1992-2003 Ford Taurus (excluding SHO Models) A/C Bypass Pulley for V6 3.0L

This part replaces:

  • DORMAN 34166

This Bypass pulley bolts on to your engine in the same location as your malfunctioning Air Conditioning compressor, allowing you to use your original serpentine belt. A malfunctioning compressor can be noisy and cause premature damage to your serpentine belt. This is a cost effective alternative to costly repairs to your Air conditioning system.


  • Built to strict quality control standards
  • Includes bracket, highest quality bearing, and correct size pulley
  • Fits perfectly in the place of an A/C compressor.
  • Allows you to use your original serpentine belt
  • Fits 3.0L V6 engines excluding SHO models with the Yamaha Engine
