Have you looked for fan switch setups at Summit Racing or Jeg's? This is what Patcon is referring to: Electric fan controller Sildes between the fins of the radiator, or could be mounted alongside, but should be in the airflow. Just noticed that this is preset at 185, but they make similar that are adjustable.

I might try an adjustable one out and see if I can fit it in between the shroud somehow. Thanks for the clarification!

billgtp Posted January 1, 2022 Share #16 Posted January 1, 2022 (edited) I have the twin fans on my 71 240. I used a thermostat housing from 280z to mount a sensor for my fans. Fans come on at 180 and off at 220. Also hooked to relays so they come on when a/c is turned on. You have webers on your car so your thermostat housing should work fine. I purchased a temp sensor and taped the housing for the threads. Lower sensor is for fans. Edited January 1, 2022 by billgtp correct temperature settings on 220 off 180 (104c on 82.2 c off 2 Link to comment Share on other sites More sharing options...

And please put a F after it as we euro's don't know Mr Fahrenheit.. we use Mr Celcius hahaha.. (That is always fun.. celcius Fahrenheit.. kelvin.. but the most fun is foot and meters.. there were made A LOT of mistakes.. someone bought a boat in the states, thought it was meters and found it very cheap.. he got the boat... in foot... ) (people with more examples, make a extra topic, don't want to make this one a mess..;-) ) Btw, nice solution to use another th.housing for a extra th.switch!

My 3.1L stroker stays cool on the street here in hot and sunny Myrtle Beach. The controller is adjustable and was from Jegs or Summit. It's worked well for several years.

I guess I will have to tap out the threads for the sensor. Found the lower left hole is a m14x1.5 npt and no sensors are made to fit that. Question, why do you have the fans coming on at 220F? Isn't that a little too hot? Link to comment Share on other sites More sharing options...
grannyknot Posted January 1, 2022 Share #21 Posted January 1, 2022 Most of the aftermarket controllers are adjustable, they are preset from the factory but there is usually a small white slot screw. I tweaked mine to on at 200F, off at 180F 1 Link to comment Share on other sites More sharing options...
billgtp Posted January 1, 2022 Share #22 Posted January 1, 2022 It could be a little cooler. But I will try this and see what happens this summer. I like my engines to run warm. Link to comment Share on other sites More sharing options...
w3wilkes Posted January 2, 2022 Share #23 Posted January 2, 2022 I bought the dual fan, shroud and 3 row radiator from MSA. It came with a Auto Cool controller. The temp sensor is like a foil thingy that wedges between the radiator output and the hose. I believe this is where the coolest water is leaving the radiator. 1 Link to comment Share on other sites More sharing options...
billgtp Posted January 5, 2022 Share #24 Posted January 5, 2022 Ownallday you got me thinking that is high. Pulled my receipt out on sensor. It comes on at 200f and off at 180f Link to comment Share on other sites More sharing options...
