Replacing AC system on 1990 Corvette

by Ron
(Grafton, WV)

Just bought my first Corvette. A 1990 Convertible with L98 engine. The previous owner had started replacing the AC system components. He took out all hoses, accumulator, and had put in a new compressor. He gave me all the new parts when I bought the car. I replaced the condenser, accumulator, and all the lines. I know I have to add 8 oz of mineral oil to the system (R12 system). I have the oil but don't know for sure where to put it in the system. The manual says add 3 oz to the compressor, and put the rest in the accumulator but I don't want to make any mistakes at this point. Please give me specific instructions on how to do this part of the job?
