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 Heavy Duty Thermal Fan Clutch
  • Turns the fan 70-90% of the shaft speed when engaged for increased cooling
  • Turns the fan 25-35% of the shaft speed when disengaged
  • Used with deeper pitch fans (2-1/2" of pitch)
  • Land and groove design with up to 27 square inch of working surface
  • Identified by finned aluminum faceplate and thermal spring on the front
