Answers;

1. 8 oz. sounds right.

2. PAG 46 is correct.

3. Flush the compressor by removing it from the car. Add some flush, rotate, and drain everything you can using gravity. Follow up with a good dose of dry air to evaporate any flush remaining. Repeat until no oil residue is carried out with the flush. Very important to not leave any flush in the system since it will contaminate the refrigerant.

4. Flush the evaporator both ways. Flush until it flows clean. If you are only going to do it in one direction, then go reverse flow. The expansion valve must be removed before flushing the evaporator coil.

5. I cannot confirm the refrigerant quantity but the 126 systems use 2.9 lbs. so 2.85 sounds like the right number. I have the charts with the numbers at my office. I will check tomorrow.
