I was hoping to get some advice on what to do about a very poorly located low side service port. It is located right on top of the compressor which is buried down low in the engine compartment and the brackets holding the compressor make it virtually impossible to get a charge line on the fitting. It is possible to gain some room if the compressor is loosened and rotated towards the engine but then you can't run it because the belt is too loose. As I recall, the one time I watched a mechanic charge it was through the high side port with a fancy machine. I want to add a service port at an easier to reach location. Should I get a weld on port and add it to an accessible hard line section? Any suggestions on how to deal with this appreciated.
You can have in in-line service port installed via welding or placed in the rubber section.
If you don't have any leaks, I can't understand why you would need to add or check your R-12 more than like once every six-eight years. So is it worth it to you for that? Just asking...
Well I do have a leak or leaks and am also planning to switch over to R134. So it will involve taking much apart anyway. But it comes down to: if I want to do it myself how can I charge it if I can't get to the low port with the compressor running (belt tight)? Do they charge at the factory statically or something?
Now there is a part I have not seen in 15 years - wish I had a picture. Oh well, Tim can make you one from a description.
We called the part a "pigtail", and they were on the shelf before the 928's showed up. Came in handy on some SAAB's too as I recall.
Just a short (dash 4 size) hose assembly, with a 90 dgree flare fitting on one end, and a service port on the other. Installed permenantly, after removing the valve core on the compressor service port. The actual hose was about 18 inches long. Usually found cable tied off to something else in the engine bay.
