If the A/C evaporator is being replaced, add 50 milliliters (1.7 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.
Make sure that the evaporator drain within the HVAC housing is clean and unrestricted and that the insulator is properly positioned.
LHD model with A/C shown in illustrations. RHD and heater-only models similar.
- Install the two halves of the HVAC housing (4 and 5) together and engage the plastic retaining tabs (4). Make sure the retaining tabs are fully engaged.
- Install the screws (2) and metal clips (1) that secure the two halves of the HVAC housing together. Tighten the screws to 1.2 N.m (10 in lbs.).
NOTE:
If the foam seal for the condensate drain is deformed or damaged, it must be replaced.
- If removed, install the foam seal (1) around the condensate drain located on bottom of the HVAC housing (2).
NOTE:
If the foam insulator for the evaporator is deformed or damaged, it must be replaced.
- Install the A/C evaporator (1) into the HVAC housing (3). Make sure that the evaporator drain within the HVAC housing is clean and unrestricted and that the insulator (2) around the A/C evaporator is properly positioned.
- Install the flange (3) onto the top of the HVAC housing (4).
- Install the four screws (1) that secure the flange to the HVAC housing. Tighten the screws to 1.2 N.m (10 in lbs.).NOTE:
If the foam seal for the flange is deformed or damaged, it must be replaced.
- Install the foam seal (2) onto the flange.
- Install the A/C expansion valve onto the A/C evaporator. Refer to VALVE, A/C EXPANSION, INSTALLATION .
- Install the evaporator temperature sensor (1) into the driver side of the HVAC housing (2). Make sure the retaining tabs (3) are fully engaged to the housing.
- Position the blower motor (2) into the bottom of the HVAC housing (3).
- Install the three screws (1) that secure the blower motor to the HVAC housing. Tighten the screws to 1.2 N.m (10 in. lbs.).
- Position the blower motor power module (5) into the HVAC housing.
- Install the two screws (4) that secure the blower motor power module to the HVAC housing. Tighten the screws to 1.2 N.m (10 in. lbs.).
- Install the air inlet housing (2) onto the HVAC housing (1). Refer to HOUSING-AIR INLET, INSTALL .
- Install the air distribution housing (3) onto the HVAC housing. Refer to HOUSING-AIR DISTRIBUTION, INSTALL .NOTE:
If the heater core is being replaced, flush the cooling system. Refer to STANDARD PROCEDURE .
- Install the HVAC housing assembly. Refer to HOUSING-HVAC, INSTALL .
