Auto Air Conditioning & Heater Repair: olds ac recharge, olds aurora, ac recharge

Question
I have a 1997 olds aurora v8.I'm trying to add refrigerant to the ac system. Where is the low side service port located? Thanks.

Answer
IF you have to add freon then you have a leak that needs to be fixed and then the system has to be evactuated of ALL air BEFORE you can add freon and this requires the use of a vacuum pump.

The valve is located on the accumulator (receiver/drier.
