A/C Compressor Bypass Pulley

Your A/C compressor is activated from inside the cabin by a switch. This switch sends power to the A/C clutch, which is driven by the belt. If your A/C clutch locks, but your compressor doesn't spin, this can damage your belt and may leave you stranded. If you're not ready to replace a damaged A/C compressor or clutch, consider an A/C compressor bypass pulley. The pulley bolts in place of your compressor to retain your belt routing, but the belt only spins the pulley rather than powering the faulty compressor. If you need a compressor bypass pulley, check out the options at O'Reilly Auto Parts. We also carry replacement A/C compressors, clutches, belts, and tensioners to help you complete your repair.
