Followed procedure in FSM which closely matched the Sanden instructions, so I *think* the oil charge is right.
The old compressor didn’t detonate. It just leaked. No sign of debris in hoses or accumulator (replaced accumulator with new).
97 burb with front and rear air. Had both on full, the system would only take just under 2 cans.
With engine at idle and compressor engaged pressures were: 86/130, clutch disengaged: 89 both (high side looked a hair lower, but probably same just scale is difference). To me sounds like either orifice tube isnt working or rear TXV is stuck open? No restriction, just free flow of refrigerant. The tube between the office and evaporator is getting cool, so I’m thinking maybe rear TXV?
Does that make sense or am I maybe missing something else I should be checking?
If it is TXV any tricks to get one unstuck? I was going to replace it for good measure several years ago when I first repaired the AC but didn’t put the new one on because I was afraid of twisting the tube before the threads broke loose.
Thanks,
Mike
