How to replace the A/C Accumulator on 2010 Cadillac STS?

The first step to change the air conditioning refrigerant desiccant is refrigerant recovery. Start by removing the front air deflector before taking out the A/C accumulator plug where you should note the PAG oil loss to check the total system amount. Proceed to eliminate the A/C accumulator then put in the fresh replacement A/C accumulator. The O-rings should receive lubrication before installing the A/C accumulator plug with a tightness of 2.9 Nm (26 lb in). Return the front air deflector then bring down the vehicle. Introduce the required oil amount before conducting an evacuation then recharge of refrigerant. You should examine the fittings of the component through using J 39400-A to test for leaks.
