I have an 85 previsouly tpi car.


I am now building my 355 monster...


Before i had my fans hot wired on all the time. but now i am thinking of devising a way to run it when it is needed.

I was thinking a thermostatic switch in the head, for the ground for the relay, but wouldn't it turing on and off so often mess something up early?

What would be the best way to keep it running as close as possible to 200* F?

I have the single fan, and i love the single fan.


what are my options...

 

Run it like the factory had it designed to be run. Grounding sensor in the head, grounding out the relay completing the circuit, powering the fan. Fan switches are available at various temperatures. Probably the cheapest way.

 

is that how the factory ran them? because mine never had a switch in the head. the fan was controlled via ECM...
