Keep your engine's accessory belt turning after the air-conditioning compressor gives out with the Dorman - HELP A/C Compressor Bypass Pulley (34190). This bypass pulley takes the place of the A/C compressor in the belt path, giving the drive belt a smooth surface to route over so the remaining engine accessories can keep spinning. It installs as a direct-fit replacement for the 1991-1993 Lincoln Town Car, 1992-1993 Ford Crown Victoria, and 1992-1993 Mercury Grand Marquis.
Bypasses the A/C compressor: reroutes the accessory belt around a failed or removed compressor.
Maintains belt routing: provides a pulley surface for the belt to ride on so it can continue driving the other accessories.
Direct-fit application: designed to install on the listed vehicles.
When an A/C compressor seizes, it can bind the belt and take down the accessories that share it. If a failed compressor is the cause and you don't plan to replace it, this bypass pulley lets the belt keep driving the remaining accessories. Signs you may need it include a seized A/C compressor or a belt you can no longer keep tensioned around the original compressor. Diagnose the cause before ordering.
