What if both hoses are hot and fan is continuously running? Also no codes. I have a 98 avalon
I have no heat.could it be the thermostat.just got radiator flush and heater core
That smoke detector in the background is perfection.
Or a 9v it can be used to stop the beeping in your house lol
😂🤣🤣
🤣
Bruh ain’t no one out here changing batteries until they stop beeping
I thought it was mine for a minute lmao
@@anthonyhelfert9852 I kept hearing it and kept getting up and going to each room to find the culprit. It finally dawned on me that I'm an idiot.
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...🤦🏻♀️
Keep making these videos brother u describe the problems more clearly than some guys who just mostly do the changes without description of the process
Best video on thermostats. Great job. Thank you.
Best video on thermostats!!! I checked bottom hose an it wasn't hot ! Signs of a bad thermostat 💯👌 well done sir
very nice, thank you!
I have a good thermostat still not hot
Perfectly explained.
Thank u very informative and helpful!
Super informative.
Thanks great presentation n information 👍
It was the hot side and cold side that gave me the answer I needed. Thank you
Put a battery in that smoke alarm, then do a video on it.
You’re a boss! Im doing a main seal gasket replacement on my 91 ls400 and wanted to know the symptoms
I have cel and temp in ac not working along with overheating! Learned a few new things
Never had to do these, just all the other maintenance
Quick Question, my car over heats when i stop at stop lights and stuff...thermostat issue? and then I hear a kind of squeak noise from my coolant reservoir when I brake. any clue? idk nothing about cars.
@@slimjimmy3334I have same problem when stopping at lights. Did you find out?
@@juanferosle took it to firestone and it was a oil housing unit making the squeak noise... It Definitely helped it stop over heating real bad but now it comes up just a bit when i stop at a light for a few (after its at normal temp for a bit) but then i drive and it goes back down.
Thanks for the video exactly what I needed to hear right at the end can it be leaking right from the thermostat itself
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!
Great vid. Explanations were excellent!
Yeh, I really like your clips so helpful knowledge. Thanks a lot. Hope you do more clips to service cars DIY.
Thank you for this video
You sir get a like and comment because you taught me something
Many people thinks that this is a ordinary part. But caution, it's a very important part for better function as described in the video. It also uses in almost all water cooled engines.
Great video. Explains right on
This is a great video!!!
Thanks for this bro!
Goodman, thank you!
very descriptive thank you
Thank you!
Good walk through presentation! Very helpful.
Spectacular! Thank you!
Did you guys ever have that "Soup Kitchen" in the Prius?? Asking for a friend.
Thanks 4 good info!!!
Thanks man! Good info!
I appreciate you, thanks!
Great advise brother but please replace the battery in that smoke detector. It's really loud on my end... thanks again.
Very nice thank you ! and of course.
Had me looking around my room!
Awesome video! Quick question, do you know if some cars won't start with a stuck thermostat? I'm trying to find a culprit 😅
Great video thank you
Good video. Sometimes we forget to K.I.S.S. it (Keep It Simple Stupid) and can quickly turn to a major repair with no fix, or chasing our tails. Thanks.
Thank you buddy good video 👍🔥💯
I love how simple you made this for a rank beginner. Thank you.

Amazing video dude!!
Very nice thank you!
thanks mate
I have 1999 rav 4 with 218000 miles.
It has been running cold. It’s reading Only 1/4 up the temperature gauge when I’m driving. It is getting to half way point when it is idling in place.
Heat doesn’t work that well either.
What ya think? Thermostat? Maybe something else.
Thanks
Small block chevy 350 90s van. Yeah its deep and hard to get too.
Can it also cause the temp gauge to go up and down randomly
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.
I think I should use the same coolant after changing thermostat because the fluid look orange but clean and no Gunk
Hello, I suffer from a lack of water in the car, and there is no leaking hoses or radiators, does the thermostat do that in case it is damaged, as I notice a sudden drop in the temperature of the car and it did not rise from its normal position to 80C
when Stuck Open Thermostat is to cause to lack of water , the weather is summer ??
This should be a video on signs of a bad smoke detector battery
I’m always running cold but I have really good heat coming through my Vince????
I replaced mines and it stop over heating but it never completely warms up to the middle and if it does my fans kick on. I think I might have air in the system??
You need a thermostat on that smoke detector change that battery brother LOL
What could mean when fans never turn on, temperature is normal even after replacing the sensor, and fans turning on when disconecting the sensor? Thank you!
My Mustang started leaking heavily from the cap when I parked after driving for an hour. Could that be the thermostat?
I have no overheating, hot air fans work as blows hot in the car and cold also. Temp gauges are spot on. Only thing with mine is that the hoses are different temperatures and thrown up a P0599 code thermostat circuit control high. Can't figure it out.
Probably a circuit or Valve
my temp gauge goes to the H but will cool down to half way just from sitting with it off for 3-5mins.. if i use cruise control it doesn’t overheat near as quick either.. my radiator fans aren’t working though
Hi guys need some about my car,have some issue..Oil Temp Gauge and Coolant Temp Gauge Works only when the car is Idle,but when am driving its goes down any suggestion thanks
What if my temperature gauge was reading 260 degrees the whole time but was never overheating but I replaced the coolant temperature switch and the wires and grounds are good, I just broke the thermostat housing snugging it onto my manifold, could it be from running open headers for about a week? It never once overheated on me but still always reads 260 degrees unless it’s a cold start, but I never see it in the middle of the gauge.
It’s a different season of thermostat some are higher temperature thermostat than the other one you might have for the summer you want to run a lower temperature thermostat and in the winter you want
To run a higher temperature thermostat
Summer it needs to be lower because it’s reaches the thermostat temperature faster so it keeps it cool but if your using a high temperature thermostat in the summer it’s gonna overheat
It will say the temperature on thermostat or inside the open hole just look for it
Also make sure you put some
Silicone Around thee outside of the thermostat to make sure it’s no leaks because that will cause it to overheat also
If its stuck open, wouldnt the lower hose be warm?
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
My engine temperature gauge keeps moving back and forth from H to the middle. What could that be?
How much to to change the thermostat ?
Should both hoses be hot or one cold and hot? the one going into the thermostat should be cold or warm?
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.
I have a 1999 Lexus GS 300, when I start it in the morning , it takes about 10 minutes for my rpm to go down to normal. Is that my thermostat?
People love replacing perfectly working thermostats for perfectly working thermostats.
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
I have a 2006 mazda 3s DOHC 2.3L 4 Cyl automatic ..I let my car idle 30 min car seemed up to temperature then I touched radiator and my radiator was cold to touch what good the be ?
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
I have a 2003 gmc Sierra and I’ve been doing a lot of work too it. The top radiator hose is to hot to even touch without pulling away ? Is that and or is this what normally happenes? I don’t have gauges but she’s never overheated for me yet
Lower and upper hoses are hot
I have a 2L tdi passat. My temperature gauge keeps fluctuating from 90 degrees to 85/75 degrees while im driving. I have full heat coming from my air con but for some reason the temperature just wont stay at 90 no matter how long im driving.. could this be a stuck open thermostat?
On my car the fans turn on at 190.degrees witch on gauge is normal..replaced coolant temp sensor .. someone said replace fan relay ..wats your option
What if the temperature gauge sometimes rise them goes back to normal
Does this apply to an Isuzu box truck??
I got the code but no other issues. No over heating, the heat runs fine, no leaks that I can see. Just topped off the coolant but it wasn't really that low. 🤔
I have antifreeze in front of engine. No leak found. What is issue
Hi l just noticed today that the upper hose is hot and lower hose feels warm close to cold but it's weird because lf I turn heater on it blows hot air ..this is a normal running temperature 🌡️ do you think l have a bad thermostat?....
So it's partially stuck open if my heater isn't working
My car seems hot upper radiator hose swelled up like a Ballon replaced it the thermostat is on lower hose 02 envoy but temp never goes past 200? But can feel bogging little after driving while as if we're hot ?Motor smells feels hotter then normal ?
can bad thermostats cause high fuel pressure?
If both hoses are cold...could this still be the thermostat...the gauge is sporadic...says its overheated when its not...hot air only comes once in a while and then goes back cold...overflow tank shows low but if i take the cap off...i hear the pressure release and when i put it back on the antifreeze fills back up in the overflow tank...help!!!
About how many miles does a thermostat last? My car have 70k miles, should i replace it already?
Mine was overheating and cooling when accelerating. Ended up being the thermostat
I have a 2010 Cadillac CTS it’s keeps saying engine overheating ac off
I have symptoms for the open thermostat except for lack of heat. My cel did just come on today and I got the p0128 code. 🤔
Did you get it fixed? What was it
@@Amahyze777 I replaced the thermostat and housing and that fixed it
What would/could be the cause of an LT1 over heating when parking?
The car starts overheating fast when I'm slowly manuvering (Few feet forward, few feet back etc) into a parking space
Car is fine at all other times
Water pump, thermostat, and coolant are all about 1 year old
I bled the system
Fuses and box LOOKED ok
Just put on a new ac delco rad cap
Unplugged the WP to test the fans and the drivers side works but NOT the passenger side
Neither the AC or the heat hasn't worked for over a year btw
Plugged heater core and check your cooling fans try those
Buddy! You just fixed my WRX. Holy shit
My raditator is cold and the fans blow pretty cold air but my car heats up I’ve added a auto one thermostat and it’s still heating up a mechanic told me to buy a thermostat from the dealship
I had my water pump replaced other day after my belt ripped apart. Since then I'm getting warm air and only hot air whilst I'm driving for 15mins. When I off the engine and come back 5 10min later the air is warm again. One hose is hot and other isn but takes ages. What do I do, what is the issue. Toyota carrol
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...
Same issue here, could be the thermostat, lmk how it goes with tours
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 drove on a very steep hill and my car (quite old 2003) feels a bit hot at the dashboard side. (i didn't turn on heater or air conditioning) the temperature gauge is normal. Is there any possibility where a thermostat is faulty but the temperature gauge shows normal? I didn't get any check engine light on but I did feel a noticeably hot air coming from the dashboard side and my feet.
Me too let me know if anybody gets with you
Update?
I have an e46 m43 b 19 ( closed ) all of the sudden the temp went to max , I’ll change and the water pump just in case
Need my fix for easy auto fix, when is the next 1. You got time to lean, you got time to clean!
Goodman, coming soon!
