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.
Features & Benefits of Standard Thermal Fan Clutch
Varies the fan speed with temperature of the air behind the radiator.
Engaged (high speed) operation provides maximum cooling.
Disengaged (low speed) operation provides fuel savings and noise reduction.
Greater life expectancy than a non-thermal clutch.
Briefly engaged at cold start-up.
Engages at about 170° radiator air temperature, (about 30° lower than coolant temperature).
Benefits of Purchasing a Complete Kit
Do the job right the first time with the added benefits of a complete Water Pump & Fan Clutch Assembly:
Extend Life & Protect Your Engine: The water pump and fan clutch operate on the same shaft and wear at the same rate. Replacing one without the other may cause inefficient cooling operation or premature failure of the new replacement part.
Save Time & Money:The cost of the complete assembly is often less than buying the Water Pump, Fan Clutch and installation hardware individually, and replacing all of the components at the same time means you only have to do the job (or pay for labor) once.
