Most people are well aware of the mechanical clutch that is in their transmission, and some people are aware of the magnetic clutches that are on their air conditioning compressors and their alternators. However, not many people are aware of the clutch that is part of the fan blade. The Flexalite fan clutch is designed to replace your worn out fan clutch, helping to keep your engine running at the proper operating temperature. A fan clutch such as the Flexalite fan clutch is operated by temperature. When your engine is cool, the oil within the clutch allows the fan to spin independently of the engine speed, so it will not cool the engine, allowing it to come up to temperature rapidly. When the engine heats up, the oil changes viscosity, and the fan will begin to spin. The Flexalite fan clutch is a great solution to a fairly complex problem. A failing fan clutch will either fail to engage the fan or it will engage the fan at all engine temperatures. Replace your worn out fan clutch with a brand new Flexalite fan clutch.
