I'm puzzled by one feature of the fix. I believe the servo has a temperature sensing switch in the bottom which will not allow the fan to blow (and perhaps also not allow the aux water pump to run) until the coolant reaches a certain temperature. What happens with the switch when the servo is bypassed? Wont the blower not operate? How have people solved this problem? Bypassed the switch somehow?
Also does bypassing the servo cause any problems with the controls calling for some action which cannot be carried out since it cannot sense the temperature of the coolant? Could this burn out the amp or control panel?
