Fan clutches are thermostatic engine cooling components that allow engines to warm up or cool down depending on its operating temperature. Regulated by the opening and closing of a thermostatic spring, a flow of a viscous silicone fluid engages the fan clutch to operate at different speeds depending on the temperature, helping power consumption and saving fuel. Fan clutches will engage the radiator fan when the engine is hot, and disengage when it’s cool to save power. If a fan clutch slips, sticks or loosens, it may not be pulling sufficient air over the radiator to perform correctly and should be replaced, otherwise the engine may overheat. If you’re looking to replace your fan clutch, or want to make sure your car is in top condition, take a look at the ECP range below and enjoy free delivery or click and collect from the hundreds of stores across the UK and Ireland.
