Chevrolet Cavalier: Have a 1991 Chevy Cavalier 2.2L 4cyl. ...there

This answer was rated:

Have a 1991 Chevy Cavalier 2.2L 4cyl. ...there was a leak in the a/c and I fixed it. There is no R12 left in the system due to the leak. To recharge, I need to attach a retrofit kit. But not sure which are the high and low ports. Could you tell me where each are? If you have a pic, it would be great.

Usually the high side port is on the thinner pipe and the low side on the thicker pipe.

You have to vacuum the system, too before you add R12. I assume you knew that.

Let me see if I can find some pics or diagrams. BRB.
