Refrigerant Oil Distribution

Compressor systems require 240 ml (8 fluid ounces) of polyalkylene glycol (PAG) synthetic refrigerant oil (GM P/N 12345923 or equivalent). During component replacement and conditions stated, new oil quantities should be added to the system as follows:

^ Compressor replaced.

- If less than 30 ml (1 fluid ounce) is drained, add 60 ml (2 fluid ounces).
- If more than 30 ml (1 fluid ounce) is drained, add same amount.

^ Receiver and dehydrator/accumulator replaced.

- Add 30 ml (1 fluid ounce) more than what was drained from old receiver and dehydrator/accumulator.

^ Evaporator replaced.

- Add 90 ml (3 fluid ounces) oil.

^ Condenser replaced.

- Add 30 ml (1 fluid ounce) oil.

Upon replacement of a component which caused a large refrigerant leak, add 90 ml (3 fluid ounces) of new polyalkylene glycol (PAG) synthetic refrigerant oil (GM P/N 12345923 or equivalent) plus the required amount of oil for the particular component (as outlined above).
