I just noticed that my car will take like 20 mins of sitting to get warm, I start driving and turn on the heater, and pretty soon my air goes from warm to not warm, and my temp says absolutely cold again. Then I turn off the heater and drive. It slowly warms back up (without ever getting up to normal opperating temps) and then when I turn the heater back on it goes back to cold.

You think this could be a thermostat issue or maybe it's just stupid cold here (in Mn) and that's why I'm having problems?

 

sounds like your thermostat is stuck open steve... running ni thermostat did the same thing in my car...plus your ******* is frozen to your seat out there in hick ville

 

ya hotrex i think your right my z6 was doing that, ---- even when i would go down hills in the summer my temp would go all the way cold i was like wtf, it was just stuck open.

 

T-stat.

 

I thought that might be it, but I just bought this car and the douchebag who had it before me had a mechanic change the thermostat and radiator in 5/04. The mechanic was kind enough to write that in my engine bay with a marker, so the thermostat should be new.

 

He may have put in a lower temp T stat. They usually come in 192(stock) 180, and 160. Put a new stock type in and you will be set. The Stant T stats come with a new gasket on them. 15 minute job.

 

I wish I could have found that one. I had to search through a pile of rubber gaskets until i found the right one, and then I wasn't even sure it was the right one. ------- Checker Auto parts........

Then I remembered that when I installed this motor, I didnt even look to see if there was a thermostat in it.
