My AC stopped working and I did some looking around fuses good, ac system is charged. I noticed a rattle on the compressor pulled at the same time I noticed my serpentine belt was really cracked. Got the belt changed but they didnt want to tighten it down due to the rattle in the compressor claiming it could break.

So now I have a squealing belt and no AC.


I have ordered a re-manufactured AC compressor with clutch and pulley

any tips on replacing it, can I do it myself? Is there a how to by any chance?

Replacing the compressor is straight forward, but evacuating and charging it will require bringing it to a shop.

The Air Conditioning section of the service manual shows the step by step of replacing it. You can download it from the Micro Image Forum:

cant charging be done with the recharge kits at any autoparts store?

I bought one with a guage thinking mine was low so I have a full large bottle and gauge

Those are "kind of OK" for recharging a system that is a little low, but not good for an empty system that has been exposed to air. The moisture and particulate that got into the compressor and system while disconnected will cause very premature failure if you simply charge the system without evacuating it. The evacuation process involves using a suction pump to draw an extreme vacuum on the system, which removes any moisture and impurities.
