For general care, wash with a mild detergent. and water. Rinse and polish with a soft, clean. cloth until dry. Baking soda on a damp cloth. should remove any gummy buildup of soil. To remove burned-on grease from a electrical. appliance, use whiting moistened with amonia or. denatured alcohol.
Fan Clutch What Is It and Whats it Do. The fan clutch is an automatic device that is often used in a vehicleâs cooling system. So, when the engine is cool or even when it is at a normal operating temperature, the fan clutch will partially disengage the engineâs radiator cooling fan (which is mechanically driven).
The air temperature passing through the radiator is sensed by the bi-metal thermal spring on the front of the thermal. fan clutch. It expands and contracts with the change in air temperature operating a valve inside of the clutch. This. valve works as a gate to a reservoir containing silicone drive fluid inside the clutch. When cold, the silicone drive fluid. is pumped from the working area to the reservoir. When hot, the valve opens allowing fluid from the reservoir to. be transferred to the working area thereby increasing the fan speed.
