For my '96 302.

I've never worked the A/C on this truck before, but it's clear that it has a slow leak because it isn't blowing near as cold as it used to...so here I am.

I found the high side near the radiator on the driver side, but for the life of me I can't find the low.

I did find a capped nipple over near the receiver drier, but the cap is on so tight I didn't want to remove it unless I was sure that's the low side.

Can someone tell me where the low side is located?

Thanks.

i think thats it. black plastic cap.

Right after I saw your post I ran across this diagram on another forum of a 94 system. Mine looks like the diagram.

Thanks!

Low side is the one next to the dryer...If it's on tight chances are the rubber in that schrader valve is leaking....

If so, is the schrader replaceable like on car tires? Or is it a specialty item?

Maybe the PO sealed the cap with something then screwed it on tight.

All the o-rings should be buna-N (green)

If that's the case, do you know of a source for the o-ring? I'm guessing it's not a standard item at Advance.

Edit:
Never mind...I see that you CAN buy the schrader and new cap at Advance. Imagine.

Thanks for all the help guys, I really appreciate it.
