Thank you so much for this video. A mechanic refused to work on our 2021 blazer because he said it was too hard to change the temp sensor on it, and i wanted to find a video to see if he just didnt want to help us or if it really was hard. Your video helped a lot thanks again.

watched like 7 videos trying to determine if this is something I could handle, and every one other than this one made it seem way over my head. you definitely have the easiest approach here.
Is this video just to replace the thermostat or does it also include the temperature sensor? I am going to be trying to do this on Sunday. Your video is great! Thank you!
You welcome and thanks for watching, the video is just for the thermostat but to be honest i never have to replace temp sensor on your engine it is usually the thermostat
Get a cheap scanner that reads live data and then drive and monitor your coolant temeperaure and it should read between 160-190 degrees and if it fluctuates while driving then your sensor is working and doesn’t need to be replaced
My daughter has a 2019 Blazer that started acting up last week, the internet says it's the thermostat, could it be one the other, or should I change both??...from Wyoming USA 🇺🇸 👋🤠
@@billallen4793usually just the thermostat is the issue, especially if the temperature gauge isn’t working. People have replaced thermostat and temp sensor just to have the issue reappear. If thermostat doesn’t fix it’s the wiring to the thermostat is getting too hot because they left unsleeved
Yes, ,not way around it but it is not as bad as it look , as matter of fact, the manual want you to remove the fuel injector rail which require a special tool and time
@@steevegmtech7326 I just did this and you're right, it's not even that bad. The hardest part is removing that 10mm bolt that holds the pipe in place. Super easy if you tear up the foam but harder if you want to keep it intact.
I just done this yesterday took me just 2 hours with refill up coolant Leave the pipe in change the oring unplug battery first Crows foot the unloosen sensor Also I put small amount of silicone sealant back around small o rings All is well 💪🏿🛠️🧰
Okay so I’m stuck at the part where you take out those injector lines at the thermostat. I am wiggling and tugging but they will not pop out at all. I’m nervous to clamp down too hard on the metal part with pliers in case of pinching or breaking. What can I do?
At that point i would just buy them in case they break in the head,happen to me before luckily they were readily available at the dealer, also spray wd40 before attempting removal
My daughter has a 2019 Blazer that just started acting up last week! It's supposed to go to the shop for diagnostics tomorrow. The internet says it's the thermostat, could it be both, one or the other, should I change both to be safe? Any help would be extremely appreciated...from Wyoming USA 🇺🇸 👋🤠
@@steevegmtech7326 thanks i just replace the temp sensor after a month code p0128 came back ... now im gonna replace the thermostate this week, i hope fix
Thanks for the video bro! Our Mechanic is about to check our car since we have this 👉🏼Steering Assist is Reduced Drive with Care, and hopefully he can fix it 😕

He is an inexperienced mechanic if he refused that job but did you a favor because he would probably break something

This video save me a lot of $$ thank you so much for the detail.
You welcome 👍
Thanks for the video. Got mine changed in about 5 hours. And I had to take that foam out it makes it easier to get to the pipe screw.
You welcome, I'm glad I was able to help ☺️

@@steevegmtech7326 Thank you! Kind of nervous to take the car apart but I feel better tackling this job since your video is so thorough!
Trust me it look intimidating, but it is not you got this , don't overthink it

Thank you 🇺🇲
You welcome 👍
There is a tsb. Gm techs were originally replacing electric racks.
Hey bro it’s me again, thank you very much, I fixed my car today, I only need to erase the check engine light 😢. Thank you very much ❤
You welcome man, I'm glad it worked out for you,thanks for the support
Damnnnnn that's a lot of work for just a sensor....
Not as bad as it look
P0128. There is a tsb on this. Many vehicles are still under warranty.
There is no tsb on that, if your vehicle have warranty,yes it will be covered

@Pinoy915 any advice on how to do it without tearing the foam?
I just done this yesterday took me just 2 hours with refill up coolant
Leave the pipe in change the oring unplug battery first
Crows foot the unloosen sensor
Also I put small amount of silicone sealant back around small o rings
All is well 💪🏿🛠️🧰

I’m about to attempt this myself. But I have no idea how much fluid to let out. I don’t want to drain all of the coolant.
Lol it will drain itself once you take the thermostat out 2gallon 50/50 mix dexcool should be fine

Most likely the thermostat, very common issue on those
The engine temperature meter isnt reading just stays on cold even after a drive
I bet you your cooling fan is always running, and your ac is not working, you must likely have a bad thermostat or temp sensor
@@steevegmtech7326 yes the fans are loud and haven’t tried the ac because it’s cold outside
@victornunez307 try to unplug the battery and plug it back in,to see if it went back normal
I am unable to get the pipe out of the thermostat. The pipe is loose and I can wiggle it but it wont budge from the t-stat.
The o ring is probably stuck in there,use a little of wd40 , it might help
@@steevegmtech7326 I used a pick to get in and grab the O-ring after I commented. It came apart afterward. Thanks for your content.
you fix the dtc p0128 with this job or still the problem ?
Yes the thermostat replacement fixed it
@@steevegmtech7326 thanks i just replace the temp sensor after a month code p0128 came back ... now im gonna replace the thermostate this week, i hope fix
@@rikastars did you bleed the system correctly?was the bottle full
@@rikastarsDid replacing the tstat fix the P0128?
@@user-jd5sj8jx7r yes i replace the thermostat and temperature sensor then clear the code with launch scanner
What’s the book time on this?
About 3.5 or 4hr
@@steevegmtech7326 thank you sir!
you skip the most important part.
Which part did I miss?
@@steevegmtech7326 probably referring to how you have to wiggle the thermostat in and out of that tight space. you just cut those parts out.
Thanks for the video bro! Our Mechanic is about to check our car since we have this 👉🏼Steering Assist is Reduced
Drive with Care, and hopefully he can fix it 😕
That's most likely your problem, it is an easy fix
@@steevegmtech7326 great! Just curious, how much do they charge to do this job?
@@audiasRodriguez roughly 3.5hrs
@@steevegmtech7326 this thermostat that you shared with the link is for Chevy blazer 2020?
Yes it should
