How Do I Find The A/c Port To Add Freon?
I have a 1992 Buick Regal. I had the a/c compresser replaced this winter and did not have the a/c recharged. I wanted to add the freon/ recharge it, but I don't have a manual and cannot find the port. Everything online says to just look for the plastic cap but I do not see one. Thanks

First find the A/C compressor, it is attached directly to the engine and has a pulley on it. When you turn on/off the A/C while the engine is running you should be able to locate it by listening for it to engage.
When you find it you need to trace the two metal pipes that come out of it. One pipe is the high pressure side and one is the low. You will know which one is the low side when you find the 'tee' with a plastic cap (both high and low have one).
The fitting that comes with the A/C recharge kit will only fit properly on the low pressure port. Sometimes, but not always the low pressure port has a blue cap.
