Does anyone have a procedure for replacing the expansion valve on a 92 Loyale (EA82)? I'm nearly certain that this is the cause of the over-pressure poor cooling problem. The system has been evacuated and recharged with the correct amount of R-12 but shows very high pressure and at idle, cycles the compressor because if the over-pressure condition. At higher rpm or while moving, the ac functions but not very well. I think this is a partially plugged expansion valve but not certain. It looks difficult to remove and a procedure would really help. Thanks in advance.
