Hello all,
I have a '94 Ranger 4.0L. A/C system did not work on purchase, compressor would not engage. I decided to start by adding R-134a until system pressure was within specification, compressor came on as expected, cold air out of the cabin vents. I was really hoping I got off easy. Fast forward a few days of truck sitting, A/C compressor was intermittently engaging, upon removing both service caps I could feel/see/hear refrigerant escaping. Now comes my request for experience with these systems. As I understand it the service valves can not be replaced in this system, the entire hose assembly needs to be replaced. My concern is these valves have failed due to lack of use, no lubrication, cracking, and general degradation of the rubber o-ring components in the system. Should I move forward with an entire A/C system restoration, new hoses and o-rings, or would it be best to simply replace known leaking service port hoses and go from there? I thought it odd that both service valves are leaking, but I have very limited experience with A/C systems, maybe this is a common occurrence?
Anyhow, any knowledge or tips would be greatly appreciated!
Thanks!
