Product Details

The Gates 39120 Drive Belt Tensioner Assembly is a precision-engineered automatic belt tensioner designed to maintain proper tension on serpentine drive belts throughout their service life. This OE-quality tensioner helps ensure optimal belt performance and prevents premature belt wear caused by improper tension.

Key Features:

  • Automatic spring-loaded design maintains constant belt tension
  • OE-equivalent construction for reliable fit and function
  • Precision-machined pulley and bearing assembly for smooth operation
  • Heat-treated components for durability under engine bay temperatures
  • Reduces belt noise, slippage, and premature component wear

Gates tensioners are manufactured to strict quality standards and are designed to restore proper belt drive system operation. This tensioner assembly includes the pulley, bearing, and spring mechanism needed for installation. Regular replacement of the belt tensioner is recommended when replacing serpentine belts to ensure proper system performance and prevent unexpected belt failure.
