Thanks to everyone who helped me with the diagnosis of my A/C compressor problems. The problem is with my A/C compressor clutch and pulley. I have a 2000 5.7 liter Chevrolet express work van with 157,000 miles. How do I change the clutch and pulley? I have looked at it and I can't tell how it comes apart. Do I need a special tool to get the clutch off the A/C compressor shaft, and can I make this repair without taking the A/C compressor off the truck? I really don't want to lose my freon if I don't have to.

 

I believe you can get a puller from KD tools at NAPA for that, and should be able to remove it on engine. If you have the room for the tool to go into place.

 

Marturo is right.

Might be more cost effective to change the compressor and clutch as a unit as the front seal might be bad with this much mileage.

How do you drive 150k in two years? Lol.
