I'm trying to locate the low pressure service port on my 86.0. It isn't where it is located on my 79. Unlike the OB, there isn't nearly as much clearance to access a service port. My WSM's don't offer any guidance that I can find.

Have you checked for a service port where the upper radiator hose enters the radiator?

It's on the passenger side (US) right below the upper radiator hose. The low-side hose comes up from the compressor into a 90 degree fitting. The low side port is on the pipe right after that fitting, pointing straight up.

Look in the area under the radiator inlet hose, over towards the coil.

It looks like we agree.
