Review on 🌡️ Enhance Cooling Efficiency with Derale 18748 180° Thermo Switch for Electric Fan by Adam Rogers

Revainrating 5 out of 5

Five stars are good for switch

Works great. Hook it up to the fan relay ground wire and it will last a lot longer than if you tried to pass full positive amps through it. It barely fits in the radiator core of my 2003 Ram.
