How do I by pass aircompressor

Is the belt a V-Belt?

If so- then you have bolts you can loosen to
move the compressor or other accessories

If it is a single serpentine belt, I don't see the problem

If the compressor hub or pulley still turns, you leave the
compressor there & just have no a/c

The truck is too old to be spending money with bypass
kits & such, for no reason.

If the clutch hub has a locked up bearing, replace it, if the a/c
would still work?

The compressor cannot be by-passed, but you can disconnect the compressor clutch by disconnecting the two wire connector at the compressor; then the compressor pulley is just an idler.

There's probably no way to find a serpentine belt to by-pass the A/C compressor. However, the compressor only spins when the compressor clutch is engaged, and if you unplug the clutch the compressor pulley spins freely on its bearing without turning the compressor. The clutch wiring connector is usually on the compressor near the pulley.

It sounds like the belt is slipping or maybe even the compressor is seized. Just check to see if the compressor is turning.

There is not one,but napa auto parts sells a by pass pulley to replace the ac compressor and you use your same belt,it cost about 39.00 around here.If this was at all helpful,please rate thank you.

No. The bearing on the compressor can be replaced without buying an entire compressor.

This problem sounds like the aircompressor pully, the bearing is shot.
With the engine running and the air conditioner off there is a grinding noise, look at the compressor pully, does it wobble? Then turn on the air conditioner and the noise stops, look at the compressor pully again, the wobble stops? If so that's the problem.

Why bother, just pull the clutch coil plug and move on. When you sell it the next folks may want A/C .I would leave it.

The best way to do this is first ask the parts house to see if this car came with out air and get a belt that way. I dont think that year had the option of not havnig A/C. The other way is take a piece of rope and put it around the pullys just like you are puttin on the belt but by pass the A/C you might have to make a few trips or get a few different size belts but its the only way
