Adding Oil To Compressor

Year: 1991
Make: Lincoln
Model: Towncar
Engine Size: 4.6
Refrigerant Type: R-12

Hello All,

The compressor in my 91 Lincoln froze up due to a leak and loss of oil. I found the leak in the condenser and replaced it along with the filter drier. I brained a used compressor and am getting ready to check it out and install it. The used compressor has no oil in it and I understand from some previous posts that oil should be added through the suction port before mounting the compressor on the engine block. I also read that one must be careful so that the added oil does not result in 'slugging' the compressor.

I'd appreciate any comments or suggestions on what procedures I should use to check out the compressor and put in the proper amount of compressor oil before I mount it on the engine block.

Thanks

Dale

Dale-
Your vehicles capacity for compressor oil is 7oz. I would advice to pour in 5 oz into the compressor thru the suction port before mounting it, and the rest (2 oz.), into the drier right before installing it to distribute the oil throughout the system properly.

Just to add, the listed capacity is the total amount. So removal of all original oil is needed or you may end up with too much oil.
