If you are referring to the low pressure valve for charging the air, I found mine (1988 pickup) somewhat deep in the lower front left of the engine. The low and high pressure valves on my pickup were very close to each other and the low pressure valve points inward (toward the driver). There is about 2" of clearance above the valve port which makes it immensely frustrating to charge, especially with a R134a conversion kit. The conversion adapter cuts your clearance down to about 1", and almost all recharge cans have a hose so short you can't even turn the can upside down or shake it. Plus, everything around the port gets hot enough to burn your fingers when the engine is running. I found a R134a extension hose at Auto Works but it didn't work with the conversion nipple, the freon wouldn't go through. I finally located a R12/134a angled converter from Napa Auto Parts for around $7 bucks, but I noticed the R12 screw on doesn't have a pin in it to open the valve. Apparently you have to remove the valve core stem on the port. I can't find any article on the web that says yes or no on that, and nobody at any auto store knew either. I bought a valve core removal tool at Napa just in case also and am going to try both ways tonight. Going on my 2nd week attempting to charge the air. What a nightmare.....at least its been under 90 degress out lately. Hot and Burned
In the engine, usually in an oil pressure port
