Dorman - HELP A/C Compressor Bypass Pulley P/N:34274
Dorman 34163 A/C compressor by-pass pulley for the 1982-1987 Ford F-150 and other vehicles takes the place of a failed A/C compressor in the belt drive.
If a failed A/C compressor is behind a warm cabin or a noise at the front of the engine, this pulley lets the compressor come out while the belt keeps running. A worn belt tensioner, an idler pulley or the belt itself can be behind similar noises too, so find the cause before buying. Each vehicle needs one pulley.
Besides the 1982-1987 Ford F-150, this A/C compressor by-pass pulley fits the 1982-1987 Ford F-250 and the 1984 Ford Mustang, along with many other Ford, Lincoln and Mercury models.
