Can anyone tell me how to replace the ball type high and low service port valves? Can i use an adjustable wrench?"
More importantly, Anyone know if these can be purchased (on ACKits, local parts store, or elsewhere)? Having trouble even finding them online, yet alone in the local Auto parts stores
I purchased a High & Low-side R134a Service port leak repair kit which contained a install tool and two small silver schrader screw-in type valves. Unfortunately, i noticed that the high and low ports actually on my car have what appears to be a black (rubber maybe) check ball in the ports (instead of a silver screw-in valve). Looks like the port housing itself is threaded into the hose fitting and can be removed, however i noticed that none of my wrenches (metric or standard) fit the fitting size.
Thanks for any help, insight.

Im pretty sure you have to replace the lines,I believe those are non servicable..

You can replace the service port on those with the teflon ball..I don't have the Ford part number handy, but any dealer should be able to give it to you..To take the old one off, (make sure you have the new one first..) just use a plyers or vice grips as you don't care if you damage the old one.. Then use a small adjustable wrench when you put the new one on, or ask the guys at Ackits.com if they have the service port wrench available..it's a special socket for replacing the service ports.. I'll try to get the part number for you..
Opps, I forgot that was the one that stands up by the condenser..You do need to change the line..Below is a pic of it with the AcDelco part number..Hope this helps..

AcDelco part number is 15-31356 It didn't show in the pic.....
I'll try to check into this a little further tomorrow, as it "may" be replacable..Or at least one of them... Sorry, can't do much more from home..

Chick: Thanks for the helpful info on this. If you find out for sure that would be great. They appear to be threaded in and removeable. Although they may not have been leaking from the ports, the line has been sitting out of the car for a while and would be safe and replace them prior to charging up the system.
I replaced the plastic caps on my Tahoe with brass caps that have an O-ring. Problem solved. No more expensive replacing of valves.
