I tried a search and could not find what I was looking for. I once read that some people are running sec. fan switches from Grand Nationals because they kick the fan on earlier. Does anyone know at what temp? Also what years and engines would I need to know to get one from a parts store. Thanks...

BTW, I HAD a Jet switch and it made my sec. fan come on after the car would be on for about 2 min. at idle or whatever from cold. Then it would never go off. If the car was warm at all, the fan would always be running. The primary fan worked fine, just like it should have. I checked everything else and determined that the switch was bad...Not too impressive for as much as those silly things cost...
