Coolant temperature sensor replacement 2015-2020 Yukon, Tahoe, Suburban, Sierra Silverado GMC Chevy

If it continues it’s most likely the thermostat sticking open and actually over-cooling the engine. That also triggers the fans • Thermostat Replacement...

If your temperature gauge isn’t working, showing cold when the vehicle has been operated, the temperature sensor may have failed, which makes the fan run at max speed as a safety feature not knowing if the engine is overheating. Also, the thermostat may stick open and over cool, or closed and over heat. I replaced both for hood measure, but it was most likely the temperature sensor

I cannot thank you enough for creating and sharing such a helpful, informative video! You just saved me THOUSANDS of dollars! I am 1200 miles from home, on vacation. I have to purchase a few tools, but between your video, and my husband (a mechanic) at home, on video chat with me, I am confident that I can change my sensor out, on my own! Thank you, from the bottom of my heart! As a female, the dealership tried to tell me that a whole bunch of things need to be replaced and that it will cost me and arm and a leg! My husband throughly checked& tuned up our truck before I left for vacation, so we know the dealership is lying! My Yukon Denali is doing EXACTLY, EXACTLY what your wife’s truck did. I am forever grateful for your help! Bless you Sir! 🥰

[@dannyjohnsonsgarage]

When you get it home, the thermostat can also stick open and show cold as it over cools the engine. If you continue to have trouble, the thermostat would be the next thing to look at.

I took my 2015 Chevy SUV LTZ to dealership to have the same sensor replace- they where charging me $203 to take the fluids & clean, then labor then part a $450job, all they need to do is just drain the fluids down- so after watching your video, we did not get it done there-Thanks for your knowledge to inform people like us

[@nordicpride9708]

Yeah but how many miles are on your truck? Sometimes they do things based on service intervals. Dex-cool doesn’t last forever and needs to be changed at specified intervals.

Excellent video, thanks. 2016 GMC yukon XL 4 X 4 WITH 5.3. Mileage = 125,000. 1st time this has happened. I purchased the new coolant temperature sensor at Auto Zone for $17.00 and a gallon of the antifreeze concentrate for $21.00, I applied the tape, and took about 90 minutes to set up, do the job, put everything up and clean up. Working great. Total spent $38.00.

Wanted to leave a comment to say thank you! Seems like my 2015 Yukon XL has been riddled with common issues & it's just one thing after another. KZbin has become my go-to place for solutions. I came across several videos for this issue, but none as easy to follow & quick to the point as yours. I'm trying to learn to fix the smaller details myself. I took this as a learning opportunity & got my hands dirty with my dad. Not only did we get the issue resolved, but it was nice to bond over his intrest too. So thanks again!

Temp gage showed 160 degrees or lowest posible readng, whcih is typicalls 186 F. and both fans were in overdrive. and ran for about 20 minutes after arriving home. Bought a new cooling sensor today for $18, had extra antifreeze. Your well produced how to video turned this repair into an hour event even considering the trip to auto parts store.

[@troytremaine5819]

This video is absolutely perfect, thanks for sharing. My 2016 Yukon did the same and I received a quote from the dealership and they wanted 1300.00 to diagnose and repair. (THEY ARE CRAZY). I did purchase the GM Brand sensor for 53.00 and replaced it in merely 10 minutes. I don't know why you had to remove the entire intake silencer or drain off the radiator hose. I removed the intake connection and left it connected to the air filter section, removed the sensor with towels around it to keep fluid from going over the entire engine/ground; and I only lost about 3 tablespoons of fluid and put the new sensor on. Reconnected everything and now runs perfectly. THANK YOU FOR THIS AMAZING VIDEO.

[@dannyjohnsonsgarage]

I also replaced the thermostat, but made the videos separate as well for those only doing one repair. It doesn’t hurt to drain a little fluid for less of a mess. I’m glad you enjoyed it

[@76Ronix]

Thank you so much for posting this!! I have a GMC seirra that had this exact problem. If i were to take it in to a shop, no doubt I'd be charged $1000s. I fixed it myself yesterday with your guidance 🙏 it took me a lot longer than it took you😂 but it's fixed. I literally can't thank u enough. The AC quit working around the same time and now it's totally back to normal. No check engine light. Happy day!!

[@mississippioutlaw2285]

​@dannyjohnsonsgarage will the radiator cause the fan to come and do you think it may be clogged up because I don't see no sign of coolant on the ground

[@dannyjohnsonsgarage]

@@mississippioutlaw2285 the fans will continue to run because the vehicle has noticed. It is more hot than usual, just like how they will also run if it thinks it’s too cold than usual. I would try to burp the system as you saw at the end of the video by pouring coolant directly into the radiator hose that goes into the radiator, you don’t want to only have coolant in the gas tank, but in both. Make sure that the engine is cool when you’re doing this, so it doesn’t spray coolant and burn you.

[@alirizvi3235]

I had the same issue. I changed the temperature sensor and it worked like a charm! - 2015 Suburban - 265,xxx miles - CEL was on: P0118, P0128 - The fans would stay on with the car on and off. - A/C was not turning on I started searching away and saw your video! Everything was spot on! Working just fine! Big thank you!!

[@dannyjohnsonsgarage]

If it comes back it may be the thermostat sticking as well. Just fyi kzbin.info/www/bejne/l3bJmJ6ujMl1j9ksi=3nzNZIdNLFsqB4Ze

[@rwwade]

Thanks for this video. I bought the part a while back after watching how to replace it on an Escalade, but then I realized that my Tahoe had the air silencer (which the Escalade did not). I was not sure how to proceed with the air silencer, but your video was very clear and helped a lot. I did not do the optional part of removing the hose -- when I removed the old sensor I was prepared with some paper towels. Things to note for others dealing with this: 1) if your check engine light remains on after replacing the sensor you typically have to start/stop the car 3 times before the car recognizes that the previous problem causing the light to illuminate no longer exists. 2) if your situation is like mine, when the sensor is bad the fan will stay on for 5 minutes after the car is turned off. For a long time this was just annoying, until it happened so often that it drained my battery and my Tahoe wouldn't start. I saw someone ask if this must get fixed - I don't know about if it is bad for your engine to let the can continue running all the time, but it definitely drains your battery.

[@rwwade]

After 5 days the problem came back. Going to replace the thermostat next: kzbin.info/www/bejne/l3bJmJ6ujMl1j9k

[@stpx]

I have the same issue. Replaced the coolant temp sensor, worked great, then about a week later it started up again. Did replacing the thermostat work?

[@rwwade]

@@stpx yes. It was very easy except I didn’t do a great job collecting coolant that spilled. I hosed my driveway off and it didn’t leave any marks. Make sure you replace coolant with correct type. Also try and fill the hose up before you reconnect it so you don’t have too much air in the system. I assume it matters.

[@ansgr0903]

Thank you for the help! I didn’t have a 19 mm deep socket and figured what the heck I’ll buy one so in total with new sensor, socket, and coolant it totaled less than $50 to do myself. Thank you again!

Good to hear. If it continues to happen, it’s also common for the thermostat to stick open and overcool the engine and run the fans kzbin.info/www/bejne/l3bJmJ6ujMl1j9ksi=Swj6E2HklqMBS4ru

[@damarine2008]

Are you talking about the Water Pump Outlet Assembly with Thermostat? I have the same issue. Not sure which one's the problem. My fan kept blowing even with the truck off to the point where it drained my battery.

[@acebillz22]

Saved me, one guy told me he got me on the price, did it, and then charged 450! I just did it for 30$ with help from a friend who’s a little more car savvy than me and i can definitely do it myself from now on. Best video for this ever!

Great job. If the fan continues to run with the new sensor, the thermostat can also stick and cause it to run. It’s also not too hard. Just fyi kzbin.info/www/bejne/l3bJmJ6ujMl1j9ksi=-NY_JOea38jVlPC5

I also did the thermostat, which can cause the same problem with the fans, so if they happens here is a video kzbin.info/www/bejne/l3bJmJ6ujMl1j9ksi=kHxSVZ7ZmOijwQ5F

[@johnw763]

This was helpful in diagnosing my 2018. Only difference in steps I followed… 1. only remove the right side of the air intake, use a bungee cord to suspend in the air to the left. 2. Place rags around the sensor when removing to minimize spill. 3. Clamp the large hose going into thermostat housing. Little to no spill, completed in 20 minutes, no more high fan and temperature on dash properly reading now. 👍

Awesome video. This happened today to my wife’s Yukon denali and I swapped out the coolant temp sensor following your instructions and she’s back in business. Thanks!

[@shanegidley]

Excellent video! Just a little PSA here. Replace your thermostat also! The same guy here has a similar video for replacing a thermostat, which is right next to the temp sensor. It's a part that is likely to eventually fail so replace it! Expand his description of this video, he says the same thing, I think I just never saw it. Also you find the handy links to order the parts there. I found this video and carried out the steps as I thought it would solve my trouble code which seemed to point to the temp sensor. For some reason, I was too dense to heed the fact that in his video, his sensor was reading zero while mine seemed to read ok. I let myself be confused by the trouble code. It was P0128 "engine coolant temperature is below the thermostat regulating temperature". I thought maybe my temp sensor was intermittently failing or off. Nah. A new thermostat is what fixed that. The temp sensor was fine. The good news I have excellent hindsight so it's all perfectly clear now what I should have done!

2016 Suburban LT... You just saved me sooo much money, brother! It really was simple! It's amazing how that little sensor can effect the operation of the whole engine.

Thanks for posting another vid of your Denali.

[@georgerazzer]

Great channel. I subscribed! Had this issue today and these videos explained everything really well. Only recommendation is to edit the comments to ensure people reset the cpu by pulling the negative cable on the battery. Also, for anyone else out there, when removing the small hose from the thermostat housing to get that clamp out of the way, be careful. When removing it the piece my hose was lcamped to may have been on the verge of dry rot, or i didnt have the clamp opened all the way and the nozzle broke off in the house so i had to get a new thermostat housing and install. Oh well, probably good i changed the thermostat anyway :) BTW Danny has a video for that as well :)

[@dannyjohnsonsgarage]

Yeah, disconnecting the negative battery cable is covered as the first step in the video, but people comment telling me they didn’t do it as shown and short it out. It’s always a good idea to disconnect the battery when working on anything with an electrical connector but having people follow the instructions is another thing lol

If it continues, please see my thermostat video. I did both at the same time but others have also said the thermostat needed replacement shortly after kzbin.info/www/bejne/l3bJmJ6ujMl1j9ksi=vnRKovHPymfl2xhb

[@kevinrayo7439]

God bless you !!!!

[@dannyjohnsonsgarage]

If it continues, the thermostat can also stick open and cause the fans to run. Just a future FYI kzbin.info/www/bejne/l3bJmJ6ujMl1j9ksi=GJZWoL0xarY8Qk65

Thanks for the video! You just saved me couple hundred $$$

[@dannyjohnsonsgarage]

If it continues to happen, the thermostat can also be the culprit kzbin.info/www/bejne/l3bJmJ6ujMl1j9ksi=kHxSVZ7ZmOijwQ5F

👏👏 Absolutely fantastic. Very well done. Extremely helpful. Ty 🙏

I have a 2016 Sierra 1500 and my temp gauge doesn’t move and my fans are running on high, like in the video. I replaced the thermostat and still same issue. im going to replace the temp sensor and hopefully that fixes it. Oddly enough, I don’t have an error code show up on my dashboard.

[@dannyjohnsonsgarage]

I’m betting the temp sensor will fix it

[@humbertocantu1986]

My Tahoe was doing it for a good while and I ended up changing the censor and the thermostat then we reset the code and it hasn’t done it since.

[@xourheartsdesire]

I replaced this months ago. Your video saved me $$$. The truck is doing it again. Whats the deal? Does anyone know how this could go bad in months time?

[@dannyjohnsonsgarage]

The thermostat can also have the same symptoms. It sticks open and over-cools the engine and it also causes the fan to run kzbin.info/www/bejne/l3bJmJ6ujMl1j9ksi=XUarh9bNgi3pjxTE

[@sergioborjon2466]

Thanks for the video it was very well explained, you help me a lot .

[@schmidhappens]

Super helpful!

[@dannyjohnsonsgarage]

Keep an eye on the thermostat. It can also do the same thing with the fans as it over-cools the engine kzbin.info/www/bejne/l3bJmJ6ujMl1j9ksi=vJSxJXHqlTJ1OjZ6

[@bobcook8576]

P0128. Your thermostat is stuck open. Coolant sensors only break if you smash them with a hammer. Buy a new thermostat and disconnect your battery for 10 minutes. Most thermostats wear out at the 150k mileage level. Change your Coolant its overdue.

[@dannyjohnsonsgarage]

This video is taken from the thermostat replacement video

[@hkhunter1]

Great details and well done

[@Rescuemissioncpr_indy]

Replaced my thermostat sensor but that didn’t fix it, i then replaced the thermostat and that did the trick.

[@AlexV-pf3io]

Did you have same symptoms: Zero on gauge, fans continued to run after the engine off?

[@kyleclonts6238]

Video was perfect. We did exactly this and it fixed it. However 7 days later it happened again. Could this be a bad sensor or would there be another reason it might fail after being fixed?

[@dannyjohnsonsgarage]

I would next verify if the thermostat is in fact bad and sticking open. It might be over-cooling the engine. kzbin.info/www/bejne/l3bJmJ6ujMl1j9k

[@dennisbond9148]

Thx for the very good video 👍very helpful

[@varrido1321]

Thank you for the video job done very helpful

[@ievgeniiprylipko]

Great video hope it’s work on my car, thanks

[@dannyjohnsonsgarage]

I also did a thermostat, so check it out as well if it still over-cools kzbin.info/www/bejne/bZ6td2iChpiihtU

[@christophercmosley]

I’m going to try to tackle this tomorrow myself. The only thing I’m scared about is the burping the system part with adding the coolant back.

[@dannyjohnsonsgarage]

You should be fine if you follow the video. I also have this version that has the thermostat. It can also be bad in most cases. Be sure to unplug the black negative battery terminal when you start as the video shows, and make sure it has cooled down kzbin.info/www/bejne/bZ6td2iChpiihtUsi=jGqPObhAQsJGFpRv

[@christophercmosley]

@@dannyjohnsonsgarage thank you! 🙏🏽

[@bjpatpat5801]

thanks will try to do this hope that it works out this (is) the info that I needed

[@dannyjohnsonsgarage]

I also have a video covering the thermostat. It can also cause the fan to run and read cool if the temp is actually cold from the thermostat sticking open kzbin.info/www/bejne/bZ6td2iChpiihtUsi=4yaC93Wzh5APF8zF

[@bjpatpat5801]

after replacing the sensor 3 times, I took it to a friend and he replaced it as well as the wiring that plugs in it and it seems to work. I will ride to see if that was the problem

[@robertingram2009]

That's that was a very good video thank you.

[@mr.knight7816]

Hi quick question does your Yukon run at 210 all the time? I changed my thermostat and temperature sensor and it stays at 210 now.

[@dannyjohnsonsgarage]

Yep. 210 all day

[@mr.knight7816]

Danny thanks for replying. Good to know I taught something was wrong with it. Lol

[@brittanyjohnson-mills9451]

Hello, thank you so much for this video. I have actually replaced this twice within the last six months on my 2015 Tahoe. The problem seems to keep coming back however :( first we thought it was a faulty part and replaced it again but now the fan is running again and the car is not overheating. What do you think this could be?

[@dannyjohnsonsgarage]

It’s not overheating, but is it over-cooling? If not at 210 degrees when warm the thermostat may be stuck open kzbin.info/www/bejne/l3bJmJ6ujMl1j9k

[@davidburdyck7308]

This video helped tremendously for the repair and once we ran the vehicle; the temperature gauge worked great. Now however, every now and then; the sensor will trip and the gauge won’t work again. Ofcourse the fans will come on again, but each time I disconnect the battery terminal it rights the system again for a few days or more before happening again. Any idea? Only thing I can see different is we used an OEM replacement and not the part from the dealer, but I’m not convinced that is the issue.

[@dannyjohnsonsgarage]

It’s possible the new sensor is also faulty or the wires or plug on the vehicle side have a short and once it loses communication it faults out

[@rza380.]

All Hail the 10mm socket😂😂😂😂

[@user-qm5nz5xo6e]

👏 Very helpful Thank you

[@JohnButtino]

Great video what are the symptoms of needing to replace my engine is at 200 degrees while on a long trip .

[@dannyjohnsonsgarage]

210 is perfect. Symptoms would be the fan staying on and reading zero when hot (looks like 160 degrees since that’s where the gauge starts).

[@JohnButtino]

@@dannyjohnsonsgarage thanks I’m having problems with the good ole P0420
