I'd like to nominate this channel for a Daytime Emmy for "Outstanding Vehicle Repair Program." This was quite possibly the most concise, BS-free, helpful repair video I've ever seen. My 2019 Yukon thanks you.
Thank you for the kind words! Here is a playlist with many more videos like it on the Yukon. ruclips.net/p/PLIjr-uSYDZi7J7EQ1ErTn1Yzi6ET_3Ssr&si=FsSLYQ2DaH67DMR4
Being the owner of a 2016 Tahoe that just clicked over 100k miles I have a feeling this is my new favorite RUclips channel 😂. Your videos are incredibly detailed and thorough.
I’m glad you found it. You may have seen the playlist, but if not here it is Yukon / Tahoe / Suburban / Escalade Owner’s manual Bells & whistles ruclips.net/p/PLIjr-uSYDZi7J7EQ1ErTn1Yzi6ET_3Ssr
Perfectly described procedure in the video. No wasted moves, no verbose video "ego" nonsense, just straight up good info. Fixed GF's 2016 GMC in 20 minutes. Changed sensor first- issue remained, so a month later did the thermostat, and that fixed it. As Danny suggested, probably best to do both at once. Thanks Danny.
@@captinhoop The fan stayed on our Tahoe when the truck was turned off and the coolant temperature gauge bottomed out at 160. Danny had a video of the same thing happening to this vehicle in the video. I changed the engine coolant sensor. Fan problem went away but the vehicle coolant temp has trouble getting warm past 180 degrees and if it reaches 210 it doesn’t stay there. I am going to replace the thermostat this week . I think the same happened to Danny because there is footage in this video that was in his coolant temperature sensor replacement video. If you plan to do it yourself I would do both the sensor and thermostat ar the same time, will safe you time and money on coolant. If one goes out I think the other is either also bad or not far behind.
Just wanted to say thank you for the spot on step-by-step instructions. Your video helped me replace my stuck thermostat and saved me a pile of money and time from going to the dealership. Thank you!!!
Hey man, thanks for the video! Just changed out my thermostat on my 2017 Yukon. And it was a snap. I really like the idea of taking off the radiator hose to catch up the antifreeze.
Your video saved me $1,100!!!! My local dealership quoted me 1200 for my 2016 Denali. Bought the thermostat and some coolant....$81 bucks and thirty minutes. Thanks!!!
I did your procedure step by step as well worked 🙏.I was also told by the dealership that it would be 1200$,And this is after I had it serviced by them one time,had 0 issues 0 check engine lights,had very extensive and service record by previous owner (by different dealerships) well maintained beautiful 18 Suburban,I only needed a oil change that was due by oil life dash ,but was talked into 1600$ of “preventative maintenance “ love my vehicle and lacked mechanic knowledge at that time,Have had to take it back to them about five times since that “maintenance “ was done,from 3evap leaks to repair of my rims that they damaged and a/c loud noise after they replaced filter,also my battery was stolen and replaced with a AAA Battery that they are blaming AAA for because it was towed to dealership by them. So when this code came on they claimed that they didn’t touch that area and quoted me 1200$ masked my rage walked off and saw your video shocked at how cheap the part sensor cost so I bought the housing as well for “preventative maintenance “😂as well worked like a charm .thank you 🙏
I did this today. Thank you very much for this video without your instructions I would not have a been able to do this myself. I really appreciate the time you took to put this video together. Just a small note that I did not drain out as much coolant as you did. I just let it drip all over the floor and then I refilled it after I was done.
I always jack the vehicles up in the front and run them with the reservoir cap off or radiator cap if there is one. Once the thermostat cycles any trapped air in the system will come out.
Lol just reading a lot of the comments.. there right BROVO I just did the hole job seams to be ok I tried just the sensor first but the problem came back so I the thermostat and did the full job 🤞🤞this the wife’s truck for the 3 kids need this baby to stay on the road thanks Danny.
Awesome Video, very detailed, and easy to follow. Saved me alot of $$$. Took me about 30Min to complete the thermostat replacement on my 15 Yukon XL 5.3. Only thing was I had to install an aftermarket because all OEM are in backorder for some reason.
I think I have to do this to my 2018 Tahoe and the way you explained it was flawless and I'm taking it that it was a 30-minute job cuz the video was only 10 minutes but appreciate your video great job
I just replace my stat, followed everything to the T and almost all of my coolant drained, never really leveling out. Not sure what I did wrong but all together now with new coolant. Good to go, thanks
A good mechanic should charge you 1 hr labor and parts (they will mark the part up). A shop near me charges $120/hr but I think I will just do my own. Dealerships rip people off and some shops do it as well.
My suburban temperature gauge sometimes don’t read the temperature I did replace the temperature sensor still haven’t the same problem I should change the thermostat too
@ in the video I have the negative battery cable off for the repair to reduce the risk of elective complications, as well as to reset the system. If you skipped that step, remove the negative battery cable for 10 minutes and reinstall
So, I changed the temperature sensor and the thermostat on my 2015 suburban, but my gauge is still reading 160 and the fan stays on after I turned the engine off. Does it only reset if I unplugged the battery terminal? Okay. So I disconnected the negative terminal on the battery. Then, after a few minutes, reconnected it and everything worked great! I checked for leaks and had to top off the coolant, just a little. Thank you for this great video!
No prob. In the future you’ll also want to disconnect the negative battery terminal when working on anything electrical so it never shorts anything out. 👍🏼
Excellent instructional video. I replaced both the sensor and the thermostat. It ran fine for about a week after the sensor. Just changed out the thermostat. The fan is still running. Do you have any suggestions?
@@JakeMiller-wc6yhhad the same issue especially during the winter…16 suburban 5.3L while driving the temp gauge goes down to 0 or (160) then when I disconnect the battery for a few mins then put it back on the gauge goes back up to its current temperature….happens frequently during the winter idk what it could be…haven’t tried replacing the thermostat tho

Good day, when replacing temp sensor or thermostat will the engine lite go off.thanks for your time. I read the comments removal of negative battery cable will reset the lite correct?
Would this help fix with the fan staying on after the car is shut off? Even though its not over heating? I replaced the thermostat sensor, but it still seems to think the car is hot. The gauge is reading 160 and the check engine light is on. Its giving me a P128 reading on my diagnostics reader. I am wondering if this needs to be replaced as well. Great video! Thanks!
Yes, that code indicates the car is running too cool, so most likely a bad thermostat that has stuck open and lets too much coolant flow and overcool the engine
Danny, what would cause a small leak if coolant under the drive side air dam? I replaced the thermostat a month ago. This can't be left over from what spilled.
My fan cuts on and off from time to time and I replaced the sensor but it still comes on. Could this also be the thermostat I have to change? Because a shop told me I should replace the fan but I’m not sure they are correct about that.
Yeah, the thermostat sticks open and over-cools the engine. The fan comes on because it recognizes the engine should be hot and it’s reading cold. It’s most likely the thermostat
If the thermostat is stuck open it over-cools the engine. It’s running under 160 degrees and the computer knows the temperature should be higher since the transmission and other temps are high. Now, if the sensor is in fact bad, it could be that too, but many times it’s the thermostat
Yes it says it will. www.amazon.com/ACDelco-15-11125-Original-Equipment-Thermostat/dp/B01K8BJ7BS?crid=1W7TOBWO5Q5WB&keywords=thermostat+gm+12674639&qid=1666942682&qu=eyJxc2MiOiIwLjk1IiwicXNhIjoiMC4wMCIsInFzcCI6IjAuMDAifQ%3D%3D&sprefix=thermostat+gm+12674639,aps,150&sr=8-2&linkCode=sl1&tag=2004047-20&linkId=f878d8b5f4eda040f9cd11c6ef508f0f&language=en_US&ref_=as_li_ss_tl
Did the thermostat you order come with any other gaskets to put under the thermostat? I replaced mine, it came with a gasket that I left inside the thermostat just like how yours came. But mine still leaks from the bottom of the thermostat. I made sure it was on there snug but it still leaking very slowly from the bottom of it. Not sure if this has happened to anyone else.
I wonder if it cracked the aluminum housing.if you find that’s the case, here is the replacement that comes with a thermostat ruclips.net/video/47mCuP9KJro/видео.htmlsi=Vw4roi9jOKrp5lpm
I followed your video of replacing the coolant sensor and this one about the thermostat sensor. The engine light went off. But while riding the engine temp gauge never moved from 0 and the fan won’t turn off after the truck is off. What else can I do?
Did you disconnect the black battery cable to reset the system? It should have been unplugged during the repair. If you did, it could be a problem with the wiring or connector for the temperature sensor. You might be able to do a continuity test ruclips.net/video/-BUzm-OeGhE/видео.htmlsi=8yEWClriLsmf-BUy
@dannyjohnsonsgarage yes it was disconnected during the repairs. And our next thought was a bad fuse but I don’t know which one according to our manual. I have a 2019 GMC Yukon Denali 2WD.
Awesome video. Thanks so much I just added a 2018 tahoe lt to my garage and I look forward to utilizing more of your DIY videos in the future. I’ve already sub’d and click the 🔔 that’s how I was notified of this video. I have a engine light on but I can’t remember the code because it’s been in the body shop for several weeks now hopefully you could help me once it’s returned to me. Again thanks for the awesome videos
Hey Danny, you say to make sure to fill all 3 areas back with antifreeze but there’s only the hose and the Degasser tank. Are you counting the degasser as 2 because it says front and rear?
@@dannyjohnsonsgarage well I just poured it into the hose while it was hooked into the thermostat as full as I could, hooked it back up. Filled up the degasser and everything worked perfectly. It actually fixed my problem. Fan stopped running and having noticed anything weird. Appreciate the response
@@ryanbuckner2405 it should work air pockets out, but when people fill only the degas bottle and nothing is in the radiator is when it usually causes trouble, so I recommend burping as listed above. Glad you got it going 👍🏼
I changed the thermostat and its still doing the same thing, the code it was giving was for the thermostat thats why i changed it. i cant even run the AC because it blows hot and i don’t want the suv to overheat. Do you have any suggestions on what could be the problem?
Did you disconnect the black battery cable to reset the system? I would next look into the temperature sensor ruclips.net/video/4wd0n9F6--Q/видео.htmlsi=9KGatLtFV0SA1qlg
Thank you for the video. I used it as recently changed the temperature sensor and then at a later date changed the thermostat on my 2015 suburban. However, after the thermostat change the temperature goes high to 210 and above when before it would stay at 180-195. Is there anything that I should be looking at or that I might have done wrong? Thank you in advance for your help.
@ I didn’t unhook the negative cable and the fans are still staying on. I guess it could be the thermostat sticking open but why would the fans stay on like it’s hot when it’s very cold?
@@captinhoop If you don’t disconnect the battery it may not reset. You’ll know if it’s corrected if the temp gauge isn’t at zero (showing less than 160). If the thermostat sticks open it causes it to run the fans and show under 160 degrees as well
@@dannyjohnsonsgarage copy. Well my wife is picking up a thermostat but I guess I’ll try a hard reset and see if that fixes it before taking out the thermostat. Should only take 10-15 minutes.
You most likely won’t smell it from the thermostat, so the heater core or even a leak in the engine can make it smell through the intake vents for the air conditioning
@@dannyjohnsonsgarage Thanks for your input, I'm sure the thermostat is pooched anyway, it had the same symptoms as in your video. The dash disassembly for the core is too much for my ADHD lol, to the shop it's going!
Any clue on what could cause the engine light to stay on? I’ve replaced the water temp sensor and thermostat but the temperature won’t go up. The cables on the water temp sensor didn’t looked damaged or anything but we did drive through heavy rain recently if that can play a factor?
I have seen my temp pegged at 210 straight up so I think that’s normal. It may be better to run colder but you also need to verify how the rest of the vehicle is designed. It may try to heat the engine up by leaning it out or give you a fault code, so I wouldn’t recommend it without a tune
I have a 2015 yukon ive replaced the sensor with an oem unit twice. Still ends up getting stuck bottomed out like a simple electrical issue. If i clear the codes the code goes away and the temp gauge starts reading so its not the thermostat. Any other ideas?
My radiator fan was staying on after I turned off my Tahoe, so I replaced the temp coolant sensor and it worked for a few days but the fan started staying on again.. would anyone know if I should change the thermostat or could it be a relay or a fuse?? Thanks in advance..
From what I can tell this is a 194° thermostat. For Danny or anyone else that’s used this one did you notice a drop in fuel economy. What I’m reading online it’s better to stick with the 207° thermostat like oem
This is a GM OEM thermostat and the engine temp stays at 210 as it’s designed. If it runs cooler the fans may kick on again and run continuously thinking something is wrong

Yeah, the thermostat sticks open and over-cools the engine. The fan comes on because it recognizes the engine should be hot and it’s reading cold. It’s most likely the thermostat
Can I ask why does replacing the thermostat fix it and not replacing the sensor?
If the thermostat is stuck open it over-cools the engine. It’s running under 160 degrees and the computer knows the temperature should be higher since the transmission and other temps are high. Now, if the sensor is in fact bad, it could be that too, but many times it’s the thermostat
do you have set the check engine light

Hey Danny, you say to make sure to fill all 3 areas back with antifreeze but there’s only the hose and the Degasser tank. Are you counting the degasser as 2 because it says front and rear?

However, after the thermostat change the temperature goes high to 210 and above when before it would stay at 180-195. Is there anything that I should be looking at or that I might have done wrong? Thank you in advance for your help.
Likely the old thermostat was opening early. Your engine should operate around the 210 mark.
Do you have to reset the computer by taking off the negative wire after the coolant temp sensor is replaced?
I show removing the negative cable in the beginning as it will reset the system and also be disconnected during the repair to reduce a short.
@ I didn’t unhook the negative cable and the fans are still staying on. I guess it could be the thermostat sticking open but why would the fans stay on like it’s hot when it’s very cold?
@@dannyjohnsonsgarage btw I’m a new sub lol
@@captinhoop If you don’t disconnect the battery it may not reset. You’ll know if it’s corrected if the temp gauge isn’t at zero (showing less than 160). If the thermostat sticks open it causes it to run the fans and show under 160 degrees as well
@@dannyjohnsonsgarage copy. Well my wife is picking up a thermostat but I guess I’ll try a hard reset and see if that fixes it before taking out the thermostat. Should only take 10-15 minutes.
Could a bad thermostat cause a coolant smell from the vents? Or is that specifically a leaking heater core?
You most likely won’t smell it from the thermostat, so the heater core or even a leak in the engine can make it smell through the intake vents for the air conditioning

Thanks for your input, I'm sure the thermostat is pooched anyway, it had the same symptoms as in your video. The dash disassembly for the core is too much for my ADHD lol, to the shop it's going!
Any clue on what could cause the engine light to stay on?
I’ve replaced the water temp sensor and thermostat but the temperature won’t go up. The cables on the water temp sensor didn’t looked damaged or anything but we did drive through heavy rain recently if that can play a factor?
Did you reset the system by having the negative cable off for the repair?
@@dannyjohnsonsgarage yes twice
My temp gauge is at 210 and then spikes its way to 260 then if you let out of gas it starts to fall back to 210 isn’t that the thermostat sticking?
It could be sticking closed. Or you could have air in the system and want to burp it like in the end
My Gmc yukon's fan are staying on. I saw your temperature sensor video. Do I need to change both as well?
I would try the sensor only first before buying the thermostat and housing.
Spin clamp on top rad. hose has no give for plastic could crack rad.
Factory clamps compensate for that
Are there any benefits to runing a cooler tstat like a 180deg one, i have stage 2 btr cam ,headers,catback on 18 tahoe ? Stock is 202 i believe?
I have seen my temp pegged at 210 straight up so I think that’s normal. It may be better to run colder but you also need to verify how the rest of the vehicle is designed. It may try to heat the engine up by leaning it out or give you a fault code, so I wouldn’t recommend it without a tune
I have a 2015 yukon ive replaced the sensor with an oem unit twice. Still ends up getting stuck bottomed out like a simple electrical issue. If i clear the codes the code goes away and the temp gauge starts reading so its not the thermostat. Any other ideas?
I can only imagine it’s the electrical connector maybe at the plug

My radiator fan was staying on after I turned off my Tahoe, so I replaced the temp coolant sensor and it worked for a few days but the fan started staying on again.. would anyone know if I should change the thermostat or could it be a relay or a fuse?? Thanks in advance..
If the gauge is reading zero when warm, it’s most likely the thermostat is bad and is over-cooling the engine.
From what I can tell this is a 194° thermostat. For Danny or anyone else that’s used this one did you notice a drop in fuel economy. What I’m reading online it’s better to stick with the 207° thermostat like oem
This is a GM OEM thermostat and the engine temp stays at 210 as it’s designed. If it runs cooler the fans may kick on again and run continuously thinking something is wrong
Okay perfect thanks man!
did this today and now my radiator fans wont turn on :{
They arnt supposed to always be running
I over tightened mine. Entire engine blew up and I parted my 2018 out at the junk yard. Nobody got time for this
What!?
Easy peezzzey lemon squeezy
my engine does not look anything like the engine you have in the thermostat video
