Mark Vlll fan...
Charles, I think it would be a great upgrade-here is a quote I have from the service manual for a Mark Vlll-1997.
"PCM determines when fan operation is required by monitoring coolant temperature, vehicle speed and air conditioning status. When operation is required, PCM signals VLCM to turn on fan to desired speed."
This doesn't actually point to a voltage control, but maybe the computer controls it along with fan speed. Thoughts, anyone? -Jabin
