[66AC]

I have my pusher fans on their own circuit with their own switch on the dash. They do not come on in a thermal switch sense, I simply have to flip a Lucas toggle and they come on. In this setup, it "gives me something to do" especially when coming into slow or stopped traffic. It also adds another switch to the dash which, personally, I like.

How effective are they? Quite. I can see the water temp hold or even lower depending upon the outside temperature.
