Flex-a-lite Part# 31147-Adj. Temp Sensor
Turns fan on/off at the desired temperature. Dial-adjustable 180-240F. Gives the freedom to set one temperature for occasional high-demand use, then reset for highway or day-to-day driving.


This is the one I use, works great!!

Case, you might try Old Air Products. They have (2) sensors that come on at different temperatures and screw directly into a coolant port. They are out of FT Worth right off of 35W, that may be an option if you happen to be around that area.

Cool! Do you mean they screw into the drain plug on the radiator?

Re: electric fan temp switch?

i thought i read somewhere you could use a temp sensor from an 80 something firebird that screwed into the manifold. I am getting ready to do this in the next few days as well

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.

Re: electric fan temp switch?

Painless makes a sending unit that screws in the intake or head. Summit & Jegs sells them. The part number for the 185*/170* is PRF-30111 . I use it and it works good. The ground wire from the relay runs through it.
