Anyone know what the stock thermostat temp is on an EA82? My car has an OE thermostat in it and is majorly overcooling. Now that it's below 40 out, the needle barely gets off the line, and I've got hardly any heat. Basically I need to know if getting the 195 degree thermo from the auto parts store is going to change anything.

 

And no, the electric fan is not running.

oe should be 192, what radiator do you have?

Has a regular double core EA82T rad. Thinking of replacing the Tstat anyway, perhaps could be stuck open now? Easy enough for me to just take a look, at least.

 

Coolant is ciculating like crazy, I can hear it gurgling through the heater core whenever the car is running. This car has the best cooling system I ever had, after flushing the rad over the summer.

Yeah, sounds like a stuck thermostat to me. Either get one from the dealer or get a Stant "Superstat". I've used both and they're about the same quality, which is way better than anything else.
