WARNING: This page is about a different car, the 2005 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If the A/C accumulator is being replaced, add 120 milliliters (4 fluid ounces) of refrigerant oil to the refrigerant system. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.

If removed, position the accumulator into the retaining band and loosely install the bolt.
Position the accumulator and retaining band into the slotted hole of the support bracket on the dash panel.
Remove the tape or plugs from the opened refrigerant line fittings and the accumulator ports.
Lubricate new rubber O-ring seals with clean refrigerant oil and install them on the refrigerant line fittings. Use only the specified O-rings as they are made of a special material for the R-134a system. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
Connect the refrigerant lines to the accumulator.
Install the nuts that secure the refrigerant lines to the accumulator. Tighten the nuts to 9 N.m (80 in. lbs.).
Tighten the bolt that secures the accumulator retaining band to the support bracket. Tighten the bolt to 4.5 N.m (40 in. lbs.).
If removed, install the A/C low pressure switch onto the accumulator using a new O-ring seal. Hand-tighten the switch securely.
Connect the wire harness connector to the A/C low pressure switch.
Reconnect the negative battery cable.
Evacuate the refrigerant system (Refer to HEATING & AIR CONDITIONING/PLUMBING - STANDARD PROCEDURE - REFRIGERANT SYSTEM EVACUATE) .
