Radiator and Cooling System- Page 1

I upgraded my cooling system from a 2 row mechanical fan with integrated transmission cooler to a 3 row radiator, electric fan controlled by a temperature sensitive electric switch, auxilliary transmission cooler, and a dash mounted fan indicator light. The old system overheated in a parade at Hot August Nights in Reno, so I upgraded it to a much more reliable system. The electric fan only operates if I am idling or driving slower than 15 mph for a few minutes.

Basic Radiator and Fan Setup

On the passenger side, in front of the radiator support and behind the grill, sits the transmission cooler positioned by brackets. The 14 inch Derale Tornado pusher fan is mounted in front of the radiator and just behnd the vertical radiator support. It was a tight fit and I had to trim about 1/2 inch from the vertical support.

Fan Switch Temp Sensor

This is hard to see, but the lower radiator return hose has a metal "T" with the temp probe attached at the bottom. The "T" fitting is steel colored, there is white teflon tape at the base, and the nipple is copper. I would have preferred to have the sensor in the top of the radiator (in the hose leaving the enigne and heading into the radiator) since that would be closer to the true engine temp, but the hose was not long enough for the "T" fitting. This method works just fine however.

Temp Control and Fuse

The variable temp control switch and 30 amp fuse are mounted behind the radiator support, ahead of the battery. Most of it is tucked under under the hood beneath the radiator support seal but it is visible from the rear of the car.
