I seen a video from other guy and he made it so easy pulling up the thermostat without taking any part

[advancedleveldiagnostics]

Wow, that job looked like a pain! Thanks for sharing!

I just take the intake off. Crazy tho at a dealer labor and parts for this job is 1100😂

My mother just purchased 2019 gmc acadia & it's not even a week old & this problem has occurred 🤦‍♂️. I'm pretty sure warranties will cover but I feel like the dealership had to see this issue 🤷‍♂️

Anyways thanks for this awesome video 👍👍

Yay I get to do this repair this weekend. Do you need to drain all the coolant or just let whatever comes out of the thermostat drain?

[MDPBF]

what would you recommend if everything you have in the vid is happening but the reservoir is empty (hot- after driving and cold- after sitting for hrs)?

[billallen]

Are those little pipe o-rings special, or will any o-ring work? Do you have a part number for all the intake and pipe o-rings, gaskets, ect!..from Wyoming USA 🇺🇸 👋🤠

This is exactly what my 2019 gmc acadia denali does. And the fan is so loud when the ac doesn't work. Sometimes I can get it to work by revving the engine up real high but it only last a few days then its back to no ac and a loud fan.

[cameronbeard]

This is likely a dumb question. What’s the downside to buying an OD2 scanner and just clearing the code since this issue is more of an inaccurate “glitch”??

My daughter has a 2019 Blazer that just started acting up, it's supposed to go to the dealership tomorrow "monday" the internet says it's the thermostat, could it be the temperature sending unit? Should I change both, could it be one or the other? Ect! I'd appreciated any help with this i can get! 80, 000 miles, no warranty it ran out a little bit ago! She just bought it used last fall, after totalling her new Bronco hitting a deer...smh..from Wyoming USA 🇺🇸👋🤠

How many bolts approximate or how hard to remove the manifold to access this thermostat? What is the name of the manifold you removed?

[cz]

Wow thats absolutely absurd for a thermostat replacement. Can you tell me approximately what that job costs to have done?

[dull_boy_]

do you have a part number for the bleed pipe o-rings? I can't find them anywhere

[christiandavis]

Just had this happen on my wife’s Acadia tonight. Riddle me this, why does the AC also not blow cold when this happens?

[jeremiahnichols]

Engineers don't think, "Hmmm is this going to be insanely difficult to repair?" The more and more I look at this engine the more I'm thinking to stay away from this thing completely.

We just replaced the coolant sensor in my 2019 Acadia - and the code is coming up again. Should we replace the thermostat??

[ricardohz]

I can't find anything on the 2017 acadia 2.5l to replace the thermostat

[thomaszimmerman]

just replaced the ect sensor and thermostat on my 2018 3.6 canyon and my truck still will not get up to operating temp any ideas?

[Peter_Riis_DK]

What about the shuddering torque converter - any result on that?

[chandlerlofton]

I haven’t seen an air ratchet in years!
