Fan clutches reduce the drain of engine power and improve the efficiency of a vehicle's cooling system. Fan clutches are fluid coupling devices which provide air flow through the radiator by using the water pump shaft to power a fan blade. Fan clutch replacement may be required when any of the following problems exist; Engine Overheating, Silicon leaking from fan clutch unit, Fan spins with little or no resistance (free wheels), Greasy build up at thermal spring or where shaft exits rear housing, Fan clutch vibrates on shaft or will not turn and Squealing noises from bearing.
