Hayden makes four different types of thermal fan clutches; Standard, Heavy Duty, Severe Duty and Truck Fan Drives. Each type is engineered to simulate the performance, fit and appearance of the original equipment clutch that it replaces. All fan clutches are for specific applications and should only be applied for which they are cataloged. Use of the wrong fan clutch may result in poor cooling, excess noise, reduced mileage, or fan clutch failure.
