CAUTION!

DO NOT flush R-134a refrigerant system
with R-11. R-11 is not compatible with
refrigerant R134a and PAG oil and will
cause total system contamination.

If the compressor is not replaced after

flushing the system, fill compressor with the
correct type and quantity of refrigerant oil
specified under A/C system capacities

Page 87-141

. Fill compressor with the total

system oil capacity.

If the compressor is replaced, do not add

additional oil as the total amount of oil
required is already in the compressor.

Dispose of contaminated refrigerant oil

following laws governing hazardous waste
disposal. Do not combine any refrigerant oil
with any other old oils such as engine oil or
transmission fluid.

Follow all applicable Warnings and Cautions

when working on the A/C system
