Please tell me more....I've been thinking about this for 2 weeks.....Mystique runs hotter than I like in hot weather, slow traffic...when I'm traveling at highway speeds, with good air flow, the gauge shows R-M, but when I'm traveling slow, with poor air flow, the fan only kicks on when the gauge is at the L... ..

It appears that the thermostat attempts to keep the engine at one temperature, but the fan only kicks in at a considerably higher temperature. I would like to install a switch or thermostat that would induce the fan to operate at a temperature closer to the thermostat temperature. I'm leaning more toward a thermostat than a switch, but I'm leary about goofing up the PCM.

Thanks.
