If you want to get constant reliability and high performance from your vehicle's cooling system, equip it with only quality parts such as the 4 Seasons fan clutch. This is a thermostatically controlled device that engages and disengages the engine's mechanically driven radiator cooling fan. This fan is mounted in front of the water pump and is driven via a belt and pulley that are connected to the crankshaft. If the engine is at its normal operating temperature, the fan clutch partly disengages the radiator cooling fan so as to maintain constant temperature in the engine. This greatly saves power since the engine is not obliged to fully drive the fan. However, when the temperature in the engine rises above the fan clutch's pre-determined temperature setting, the fan fully engages in order to draw in higher volume of cool air though the vehicle's radiator. This also helps to maintain and lower the engine coolant temperature to a manageable level. Most 4 Seasons fan clutch are viscous couplings that are equipped with a bi-metallic sensory system which is similar to the thermostat. This fan clutch is fairly reliable and trouble free but sometimes it also fail. Indications of fan clutch failure are overheating at idle, poor AC system performance, and failure of the heating system to supply sufficient warm air.
