Autopart International 1604-520411 Engine Cooling Fan Clutch

The Autopart International 1604-520411 is a thermal engine cooling fan clutch designed to regulate engine cooling fan speed based on temperature. This fan clutch automatically engages and disengages the engine cooling fan to maintain optimal engine operating temperature while reducing parasitic horsepower loss and improving fuel efficiency.

Key Features:

• Temperature-activated thermal design for automatic fan engagement
• Helps maintain proper engine operating temperature
• Reduces unnecessary fan operation to minimize power loss
• Direct replacement for worn or failed OE fan clutches
• Engineered to meet OE form, fit, and function

Fan clutches are critical components in engine cooling systems, particularly for vehicles with mechanical belt-driven cooling fans. When the fan clutch fails, it can lead to engine overheating or constant fan operation. This replacement unit restores proper cooling system operation and helps prevent engine damage from inadequate cooling.
