A thermal fan clutch links the engine-driven cooling fan to its drive and responds to temperature. As temperatures rise, it engages the fan more firmly so the fan moves more air through the radiator. At lower temperatures it slips more, which is designed to reduce fan drag and noise.
Four Seasons engineers and tests its products with years of trouble-free operation in mind, backed by more than 50 years of mobile A/C experience.
Reverse rotation: this clutch is made for fan drives that turn in the reverse direction. A fan clutch's rotation must match the vehicle.
Signs a fan clutch may need replacing include rising temperatures at idle or in stop-and-go traffic and weak A/C cooling at idle. Others are a fan that roars constantly, a fan that wobbles, or a fan that spins too freely by hand with the engine off. These symptoms can have other causes, so diagnose the cooling system before replacing parts.
