Air conditioning compressor pulley noisy when air conditioning is off. Would like part no. of serpentine belt used on engines with no air conditioning.
Sometimes there is no listing for a serpentine belt for a vehicle w/o AC. That’s because the manufacturer never produced that vehicle w/o AC.
Are you suggesting that you want to just replace a belt and eliminate the noise? I would warn you that it may not be that easy. You might need to do a little more than just eliminate the AC and change a belt.
