Engine Size: 3.8
Refrigerant Type: 134a
I have an 87 Buick. The original compressor had a leak at the shaft seal. I replaced it with a new compressor. I also replaced the accumulator and orifice tube. I flushed the system and vacuumed it down over night. The system is supposed to have 8 oz of oil, but I managed to put 10 oz in. It doesn't cool very well and the compressor cycles often and quick. Could I open it up, suck 2 oz out, seal it back, vacuum it then recharge?
Should be able to pour a good ounce or so out of the accumulator.
I pulled the accumulator and ended up getting right at 5 ounces of liquid out of it (4 ounces + 25 ml and a few drips plus there's a little still in it). That seems like a lot to me but I don't know. The original one didn't have much if any liquid come out of it. I'm thinking some of the flush may have been left in the system?
I plan to put in a new accumulator and orifice tube. The orifice tube was coated gray with sludge in it similar to how the original one was. Since it seems like some flushing solution was still in the system I'm wondering if this may be left over from the previous compressor failure? What should I do? When I put it back together should I add more oil?
You said you flushed, now you question if you did it right; the gray/sludge oil on the O-tube seems to validate your concern.
Read the paper in my signature below and answer your own question; did I flush it right?
I am sure this is not what you want to hear, but I am thinking you are going to have to start over.
That's fine. I need to know what to do so I don't have to do it again after this time.
