Luis Garcia: hey guys, i just replaced my T. Today, the bottom bolt does not need to be removed all the way, i did id but u need small hands, if you don't, don't even try it,, it took me almost 5 hours, easier said than done, but definetely doable. i have a buick 3.1L saved me 150. 00

Aunt Ester: Thank you for the video. Ordered one of the below wrenches listed at Amazon listed below. Also went ahead and bought a set of the crescent shaped wrenches like the one you used at Harbor Freight today for about $18. Hope to tackle this job before summer. Thanks again

Marshall Foster: Best thermostat wrench save time and hassle

jc monteon: Thank you sir for sharing your knowledge.
Greatly appreciated!

hugh3rdof5: Hi Rich.... Am having to do this job for the second time on a 2000 Montana. Always appreciate your videos and your creative tips. Thanks to 13mm ratcheting wrenches, I managed to get off both both bolts this time, surprisingly easily. BUT (keeping me humble), once again, I'm unable to get the thermostat housing off, without more serious "surgery" on the patient. I'm rather amazed by your demonstration (at minute 2:45) that once you get the housing bolts off, it's then easy to slide the housing off. If only. Maybe for other GM vehicles, yet for the Montana/Venture, that exhaust wrap around seems too tightly situated on top of the thermostat housing -- preventing me from simply sliding it off. (the thermostat underneath makes it impossible to remove, or for that matter put a new one in) Like the last time, I suspect I'm going to have to take off the throttle body and the coolant bypass pipe.... (and even then, I wonder...)

Bill Melater: I see a number of people have commented on not completely removing the bottom bolt.

Bill Melater: Notice him removing the housing. About the 2:50 mark. It appears the bottom bolt does not need to come completely out. There is a slit in the housing where the bolt goes. I wonder if it could be loosened enough to be able to slide the housing off the bolt and away from the thermostat.

GarageWorkouts: I did mine today...It was a bitch..Thanks for the video richpin

Ryan Witkowski: Thanks for the walk through. It was a life saver

Danny F: I must state first that the reason for so many different videos regarding this issue is the very poor design of GM engineers.
This video helped me to do the job, however the coolant drain instructions, as shown here, is a bad choice. It is very simple to drain the coolant thru the radiator inlet. Remove the cap, insert a thin tube up to the bottom and draw the coolant to a large bottle/pan.

barry bleam: doing a themostat on a 3100 is abitch did one today and guy in video was working on a 3400 witch gives a little more room at the exhaust pipe to remove the housing on the 3100 you have take the sheid off toget the bottom bolt and yes you have to take it all the way out

Tim Donavan: whati fyou dotn have magic tools wtf. GM engineers need their throats cutt

Elegant Toilet: you sound like Fred Stoller.

valerie A: Thanks for the video. The bottom bolt does not have to be removed, only loosened. The housing is slotted for removal.

MintMonte: Never thought peter griffin would explain how to replace a t-stat

12345IMALIVE 54321YOURDONE: LOVE THE JERSEY ACCENT, " THAT WAS THE HAUD POT WRITE THAR LOL

12345IMALIVE 54321YOURDONE: i HEAR YOU CAN REMOVE THE THROTTLE BODY TO MAKE IT EASIER TO GET THE LOWER BOLT TO?

paul klein: this guy is full of crap. every thing he does that is difficult he hides. I just did this and it was a freaking nightmare

Joseph Wagner: The bottom bolt is pure evil. Thank God it's slotted.
