fan clutch
A fan clutch is a small, fluid coupling with a thermostatic device that controls a variable-speed fan. The fan clutch ensures that your fan will continue rotating at just the right speed to keep your car engine from overheating and it also reduces drive to the fan when it is not needed. Filled partly with silicone oil this functional clutch is designed to reduce the wear on your fan.
When the temperature of air passing through the radiator rises, there is a bimetal coil spring that is alerted to uncoil or expand. When your fan clutch coil expands, it allows just a little more oil to enter the fluid coupling so the fluid coupling starts to rotate the fan. Of course, the opposite happens if the air moving through your radiator is cool.
You will see improved fuel consumption when the fan clutch engages, as it reduces fuel consumption and makes less noise and saves your engine power. Many merchants online can ship to you within 24 hours at remarkably low prices compared to your neighborhood parts depot. Finding just the right fan clutch for your vehicle has never been easier. Happy shopping!
