Way to bypass AC compressor pulley?

Post by ketchup3821 » Tue Oct 01, 2019 10:46 am

Hey guys,

2001 V70 2.4T with 193k on the clock.

Background: car has no functional AC because some well-meaning guy in a pickup truck destroyed my condenser and radiator last winter trying to pull me back onto the road. I had the radiator replaced but didn't realize the condenser was killed until this summer when I tried to run the AC. So that's fun.

This weekend, my serpentine belt broke. I replaced it. It broke again. Something on that side of the engine appears to be louder than it should be.

I replaced the belt again, and took it to the shop next to my office. They say it's the AC compressor locking up and shredding the belt. They also say I need to replace the AC compressor in order to fix this. As the car already doesn't have AC, this feels dumb since it would cost a grand (or $2300 to do both that and the condenser). I don't have the space to replace a compressor myself.

Is there any other way to get this car going again? I can't find anything about bypassing the AC pulley but that would be ideal.

It seems like the compressor clutch is engaging at idle even when AC is off. Could that be all that's doing it? Can I pull the fuse/relay and make that stop? I'm at my wit's end here. I don't care about the AC ever working again, I just want to be able to drive the car without shredding a belt.

Thanks.

On previous 5 cyl cars (94-98), it was possible to bypass the compressor with a shorter belt.

With the 99+ later cars, I don't think you can:

There is a thread on swedespeed on bypassing the compressor but it involves removing the AC compressor and replacing it with what appears to be a idler:
