Refrigerant Line Repair Procedures

Replacement

1. 1
   If the compressor is locked up, run the engine at idle and let the air conditioner operate for a few minutes, then stop the engine.
2. 2
   Disconnect the negative (-) battery terminal.
3. 3
   Recover the refrigerant using a recovery/recharging station.
4. 4
   Remove the engine cover (A).

   

5. 5
   Remove the expansion valve cap (A) after loosening the nut.

   Tightening torque: 8.8 ~ 11.8 N·m

   

6. 6
   Remove the bolts and the expansion valve (A) from the evaporator core.

   Tightening torque: 8.8 ~ 11.8 N·m

   

7. 7
   Loosen the mounting bolt of the bracket (B) on the suction and liquid line assembly (A).

   Tightening torque: 8.8 ~ 11.8 N·m

   

8. 8
   Disconnect the air conditioner pressure sensor connector (A).

   

9. 9
   Remove the 2 nuts, then disconnect the discharge line (A) and liquid line (B) from the condenser.

   Tightening torque: 8.8 ~ 11.8 N·m

   

10. 10
    Remove the engine room cover. (Refer to Engine Mechanical System - Engine Room Under Cover)
11. 11
    Remove the bolts, then disconnect the suction line (A) and discharge line (B) from the compressor.

    Tightening torque: 8.8 ~ 11.8 N·m

    Plug or cover the lines immediately after disconnecting them to prevent moisture and dust from entering.

    

12. 12
    Install in the reverse order of removal.

    Plug or cover the lines immediately after disconnecting them to prevent moisture and dust from entering. Tighten the bolt or nut to the specified torque. Check for refrigerant leaks using a gas leak detector. Evacuate the air conditioning system and charge it with refrigerant.
