This trick electric fan switch is a normally open temperature switch with 3/8" NPT male threads that screws into your intake manifolds water passage. When the coolant reaches 185°-215°, the contacts on the cooling fan switch close, activating a relay which directs current to your electric fan. When the engine cools, the contacts on the fan relay switch open, and the fan stops automatically. This radiator fan switch arrangement is not adjustable, but is more rugged than other temperature fan switch setups.
NOTE: This thermal fan switch must be used with a fan relay. If installed as a gounding fan switch, it will burn out. We suggest using this temperature fan switch with our relay 910-64044. Make sure the fan switch is mounted in the manifold or radiator tank so that the bulb is submerged in the HOT engine coolant.

I was having issues with my electric cooling fan. It was powered all the time through the key switch. This part fixed that issue, now the fan turns on when the temperature calls for it.

Do I need a flyback diode to work with this? I plan to use this as a ground trigger to the relay controlling the fan. The fan pulls about 30 amps but the fan sensor would only see the current needed to close the relay.
