How to replace the A/C Accumulator in an A/C system on GMC C2500?

The replacement process for the accumulator begins with a recovery of all refrigerant from the system. Start by removing the electrical connector from the a/c low pressure switch along with the compressor hose fitting from the accumulator. The installation sequence begins by removing the evaporator fitting's nut and then the accumulator bracket nut from the retaining stud before taking out the accumulator. First disconnect the retaining bracket bolt then take off the retaining bracket from the accumulator before you remove the o-ring seals. Installation begins with new o-ring seals followed by retaining bracket attachment to the accumulator while installing the retaining bracket bolt then tightening the accumulator bracket bolt to 10 n.m (89 lb in). Install the accumulator first followed by the accumulator bracket nut with a torque setting at 9 n.m and 80 lb in. Install the nut by bringing it to the evaporator fitting before adjusting torque to 16 n.m (12 lb ft) and finally install the compressor hose fitting and electrical connector to the a/c low pressure switch. The system requires addition of refrigerant as you conduct a j 39400-a leak test on all fittings of repaired system components.
