Dash a/c ? non GMC
The compressor on my 1994 suburban is very noisy. I disconnected it so I can at least use the blower. It is a factory 134 system, with axial 4 compressor. I have been using Duracool for about 3 + years, with very good results.
A friend of mine gave me a good axial 4 compressor. However it was used in a Freon 12 system. I drained out about 1 oz of oil, but there is residual oil clinging to the inner surfaces that will not drain. I know the best thing to do will be buy another compressor. BUT money is tight. The good compressor is on the bench and the pulley can be turned by hand to make it cycle.
1.
Is there a chemical (that won’t hurt the compressor and the rest of the system) that can be put into the compressor, hand cycled and then drained, that will clean out the residual oil?
2.
Would the residual oil clinging to the inner surfaces be enough to damage the system when it mixes with the 134 oil?
