How to replace the A/C Accumulator in a air conditioning system on GMC C3500?

Begin by disconnecting the negative Battery Cable then recovering the refrigerant before replacing the accumulator. The system requires the removal of electrical connections followed by pressure cycling switch extraction. The dual o-ring tube separator tool (J 38042) serves to disconnect both the accumulator from the Evaporator while allowing the hose assembly to separate from the accumulator. First cap all open connections while you replace the o-ring seals, accumulator bracket screw, and accumulator with its associated upper and lower accumulator insulators. Installation begins with accumulator insulator placement followed by accumulator installation where you should add oil if replacing the accumulator. Fasten the accumulator bracket screw using 6 n.m (53 lb in) of torques. The new o-ring seals require application of 525 viscosity refrigerant oil before installation. First connect the Evaporator to the accumulator before tightening the assembly to 41 n.m (30 lb ft). Next, connect the hose assembly to the accumulator. Reinstall the pressure cycling switch along with its essential electrical connections followed by negative Battery Cable reattachment. The system needs charging afterward you should check for any leaks.
