My 86 325es runs hot - at higway speeds, the temp gauge is in the upper half of the spectrum. Add some steep hills or the hot desert sun and it actually goes in the red and I have to blow heat inside my car to keep it from overheating.
I recently noticed that I can't remember the last time the auxilary fan (In front of the radiator) turned itself on. Is there any way to test this fan?

cool. Where is this resistor?

You would think that at higway speeds, you'd have enough airflow, regardless of fans, to keep the engine in the normal range. The auxillary fan isn't for cooling the engine... although it helps a little. It's there to blow air through the condenser for your A/C.
I think maybe the problem lies elsewhere, but I hope it doesnt come to what nukeduster thinks it is.

Alright! New development: The AUX fan works when I turn on the AC, which means that the fan motor itself is fine. This leads me to believe that the temperature switches are bad, Does anyone have a link to a "how-to" on checking and replacing these switches?
