My fan used to come on for about 3-5 minutes after driving. I have since changed to a 160 therm, and it has been a lot cooler out, but i noticed my fan NEVER comes on after driving, even after long trips on the highway. What is the factory setting for the fan to come on? my car usually runs at about 180, so is my relay bad? is there a way to be sure?
 
It depends on your chip. I believe the stock thermostat is 190 or 195, so the factory chip should not turn on the fan until higher temp, possibly 200. ?? Not sure. Let it idle and watch the temp until it turns on OR it gets too hot for comfort. Also, I believe high speed switch triggers ~210.
