Anyone ever get a smell of hot burning rubber when driving at slow speed w their hummer? Heat gauge was up close to 3/4. Wondering if the thermostat might be going out? Thanks I’m advance for any suggestions! 😊

Wait is this Ladner BC?

This is a river

Whoa! 😂

the reason you go through the wheel well is so you can check for leaks while running engine if you go the alt route and find a leak you will have to remove alt again

When you say "15 mil", do you also refer as "9/16 sae " or jus 9/16? Curiosity jus killing me....

Is there more to this story?

We just bought a used one and the sunroof on it has been sealed up. Guessing that it had been leaking. How would we take the sealant off and repair? Just wondering if you can offer any suggestions. Thanks

Just did my 2007. Went in through the wheel well. You need locking pliers to get the retaining ring off. Pull the hose off and bend it out of the way. Use a universal adapter for your socket and a few extensions. It's tight but with the universal you can get around the alternator. Reassemble and tighten with a torque wrench. The universal adapter is the key. Took about 1.5 hrs. Best of luck to those looking for answers.

Did you ever find the gear, if where did you find it? I need one myself. Great video.

Great Video Mr. Jackson. Thanks for helping us all out with this one!

I 3M sealed my sunroof and disabled the power switch, don't have time for junk, I love and thoroughly enjoy my 2006 black Hummer H3 now without the hassle of a leaking roof.

I’m 17 this took me forever to do took off fended and alternator

Hi... nice hummer.. Sorry to ask... whats size and ring are those tire and brand? can you give me the exact number for both... your look great! thank you!!!

Comes out through plastic wheel well

If you are going to attempt to do it through the fender well make sure you get some STURDY pliers with very very long handles. I've been at it for 3 days trying it through the fender well, I have bought two sets of pliers already and neither were sturdy or long enough. The reason is, you have very limited space, and the clamp is fucking strong af. So i am going to do it the way this guy did it because in my opinion if you dont have little arms and hands and have the grip strength of a strong man then you would be better off doing it the way this guy did. I swear wish I would have done it this way from the beginning I would have BEEN DONE. Through the fender is less work and not bad if you get the right pliers but then after that the top thermostat bolt is a bitch to get too. Have a small ratchet with an extension.

Hi there , do Hummer H3 have Thermostats with a Valve to Bleed them , if not then how did you bleed the air out of the Coolant System please ?

Hi which hummer engine is more reliable, old 3.5 or newer 3.7. Thank you.

Hmmm That looks like my truck. Oh wait, it is my truck!! lol Nice video! Curious, did you by chance do the grommet drill out procedure? So far since I've bought the truck from you, I've -removed the carpet and soaked it in a bathtub with bleach and water -repaired the rear left door open switch -aligned the fenders with the body -cleaned the hell out of the seats, headliner, plastics, etc etc -replaced some interior lights with LEDs -cleaned up some rust that I found under the carpet, used some rust converter and then bed liner all over the floor -removed that cb radio I'll never use :-) -fixed the rip in the headrest -freed up and lubed one of the tow hooks -replaced the sunroof gear -removed the headrest DVD players -fixed the adjustable headrests I'm loving every minute of it, I've got many many plans :-D Thanks again!!

Considering every little thing around hummer h3 costs a fortune, a gear in eBay fetching for 12$ sounds very reasonable! Thanks for video!

glad i don't have a sun roof.

if replacing it drop the temp 10 deg will run better..

Did you ever have a different reading on the heat gauge after replacing the thermostat ? i got the thermostat replaced and after it was replaced the reading was different. It was reading alot hotter than usual is that normal ?

I did this by removing the front tire way. My advice is to put the radiator hose on the new thermostat first making sure the holes on the thermostat line up without twisting the hose. I had my lower hose already on the bottom of the radiator but not tightened. Gotta tweak it. I tried putting the thermostat on first then trying to move that heavy duty hose clamp into place. Impossible.

He took the long route to removing the thermostat.

To much work! Trust me go in through the fenderwell. 20 min in and out.
