1990 164QV Euro spec & 1991 168B
Look on your POA valve for number(s). The R12 valve has J9D5A next to low pressure service fitting hex flat facing towards timing belt cover of engine.There has been reference in other posts to Eaton POA valves for the 164. Unfortunately, no Eaton part numbers provided.
I found a shop that has a variety of Eaton valves available. Does nanyone know the part number or a reference to vehicles that used the same one. I have a 95 164LS so it would be the r134 variant I presume it has metric fittings.
Hidden on back side hex flat next to inner fender is number 540 042.
I do not have a R134a valve to check numbers.
See if your number similiar.
Is this an Eaton number as no name on valve I have, so I don't know?
