Re: electric fan temp switch?

Dang...I cant find my catalog or I would give you a part number but they are 3/8" NPT temp switchs that screw into either a intake manifold port or head port, just like where you would put a temperature sensor for a gauge. When the engine reaches a certain temp it complete the circuit, when the temperature lower to a certain temp it opens up and shuts the fans down. There are (2) versions; one comes on at like 185 and shuts down at like 170 the other one is a higher temp. Give Old Air a call they are easy to deal with and I believe the sensor is about 22.50.
