Radiator Fan Won't Turn Off: 2014 - 2019 Silverado & Sierra: Bad Thermostat Replaced - Part 12674639

3 жыл бұрынRadiator Fan Won't Turn Off and Temperature Stuck at 160 Degrees: 2014 - 2019 Silverado & Sierra: Bad Thermostat
In the video Sean also goes over why the radiator fan won't turn off on your 2014 - 2019 Chevy Silverado or GMC Sierra. Sean informs you that the thermostat on your truck may have gone bad, and will need to be replaced before your radiator fan begins to operate like normal.
We recommend changing both the thermostat and the sensor at the same time. (GM Coolant Temp Sensor Part Number: 12608814) The three-video playlist for this job and troubleshooting is linked below:
NEW VIDEO: • Radiator Fan Won't Tur...
PLAYLIST: • Radiator Fan Won't Tur...
If you are still having issues, make sure you (safely) disconnect the battery. That will reset your trucks computer. Linked below is a trouble shooting video: 👇

I have a 2014 4WD, V6, EcoTec3, 4.3L. The fan wouldn't turn off one day but the next few days everything was fine. About a week later it started staying on again and the check engine light turned on. My temp gauge read zero when it stayed on. Only thing that popped up was thermostat when I checked for codes. Found this video and it helped so much! Fixed it and after a couple starts the check engine light went off by itself, no battery reset needed. For anyone about to do this with this model, I needed less than a gallon of 50/50 dexcool and went a little over the cold full line because the hoses were empty.

What most of these vids on this topic don't mention is that you'll need to use your code reader to reset the error code once you are done, or disconnect the battery for a few minutes. Failure to do so meant in my case at least, the problem was unchanged. Even thought there's no CEL, there is still a code.

Same problem, change the sensor, did not fix the issue. My AC stopped when the fan would not shut off. The tire pressure for 3 tires were on as low on air [ they were around 30 lbs] about a week prior to the fan not shutting off. Check engine lite came on a day later than the fan wouldn't turn off. I disconnected the battery for about 15 minutes and after putting it back on, everything worked correctly. Fan shut off correctly, tire sensors stopped showing low air, ac blew cold air and check engine lite went off. It has been about a week now and no issues [hopefully] yet.

just experienced this fan issue on my 14 sierra. my immediate thought was temp sensor or thermostat. did research and it looks to be it.. BUT in my case what i did was while driving i popped in my obd2 elm bt adapter, and literally cleared the code while i was driving with TORQUE lol and the fan stopped and guage dial corrected itself to the actual current temp. Just in case these videos dont help the issue try that, i literally stopped the fan and corrected the problem with a simple fault clear. I'm sure theres still an underlying problem which i'll do the sensor and thermostat if this happens again, but i took a lazy man approach today.

Resetting the codes will only stop this issue for a short time. It will always come back. That is because you have not fixed the root of the cause. You have to replace the temperature sensor and the thermostat, then reset the computer and the issue will be fixed. Please watch all three of our videos on this topic.

Is it possible this issue and the temp sensor can make my truck not have cool air? Sometimes the fan runs on and it takes a while until the AC kicks in real cool, other than that I drive for like 20 mins for it to hit good, It’s not broken but just delayed. I just actually fixed my AC line about a year ago so that should be good. Im curious if the truck thinks the engine is overheating with the sensor broken, and using all my cooling towards the engine and not in the truck.

Well, I Drained the excess coolant out with a spay bottle sprayer and this problem was solved!!! Of course, the mechanic denied my reservoir was not the problem. They do not teach these young kids small remedies in Tech school! Everyone know you should not over fill oil, transmission and coolant reservoir! Coolant reservoirs has a cold fill line very easy to see!!!!! SMH.

I have a 95 Trans am. My fan stays on all the time. I checked relays (all good!), changed coolant temp sensor and fans still on all the time. Do you think changing the thermostat might help ?
@TheBrothersWorkshop Жыл бұрын
I would think about looking into the temperature sensor first, and if that didn't work changing the thermostat. Not sure how it's set up, but it wouldn't hurt. Typically I like to change both out at the same time. Realize we did separate videos here, but it's something I would do at the same time.
@RozsaAmplificationLLC Жыл бұрын
Hmmm. ok, having the issue everyone else is with fan on full blast and temp gauge not moving, so going to replace both thermostat and coolant sensor and erase all codes. One question thou....picked up both parts yesterday, but online showed 2 thermostats and I picked up the 194 degree one. I see this uses 207 degree! Online shows optimal 195 to 205 and why i picked lower of the two, but also suggests 207 is factory stock and helps run better and more efficient!! Soo, which should i use and 194F or return it for the 207F unit?!??

Not much info on the best temp for thermostat. But I was wondering if a 194 would have any benefit. I noticed the local parts place has a 194 as well as the 207. Did the 207 on the wifes yukon but was thinking for my silverado be good idea to use 194

I'll be honest, we went to the parts store and gave them the make, model, engine, and year. They have us the thermostat made for my truck. There are three different motors in the 2014-19 Silverados and Sierra trucks. I would use the thermostat recommend for your trucks engine. Let us know what you choose to do and how it turns out!

Is this the same for a 6.2 on a 2016 yukon Denali? I Replaced my temp sensor and Unplugged the battery for 30 minutes everything worked for 24 hours and now it’s back to not getting any reading from from the temp gauge on the dash and the fan running constantly and turns off about 5 minutes after I shut the truck off…. Do you think it’s a Faulty sensor or thermostat issue? I only used a small amount of Teflon tape on the threads so it’s really not affecting the sensor imo.
@TheBrothersWorkshop Жыл бұрын
From our experience this seems to be a cross platform issue. This issue occurs on the 4.3 V6, the 5.3 V8 and the 6.2 V8. It doesn't seem to make a difference if the vehicle is a truck or SUV. So, if you changed the sensor and that did not fix the issue, you will need to change the thermostat. I've linked two videos for you below. The first explains the issues that you're describing. The second shows in detail how to replace the thermostat. 👇 Troubleshooting 👇 kzfaq.info/get/bejne/rcuUbMiL3bbbo4U.html Thermostat Replacement 👇 kzfaq.info/get/bejne/jdx8rKV-nayslIE.html

@@TheBrothersWorkshop - Thank you! I actually spent most of last night on the forums reading and doing some more reading and a few people suggested you need to clear any stored codes ( EVEN IF THEY DON"T SHOW A CHECK ENGINE LIGHT ) I did not have a check engine light on but when I hooked up my scan tool I did have 2 stored codes for Low Temp Sensor reading. I cleared those codes and the fan instantly turned off - one which will remain permanent until the engine completes enough cycles in normal range. I just went for a drive for about 10 miles and no fan running and the temp is reading correctly on the cluster now. Fingers crossed that was the issue if not I will definitely move on to replace the Thermostat. Thanks again!

Great video. This is what happened to me and my 2018 Tahoe. I was coming home and all of a sudden I looked down and I noticed the temperature was around 180° which is really low and I was towing a boat. So pull off the Thruway Because it was my exit to get home. Thank God, and I noticed that my fan was running super high on the radiator like really high. So I get home and get in the driveway. It’s still running crazy high. I put on one of those meter things that I have and it said the temperature in my coat was 145°. I’ll let the car cool down I take it out and everything‘s fine again temperatures back up to 210 like it usually is everything works fine. Do you think I should replace both the sensor and the thermostat?

I have a feeling that when I was driving down the Thruway for so long with that coolant sensor not working I just got a feeling that might’ve fried my seals or something like that so I’m hopeful that the damages are done on my 2018 Tahoe I’ll keep you posted. I’m gonna bring the truck in and see if I can get a leak down test done. I have somebody professional look at it. Thanks for your advice.
