a cold start and in about 15 mins my cooling fans will turn on and my temp gauge will spike up and get close to the redline. If I drive around the cooling fans turn off and the temp will go back down to normal (a bit below the middle mark). If I make a stop for a few minutes, the cooling fans will turn back on and repeat the overheating shown on the temp gauge. There’s also no check engine or codes. What do you think it is?
