11-21 Ford 6.7L Powerstroke Water Pump Gasket - BC3Z8507A

FAN CLUTCH ASSEMBLY 

fits 11-19 Ford 6.7L Powerstroke Diesel Trucks

 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 Severe Duty Thermal Fan Clutch

• Turns the fan 80-90% of the shaft speed when engaged
• Turns the fan 20-30% of the shaft speed when disengaged
• Used with deeper pitch fans. (2-1/2" of pitch)
• Land and groove design with up to 72 Sq. In. of working area
• Larger working surface provides cooler running and longer life expectancy
• Thicker body and deep finned faceplate dissipate more heat
• Can be used in place of many heavy-duty clutches

• Poor cooling at low speed but good cooling at high speeds
• Poor air conditioning at low speeds
• No increase in fan noise when engine is hot

Manufacturers recommend inspecting your Water Pump and replacing it (if needed) at the same time you replace your Radiator Fan Clutch. The parts are connected by the same shaft, and a loose or damaged Radiator Fan Clutch can also cause the Water Pump to fail.
