Product Details

The Four Seasons 45914 is a direct-fit idler tensioner eccentric arm designed for serpentine belt drive systems. Engineered as an OE-quality replacement, this eccentric arm adjusts belt tension by offsetting the idler pulley position, ensuring consistent, proper tension across the accessory drive belt system.

Key Features:

  • 1.75-inch (1-3/4 in.) offset for precise serpentine belt tension adjustment
  • Steel construction with satin finish for corrosion resistance and long-term durability
  • Meets OE specifications for a direct-fit, no-modification installation
  • Helps prevent belt slip, squealing, and premature belt wear
  • Sold individually

A properly functioning eccentric arm is essential for keeping the alternator, water pump, power steering pump, and A/C compressor operating correctly. The Four Seasons 45914 is backed by over 50 years of automotive parts expertise, delivering a reliable, long-lasting repair.
