Quoting 5OF2k:
what??
Your fan switch should tell the fans to turn on at 203*, and will run until the car gets back down to around 195*(IIRC...doublecheck your FSM for verification). Your FSM will also give you a detailed fan curcuit run-through and different points and specifications to check against your setup in order to help you repair/rectify the issue. Now, with different engine management setups, fan operation can change dramatically, so in essence we basically need to know mor information, and you should look into finding the specifications for the fan, switch and so-on ti ensure the circuit is in optimal oerating condition.
Does that make sense?

Actually, the fan switch is set to a much lower temp, since it sits at the bottom of the radiator. I don't remember the exact temp. But when the fans kick on, it's usually around 203 on the datalogger.
I think there is also a switch on the thermostat housing that kicks both the AC and radiator fan on around 230something.
