Man, you made hard work of this. I did it yesterday and it took about 2 min. 19MM ratcheting wrench. No need to beat on the exhaust, no need to pull the mount bolt.

[@lawrencedelrazo2271]

right man I just did it right now in 5 minutes I think I'm going to start making videos 🎉

[@jaywish9489]

Will this be the reason car would t start in cold weather

[@edwardwilliams4671]

Good video sir. It wasn't the easiest way but it was a blessing to someone who did not know how to get it off. Keep on sharing these video's. Some one always need help. It was a blessing.

[@n3iyr]

All you have needed all along is a Stubby Ratcheting Combination Wrench 19 mm. All you remove is the thermostat housing and hose. You will get two "clicks" out of the stubby 19. It's just enough to R&R the TSU. No damage to the heat shield or any other part.

[@jackharding98]

Thanks for posting this video. Your narrative had me feeling like I was right there with you in the dark, holding a flashlight for you or something. As a kid, I did plenty of that for my dad as he cussed his way through auto repairs. I laughed and learned, thanks!

[@kaelbryant7660]

I would highly recommend getting a set of craftsman swivels for each size ratchet! They are life savers for tight slots and pretty cheap!

[@jayzed3868]

Thank you so much for your efforts to show us how to do it. Appreciate it

[@EddieCorbijn]

I have to this on my 05 GP. I'm gonna look into a 19mm ratcheting wrench (120 tooth). Thanks for the info on how to do the job.

[@raychatman4698]

That's what I used!!! A helluva lot easier

[@davidsisk9013]

Lmao,that’s what kind of mood I’m in!I love it ,lol,brother I appreciate honesty man

[@padfinancial1781]

Ratcheting wrenches are always helpful in tight spaces. Not great for breaking a nut but once its broken lose they work well in tight spots where your socket will get back locked into another part of the motor.

[@raychatman4698]

I used a ratchet wrench, hand tighten it as much as possible, then use the box end ratchet wrench to tighten it, it's a 5 minute process, takes patience , but you'll get there

[@Nicole-dj3jf]

Is this the same as 3800 v6 5.3? I have a pontiac grand prix sedan 2008 dealer said 300 to do this job with part smh

[@michaelmiguelicutti2829]

@@Nicole-dj3jf What do you mean "3800 v6 5.3"? I think you're confused as to what engine you have. There is a 5.3 V8 option for this car from 2006-2008. Check under the hood to see if the engine cover says "3800 Series III V6" or "5.3L V8" and you'll know. If you have the V8 then this job very different, as it's a different engine.

[@Nicole-dj3jf]

@@michaelmiguelicutti2829 yes it's a series 3 it's parted aty mother I can't check if it has 6 or 8 spark plugs this dex shit is a night mare the antifreeze looks brown I need to do a super clean on the cooling system a few guys looked and they couldn't find the drain plug another guy said there is none and I'd have to take the bottom hose off to empty the old crap and switch it to another kind of antifreeze dex sucks ass fast engine way to big for the transmission

Best tip for a repair thanks wow your Pontiac has 280.000 miles mine has 230.000. I bought it new used 9100. Miles.

Thank you SO much for posting this, I am about to change mine on a 08 Grand Prix and just from looking I figured I better see if someone posted a video because it looks like a pain in the ass

[@georgevera7395]

Same lol

[@TheZehnerhjk]

Great video! Do you think Snap on or Mac make a coolant temp socket or a 19 that is designed for this????

[@46singledad46]

I looked at mine it doesn't look as bad as you say. Proper socket ratchet set .

[@46singledad46]

Lol.i plan on it m car has the same problem. They have proper ratchets that an swivel on that angle I'm sure.

[@Nicole-dj3jf]

Did anyone figure out the right tools to get the sensor out? I can't go in and get my hands dirty or have much tools as a female my tool set is getting bigger lol I need to change this sensor my car goes from normal temp to 3 notches above then drops to cool again while driving any help will be very helpful

[@jonmo2694]

@@Nicole-dj3jf get a 180degree thermostat.Or did changing your ETC sensor fix it? I have a ETC sensor code and my grand prix gets halfway hot when idle or at drive throughs, when I drive over 40 continuously it goes down, I thought my fans were not kicking on but it was I think, I'm going to flush the radiator change the sensor and thermostat to the 180 degree one.Hopefully that will fix the overheating deal.

So how did you know your sensor was bad did you throw a code or did you stop getting a read out on your temp gage

I have same question

[@stoneymitchell3821]

It could just be common sense 🤷‍♂️

[@46singledad46]

On my 04 Pontiac gran prix super charger i got a codeAI forgot the code but it said thermostat sensor. I hope I can get this part .anyone who has a Pontiac gran prix. They discontinued most parts.

Well done brother! So what led you to this shit show of a job? 280k annual preventative maintenance? My 04 heats up sitting still, I'm throwing a p0480 and my main fan doesn't come on until I remember to kick the AC on.

[@jonmo2694]

Dont know whats up , i changed mine twice and get a code for ect sensor, didn't you have to change the wiring harness out? Looks like the duralast.sensor i bought.What a shitty location under thermostat housing where it can leak and next to a zillion degree exhaust pipe! Coolant probably leaked on the wire housing or the exhaust pipe fried the wires?
