C.C.O.T. REFRIGERANT OIL DISTRIBUTION

1. With no signs of excessive oil leakage, add:

d. Accumulator

R-4 Compressor - Remove, drain oil, measure, replace same amount of new oil plus 60 mi (2 fl. oz.) to compensate for that retained by the original accumulator dessicant.

DA-6 Compressor - Remove, drain oil, measure, replace same amount of new oil plus 90 mi (3 fl. oz.) to compensate for that retained by the original accumulator dessicant. If no oil can be drained from old accumulator, add 60 mi (2 fl. oz.) new oil to the new accumulator.

2. With signs of excessive oil leakage:

DA-6 Compressor Systems

Remove only the accumulator. Drain, measure and record quantity of oil in accumulator. (It is not necessary to remove and drain the DA-6 compressor because the compressor only retains a minimum quantity of oil, it doesn't have an oil sump area.)

If less than 90 ml (3 oz.), add 90 ml (3 oz.) of new oil to system. If more than 90 ml (3 oz.), add the same amount of new oil as drained. If a new accumulator must be added to DA-6 system, add 90 ml (3 oz.) additional oil to compensate for that held absorbed by the original accumulator dessicant.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
