  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Disconnect the negative (-) battery terminal.
  4.  
  5. Recover the refrigerant with a recovery/recycling/charging station.
  6.  
  7. Remove the bolts (A) and the expansion valve (B) from the evaporator core. Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.
  8.  
  9. When the engine is cool, disconnect the inlet and outlet heater hoses from the heater unit. Engine coolant will run out when the hoses are disconnected; drain it into a clean drip pan. Be sure not to let coolant spill on electrical parts or painted surfaces. If any coolant spills, rinse it off immediately.

  24.  
  25. Install in the reverse order of removal, and note these items:

    If you're installing a new evaporator, add refrigerant oil (ND-OIL8). 
     
    Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing them. Be sure to use the right O-rings for R-134a to avoid leakage. 
     
    Immediately after using the oil, replace the cap on the container, and seal it to avoid moisture absorption. 
     
    Do not spill the refrigerant oil on the vehicle; it may damage the paint; if the refrigerant oil contacts the paint, wash it off immediately. 
     
    Apply sealant to the grommets. 
     
    Make sure that there is no air leakage. 
     
    Charge the system and test its performance. 
     
    Do not interchange the inlet and outlet heater hoses and install the hose clamps securely. 
     
    Refill the cooling system with engine coolant.
