#4015, "RE: radiator fan not on at idle" In response to In response to 3
just take the thermostat out and drive it without it. Your car has never run so cool! BTW, on 1g 4G63's, the Thermostat doesn't tell the fans when to come on, this little sensor thing does that screws into the side of the thermostat housing. A thermostat can't tell anything, it's just a mechanical spring that opens once it reaches a certain temperature.
