Some background please - year and mileage and what engine.
Also why did you replace the thermostat? Was it running hot, or too cool?
Can you elaborate on how it "kinda looked like it was backing up" - what were you looking at to determine that? Was it warming up, or already warmed up? What does the temp show on the digital temp display?

Whopper.
rwatkins has his own thread in regards to the issue he's having. Check it out here: https://www.chevyhhr.net/forums/main...ing-fan-57374/
I think he was just checking for some alternate info by posting up in this 4 year old thread.

Except for the part where you said the cooling fan shuts off at 200*, it sounds like normal operation.
When you turn on the AC(or defrost, or recirc), the cooling fan kicks on, and should stay running until the coolant temp reaches 180*. If the AC(or defrost, or recirc) is off, the cooling fan turns on at 219*, and should stay running until the coolant temp reaches 180*. Did I get that right, donbrew?
So is your cooling fan still turning off at 200*?
