Accumulator HVAC: Service and Repair
Installation
INSTALLATION
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system. Failure to properly adjust the refrigerant
oil level will prevent the A/C system from operating as designed and can cause serious A/C compressor damage.
CAUTION: The A/C accumulator must be replaced if an internal failure of the A/C compressor has occurred. Failure to replace the A/C
accumulator can cause serious A/C compressor damage.
NOTE: When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be added to
the refrigerant system.
NOTE: If only the A/C accumulator is being replaced, add 30 milliliters (1.0 fluid ounce) of refrigerant oil to the refrigerant system. Use only
refrigerant oil of the type recommended for the A/C compressor in the vehicle.
NOTE: Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is opened. Failure to replace the rubber O-ring
seals and metal gaskets could result in a refrigerant system leak.
1. If removed, install the accumulator mounting bracket (10). Tighten the retaining bolts to 15 Nm (11 ft. lbs.).
2. Remove the tape or plugs from all of the opened refrigerant line fittings and the accumulator ports.
3. Lubricate new rubber O-ring seals with clean refrigerant oil and install them and new gaskets onto the suction line and accumulator 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.
4. Connect the upper A/C suction line (2) to the accumulator inlet tube (4) and install the retaining nut (3). Tighten the nut to 5 Nm (44 in. lbs.).
5. Install the retaining band (6) and bolt (5) that secure the A/C accumulator (1) to the mounting bracket. Tighten the bolt to 8 Nm (71 in. lbs.).
6. Connect the lower A/C suction line (8) to the accumulator outlet tube (9) and install the retaining nut (7). Tighten the nut to 5 Nm (44 in. lbs.).
