Removal

• Disconnect the cable from the negative battery terminal.
• Discharge the refrigerant from the air conditioning system.
• Remove the air filter.
• Remove the glove box.
• Remove the lower panel from the passenger side of the instrument panel.
• Disconnect the suction hose from the evaporator.
• Remove the bolts and disconnect the refrigerant tube from the evaporator. Immediately close all open holes and tubes to prevent moisture from the air from entering the air conditioning system.
• Disconnect the drain hose from the evaporator.
• Disconnect the connector, unscrew the nuts and remove the evaporator.

Disassembly

• Using a screwdriver, lever out the clamps holding the top and bottom sections of the evaporator housing together (Fig. 18.23).

• Remove the compressor control unit.
• Remove the expansion valve.
• Remove the evaporator from the lower section of the evaporator body.

Assembly

• The evaporator is assembled in the reverse order of disassembly, replacing the sealing rings and lubricating them with SUN PAG 56 compressor oil (Fig. 18.24).

Installation

• The evaporator is installed in the reverse order of removal, taking into account the following.
• When replacing the evaporator, pour 60 ml of SUN PAG 56 compressor oil into the air conditioning system.
• Replace the sealing rings and lubricate them with compressor oil (Fig. 18.25).
