Where is the Low Pressure Hose???

[Kimbrough]

...On the a/c compressor for an '88 GW? The upper hose or the lower one?

Thanks!

should be the upper hose. And it may have "suction" stamped on the compreesor itself where the low pressure hose hooks up.

It's the upper hose.

Also, I believe you have to screw the valve in (clockwise) to open it. I spent the longest time trying to open it the wrong way the other day.

Drat, and I knew that one.

High pressure hoses (2)are connected to the condenser. The low pressure hose connects the evaporator to the pump.. ;) .. ds..
