Bleeding/burping coolant system
Well I am going to be replacing my thermostat and coolant temp sensor this weekend, I was searching and can't find a good answer about how to bleed/burp the coolant system on the H3 to get the air out after I swap them.
Also, could I just remove the old thermostat quickly and throw the new one on quick while its leaking fluid out to keep from draining the whole system and filling it with air?
Thanks,
Spencer

No need to worry about air in the cooling system of your H3, irrelevant.
Sure you can pull off the old Tstat and quickly put on the new one, just were a swim mask and snorkel.
Seriously, you pull off the lower radiator hose (you should have a round nose radiator pliers to make it super easy) and drain it into a bucket. Then do the Tstat with a couple towels handy. Then refill with Dexcool. You will need about 1.5+ gallons of coolant (red Dex only) to refill so either buy 2 Gal. 50/50 mixed, or 1 Gal. and mix in distilled water for your 50/50.

For more visuals on the radiator drain process, look at this efan related thread where I posted some details. https://www.hummerforums.com/forum/h...version-32647/

When the time comes to do my tstat, that's exactly what I'll be doing.
