I literally took my car to a shop to get an estimate to replace the thermostat housing and I was quoted $881!!! The man said bc it’s a three hour labor job. Definitely not paying no mechanic to do this thanks to your video.
For anyone stuck trying to get that out of sight bolt off for the pipe that goes to the thermostat - remove the ecm board mount and battery bracket Makes it way easier
Thanks for the video. This is a super simple fix for the dreaded "steering assist disabled" and Temp Sensor reading zero issue. At first i only replaced the temp sending unit, but that was not the issue. The thermostat was indeed the issue for my 2020 Blazer. Just replace both while you're in there. The 10MM holding the tube in place is indeed hidden and the trickiest part. Just use a 1/4 inch swivel ratchet with a short extension to get at it... Thermostat unit, gaskets, O-Rings, $28.99 on Amazon. Sending unit 15 bucks. (I did not replace the included tube. No need)
Currently about to do this soon on my 2020 acadia already have all the parts. Steering wheel assist, ac blows warm, Temp gauge flatlines, fan blows on high nonstop. I reset code and it went away for a day. Reset it again and it’s been a week with no issues, but this is a temp fix. It’s crazy how a vehicle with 38k miles can have these issues and all these motors have the same exact problem. GM messed up big on this.
I’ve read that people have replaced the thermostat and temp sensor and it comes back. I read on a forum it’s related to the wiring going to the thermostat, I think that it wasn’t sleeved and gets too hot.
@@aelius_audio I took time out & replaced thermostat, temp sensor & spark plugs yesterday. Everything running smooth sofar. Temps all in range. 👍🏽 I did hear something about the wiring connector to the temp sensor from a person on the acadia forum. We will see what happens if all fails atleast i got new parts 😂 will post back if I have anymore issues.
@@trydecaddyz6831 Is there a model year in which they fixed the design flaw? I'm torn between choosing a 2022-2023 Cadillac XT5 with the 3.6 or a 2020-2022 Lexus RX350 with the 3.5 2GR. Neither are perfect in reliability but what would you say is the better one? I'm also concerned with the 3.6 having Active Fuel Management like the GM V8s and issues like excessive oil consumption
So I’m having the issue with the coolant temp reading as it was stuck on cold and threw the driver assist reduced warning , thought it was a stuck open thermostat but as I was driving to the parts store it started reading the coolant temp as usual. Could that be just the sensor and not the thermostat. If it’s just the sensor do I still have to take the thermostat out to get to it ?
@trydecaddyz6831 did that fix there issue? I have a 2019 chevy blazer same exact problem with mine steering assist disabled temperature is all the way on cold fan runs constantly no ac then check engine light comes on then all of it goes away. My car is not running warm at all no missing antifreeze no leaks
My 2020 Chevy Blazer had the exact same problem! I just got quoted from the Chevy dealership to replace the thermostat. Around $1700 total. 250 for the inspection to tell me that was the issue, 250 for the parts, and 1200 for the labor. That seems really high, is it?? I originally took it to a Firestone and a Wheel works and they both didn’t have the equipment to inspect the AC system so I went to the dealership. Thanks for the video btw, super helpful to see.
I'm sorry for what I'm going to say but. You are just explaining the easy part of it. You are not explaining the hardest part, you're not explaining the how do you take out the bolt down on the back, the one that tie down the hose that hold the fucken thermostat. And you don't also explain how to disconnect all the small aluminum hoses stick to the engine above the thermostat. Also you forgot to tell that you can brake the thermostat in 2 pieces inside the engine block too. If you are going to make a video explaining people how to do something, do it right all with all the steps no just the easy parts.
Omfg I have running around my steering went out going 60 on the highway I am so lucky it was me and not her she would of panic. I asked so many people found the issue by my neighbor who own Chevy he said buddy welcome to Chevy the issue is this in one min he said I dealt with all my Silverado’s he was a life saver going to trade the vehicle after it’s fix hate Chevy
The hard part was removing all the crap on top. With the correct size sockets, if you have some mechanical knowledge, you should be able to do this. Draining the coolant shouldn't be a problem. Just take your time and if you need to take pictures as you're taking stuff off. Totally blown away by what some are saying the cost at a dealer to replace a simple thermostat. BTW, thanks GM for making parts that don't last 5 years.
@@dlcnws4418 they quoted my neighbor 1100 at two different locations. I said you get the parts I'll do it for dinner and beer. it's really not a hard job. flat head screwdriver a couple 10 mm bolts and some 13 mm bolts i use a small makeup mirror for the side bolt. some 50/50 coolant and the part. I drained out the coolant all the way so i didn't make a huge mess.
Could you please share the part number to make sure that i'm purchasing the right thermostat?
Did you ever get the part I am trying to find it when I look it up it gives me a small sensor

@ good to hear thx, hope it lasts for ya
@@aelius_audio Hellyea, appreciate it. I only did spark plugs because the manifold had to come off anyway so I thought might as well.
Why would a 2020 model year car already need a thermostat? They should last wayyyyy longer than that
@@RyanEmeryLovesCars design flaw
@@trydecaddyz6831 What makes it a design flaw?
@ something about its position between the heads and under fuel rails

What new gaskets will I need? Does the o ring come with the thermostat?
@@rosasr12345 intake gaskets and the red pipe seal that goes into thermostat it doesn’t come with thermostat
Do you have an email address or website where I schedule to bring my 2019 blazer in ??

It’s the thermostat
Did you drain any antifreeze before? Also did you bleed the coolant after you finished? Thanks.
Yes and yes
Thank you much appreciated.
I just want to know how you removed the coolant sensor.
Stubby flex head ratchet wrench
Crows foot
do you need to drain the coolant in order to do this?
Yes and no you don’t lose a lot of coolant taking it out but will make a small mess if you don’t drain it
May i ask why your replacing the thermostat? What was there original issue?
P0128 thermostat dtc really common causes various issues, no ac, and service steering assist message
@trydecaddyz6831 did that fix there issue? I have a 2019 chevy blazer same exact problem with mine steering assist disabled temperature is all the way on cold fan runs constantly no ac then check engine light comes on then all of it goes away.

I had this done on my Acadia Denali $1680 in December 2023. I also had the coolant temp sensor replaced too at the same time.
Do you have the part #?
What backscrew pull the pole back
hidden 10 mm swivel ratchet wrench and a mirror make life easy.
Great info! 💯🔥
i always forget about the hidden 10 mm bolt lol.

How you know it’s the thermostat
Temp gauge doesn’t work plus other symptoms, it’s probably the wiring to the thermostat though as replacement doesn’t always fix
@@aelius_audio there is no wiring going to the thermostat. so i would think it would be the temperature sending unit or temp sensor, no?

Never showed how to take off other to censors to the right

Yep done with chevy myself
Do you have to empty out the coolant to swap the thermostat?
Yes
