After replacing my A/C compressor (Saiko Seiki equivalent) and receiver dryer on my ’94 e36 (08/1994), the local shop refilled the system with refrigerant and retested the PSI levels. The PSI levels raised from 110/110 to 125/150, which led the technician to advise expansion valve replacement. So, I ordered the part from Pelican.com (#64118384379) and had the system evacuated again.
Following that, I removed the glove compartment and glove compartment support frame back at home. Next, the two screws supporting the right-side control module carrier were removed and the plastic valve cover was removed afterwards, finally exposing the valve itself. The flange bolt on the top of expansion valve was exceedingly difficult to loosen due to excessive corrosion. It was at this point that I hit a wall. I’m not sure as to how to proceed regarding the removal of the expansion valve mounting screws (if there are any, even). The copper pipes that extend out from engine compartment really inhibit any movement of the valve itself. Any advice as to how to proceed will be greatly welcomed. Thanks.
