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 120 milliliters (4 fluid ounces) of refrigerant oil to the refrigerant system. Use only the refrigerant oil of the type recommended for the A/C compressor in the vehicle.

NOTE: Replacement of the refrigerant line O-ring seals is required anytime a refrigerant line is opened. Failure to replace the rubber O-ring seals could result in a refrigerant system leak.






NOTE: LHD model shown. RHD model similar.

1. If removed, install the A/C accumulator (10) into the accumulator bracket (8) and position the accumulator and bracket into the engine compartment as an assembly.

2. Remove the tape or plugs from all of the opened refrigerant line fittings and the accumulator and evaporator ports.

3. Lubricate new rubber O-ring seals with clean refrigerant oil and install them onto 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.

4. Connect the A/C suction lines (9 and 11) to the A/C accumulator and install the retaining nuts (1). Tighten the nuts to 12.5 Nm (110 in. lbs.).

5. On LHD models, connect the spring-lock coupler that secures the rear section of the A/C suction line to the A/C evaporator (6) and install the secondary retaining clip (4).

6. On RHD models, connect the rear section of the A/C suction line to the A/C evaporator and install the retaining nut. Tighten the nut to 12.5 Nm (110 in. lbs.).

7. Install the two nuts (7) that secure the accumulator bracket to the dash panel (5). Tighten the nuts to 4.5 Nm (40 in. lbs.).

8. If removed, install the A/C low pressure switch (2) onto the A/C accumulator using a new O-ring seal. Hand-tighten the switch securely.

9. Connect the wire lead and connector (3) to the A/C low pressure switch.

10. Reconnect the negative battery cable.

11. Evacuate the refrigerant system.

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

13. Charge the refrigerant system.
