• Q: How to Service and Repair an A/C Accumulator on 2005 Jeep Grand Cherokee?

  A: Before servicing or repairing the A/C accumulator, pull out the refrigerant from the refrigerant system and disconnect the negative battery cable. Take out the grille, air cleaner housing, and air inlet tube. Then, unfasten the nut connecting the A/C liquid line to the A/C accumulator, separate the A/C line, and properly dispose of the dual-plane seal. Unscrew the nut keeping the A/C accumulator secured to the A/C condenser, remove the retaining screw that secures it to the radiator/fan shroud, and disconnect the A/C accumulator from the condenser, tossing out the dual-plane gasket. Put tape or plugs over the fitting for the A/C accumulator, the port, and the condenser port so that nothing gets inside while you're working. When mounting a new A/C accumulator, pour 30 milliliters of compatible refrigerant oil into the coolant. With the A/C accumulator positioned in the engine compartment, remove any tape or plugs from the A/C accumulator fitting and port; also remove any from the port on the A/C condenser. Apply a small amount of clean refrigerant oil to a new dual-plane seal and work it onto the A/C accumulator fitting with the recommended type of seal designed for an R-134a system. Link the A/C accumulator to the far end of the A/C condenser and tighten the securing nut to 20 N.m. Connect a screw to the A/C accumulator and secure it to the radiator and fan shroud, making sure to tighten that screw to 5 N.m. Use clean oil on a new dual-plane seal and attach it to the A/C liquid line, then fit the securing nut, tightening to 20 N.m. Restore the air cleaner and tube, plus the grille, and place the negative battery cable back on. After that, evacuate the gas and then charge the refrigerant parts.
