Mopar Performance 68064284AA Viscous Fan Clutch

The Mopar Performance 68064284AA is a genuine OEM viscous fan drive clutch, also known as a fan clutch or clutch-fan drive. This thermostatic engine cooling fan component freewheels at low temperatures when cooling is not needed, then engages as temperatures increase so the fan is driven by engine power to move air and cool the engine.

How It Works:

The viscous fan clutch connects the engine's cooling fan to the water pump shaft using a special silicone-based fluid to transfer torque from the engine to the fan. The input and output sides have mating concentric grooves with silicone oil between them, and the amount of oil in this grooved space is controlled by a valve connected to a thermal element located at the front of the fan clutch. When engine temperature rises above the engagement temperature setting, the fan becomes fully engaged, drawing a higher volume of ambient air through the radiator to maintain or lower engine coolant temperature.

Key Benefits:

• Saves engine power since the engine does not have to fully drive the fan at all times
• Improves fuel efficiency by reducing power consumption, as the engine doesn't have to work as hard to drive the fan constantly
• Allows the engine to warm up faster by freewheeling during cold starts
• Essential for reliable engine operation, especially in hot weather conditions
• Backed by the manufacturer's 12 month, 12,000 mile warranty

This genuine Mopar part ensures reliability and factory condition performance for your vehicle. In the event of fan clutch failure, prompt replacement is important to prevent engine overheating or damage to the water pump, pulley, or belt.
