Re: Electric fan
Those are some pics of the 3.8 Taurus fan. I've had good luck with it in several trucks. It came on several cars in the early-mid 90's....the 3.8 Taurus, the 3.8 powered cougars, and some 3.8 powered lincolns I've found to have it.
A word to the wise if/when you install it....DO NOT run the low and high side togethor at the same time. This will create ALOT of heat in the motor, and it will start to melt things on you. Expect about a 30amp hit when the fan kicks on, and about 18-20amps continuous while running on high. The low side is slightly less than that, but still has a decent hit when comeing on.
I've found that wiring is somewhat simple by using a cheap thermostat from Autozone as the low side controller, and a simple switch in the cab. Using two relays you can make them both easily swithable, and controllable. Also if you have access to chipping software/equipment, you could use the IC pump output to flip a relay for the low side, and the thermostat to flip on the high side. There are about 100 different way to wire it up, just depends on how you want it to run, and how your truck reacts to it. I have yet to find two the like the exact same settings.
