The accuracy of these switches live a lot to be desired. I've tried many brands, and they all seem to have poor quality control. Either dont work or the temps are wrong. I've had them bad out of the box. Another died while I was on the emissions dyno. Luckily I caught it before the gauge got to the red and turned on the a/c.

That's another thing, if you have a/c, you want the fan to kick on when the a/c is on.

One thing to consider is placement. I could not put my switch in the head since it interfered with my headers, so I put in in the t-stat housing.

Here's the switch I have, AC Delco 14043275.
