Coolest fan switch available?

[scampbel98]

What is the lowest temp fan switch available for the radiator?
I'd like to put in the lowest possible _ I'm running hi compression pistons and seem to be running hotter than I'd like.
I've used a manual switch to override it but want something a bit more automatic.

Thanks

here's one that you can install that adjustable from 150 to 240....

Mark Allison sells an adjustable fan controller. I have it on my car and it works beautifully

tartan, can you show where you installed the sensor on yours? i cant decide how to do it. Had the thing laying around for months, lol.

You can see the sensor just behind the upper radiator hose (driver's side, upper left side).

[MrJD]

And thats all you do, just (for lack of better term) stick it through at the upper hose?

Yep ... it is that simple. Just push the sensor into the radiator -- the fins will hold it in place.

Here is a link to the one I used: It is a little touchy to get adjusted just where you want it. I paralleled the original wiring so either the new switch or the original switch can turn on the fan.

I purchased it on line but don't remember from who. Have been using it for years.
