PT Engine Cooling Fan System
Rick:
There is an alarmstat on the rear of the engine that senses water temperature. When it reaches the correct temperature, it signals the fan to go into high speed. I don't know all the interlocking parts, but that typically is how it works. A failed alarmstat will keep your fan on high all the time. Also, when you turn on the dash air, it signals the fan to run in high mode. R.E.
