A/C Port Location
This is probably been answered before, but I can't find the answer using search. I have a 2002 Sierra 2500HD with the 6.0L gas motor. The a/c needs a recharge and I thought I would save some money by performing this myself. Problems is I can't tell where the "low" pressure port is to install the freon/oil charge.
I have two visible ports on topside of motor, both with black caps and both attached to the same metal pipe. The only thing dividing them on the pipe is a metal coupler. One port is a little larger than the other.
Which one do I use?
Any help would be great!

According to what I've heard as long as you keep the pressure within specifications you won't damage anything by topping it off. If a system leaks and you top it off you're not exceeding what the compressor was designed to handle.
I've got the same problem though I can't decide which one is a high pressure and low pressure port as they are within inches of each other. I have a GM service manual on the desktop computer upstairs I'll take a look later tonight and get back to you if there's anything in there about which is which...
EDIT: Couldn't find anything sorry man..
