Replacement
Note: LHD type shown, RHD type is similar.
1. Remove the battery.
2. Release the refrigerant.
3. Remove the bolts and disconnect the lines from the evaporator.
Note: Close the line openings immediately after disconnecting to prevent dirt and moisture from entering.
4. Remove the glove box.
5. Remove the self-tapping bolts and the passenger side dash panel lower cover, then remove the 4 bolts and glove box frame.
6. Disconnect the connector from the A/C thermostat and remove the wires from the evaporator. Remove the self-tapping screws, mounting bolts and nuts. Disconnect the condensate drain hose and remove the evaporator
7. Install in the reverse order of removal. Please note the following points.
- If you are installing a new evaporator, add oil to the system (Nippondenso: ND-OIL8, P/N 38899-PR-003 [or P/N-38899-PR7-A01], or Sanden &Hadsys: SP-10, P/N 38899-P13-003 [or P/N 38899-P13-A01].
- Replace the O-rings on all connections and lubricate them with refrigeration oil before connecting.
Note: Make sure to use rings for HFC 134a (R-134a) refrigerant to prevent leaks.
- Apply sealant to the gaskets.
- Check for leaks. Charge the system and check its performance.
Major repairs
Note: LHD type is shown, RHD type is similar.
1. Remove the evaporator cover and take out the A/C filter.
2. Remove the thermostat sensor from the evaporator core.
3. Remove the self-tapping screws and clamps from the evaporator body.
4. Carefully separate the housing, then remove the evaporator.
5. Remove the expansion valve if necessary.
Note: When loosening the expansion valve nuts, hold the valve or evaporator tube with a wrench, otherwise they may be damaged.
6. Assemble in the reverse order of disassembly. Please note the following points.
- Replace the O-rings at each connection. Lubricate them with refrigeration oil (Nippondenso: ND-OIL8, P/N 38899-PR-003 [or P/N-38899-PR7-A01] or Sanden&Hadsys: SP-10, P/N 38899-P13-003 [or P/N 38899-P13-A01] before connection.
Note: Make sure to use HFC-134a (R-134a) refrigerant rings to prevent leaks.
- Install the expansion valve capillary tube directly onto the suction line and wrap with tape.
- Install the thermostat sensor back to its original location.
