Product Details

The Hayden Automotive 2851 is a premium fan clutch engineered to regulate engine cooling fan operation for optimal thermal management. This thermal fan clutch automatically engages and disengages based on engine temperature, ensuring efficient cooling when needed while reducing parasitic drag and improving fuel economy during normal operation.

Key Features:

  • Precision-engineered bi-metallic coil for accurate temperature sensing
  • Heavy-duty construction for reliable long-term performance
  • OE-equivalent fit and function for direct replacement
  • Pre-filled with high-quality silicone fluid for consistent operation
  • Reduces engine load and noise when full cooling is not required
  • Thoroughly tested to ensure proper engagement temperature range

Hayden Automotive fan clutches are designed to meet or exceed OEM specifications, providing dependable cooling system performance. This direct-fit replacement restores proper engine cooling fan operation, helping prevent overheating while maximizing fuel efficiency and reducing unnecessary fan noise.
