FAQ18 - Why doesn't my cooling fan turn on by itself and why doesn't it stop running?
Your thermostat fan switch, which is threaded into the rear of your radiator is dead or shorted out. Simply buy a new one. Dead wire at your own risk! You just might get caught in summer heat with a broken manual switch in the middle of a freeway or short your battery out with a faulty manual switch. Neither is practical.
Replacing the original automotive switch may just save you a lot of unnecessary memory work, overheating problems, as well as the risk of being stranded. We offer our aftermarket thermo fan switch for models 1975 to 1987. |
