Did this video help you?

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.

valerie9007: Thanks for the video. The bottom bolt does not have to be removed, only loosened. The housing is slotted for removal.

MonteLS: 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.

Drevan Darkbyrd: Would this apply for a 95 Buick Regal 3100?

MrEddieGwatz: I seen alot of post regarding the wrench that was used you can purchase one, or see if you can rent one from your part store it's called a "Half-Moon" wrench and it's a 13mm for this application. Wal-Mart has them for inexpensive. I'll include a link https://www.walmart.com/c/ep/13mm-half-moon-wrenches

this tool works too....

BiHlover80's: Its more difficult then you just explained . Also, the problem with bottom bolt is worst then viewers can imagine. If this was so "" easy "", why don't you record it , and make it possible for people to see it? There's a lot more to remove it to get access to the bottom bolt on thermostat housing. If this was easy job I believe you would show it to us as you did in some of your prior videos. Sorry man but sometimes we all have to admit when something is not easy even though it's not your fault it's the stupid GM engineer who design this engine. Thank you for shering anyway.

Bobby Stelpstra: You DO NOT need to fully remove the lower bolt, just loosen it a few turns.

DUNN RITE: nice but I like to take the throttle off way more room no bleeding knuckles
