Re: Electric fan and aluminum radiator questions 250 straight 6

I don't want the fan to run permanently, but I also don't want to mess with the temperature switch.
I'm thinking that I should put a switch in the cabin and/or connect it to something like the brake lights.
Maybe there is something else I can connect it to in order to automatically turn it on/off?
Any thoughts/opinions?

That's way to high even on a BB motor. You want them to kick on around 195*. Are you sure that is the correct setting?
I have mine wired though the external adjustable temp senor in the fins to come on at 195* hooked to a relay straight off the battery. It is also hooked to a micro switch with a paddle to cut off at 35 MPH since you don't need the fan on at high way speed.
Link is for the adjustable switch.

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!
LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
