NSX Models

CAUTION
Before starting service procedures on components, especially under the instrument panel and/or near the steering column, disable the SRS system. In addition, the vehicle may be equipped with a radio anti-theft code (5 digits). Get this code from the customer before disconnecting the battery.

  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2.  
  3. If equipped with SRS or an anti-theft radio, perform the following procedures:
    WARNING
    Do not use electrically powered test equipment on this system or related circuits. All SRS wiring is covered with a special yellow cable housing for identification.


    CAUTION
    All SRS wiring harnesses are covered with yellow outer insulation. Before disconnecting any part of the SRS wire harness, install short connection to prevent accidental discharge of the air bag system. If the SRS harness assembly should have an open circuit or damaged wiring, replace the entire affected harness.



    Disconnect the negative battery cable, then disconnect the positive battery cable.
     
    Remove the access panel beneath the air bag on the under-side of the steering wheel center housing.
     
    Disconnect the connector between the air bag and the cable reel and install the short connector (red) that is provided. Install this connector on the air bag side of the connector.
     
    The system is now disabled. When repairs are complete, unplug the red short connector, reconnect the air bag and cable reel connector and replace the access panel.
     
    Reconnect the battery. When the word CODE appears, re-enter the 5-digit code in the radio, if equipped.
     
    When the ignition is turned to the II position, the SRS light on the instrument cluster should come ON for about 6 seconds, then go out. If so, the system is okay.
     

  4.  
  5. Disconnect the negative battery cable.
  6.  
  7. Properly drain the cooling system. Properly discharge the air conditioning system using an approved refrigerant recover/recycling system.
  8.  
  9. Remove or disconnect the following:

    Blower assembly
     
    Refrigerant lines from their connection at the firewall. Cap all opening immediately to keep dirt and moisture from contaminating the system.
     

  10.  
  11. Remove the dashboard by removing or disconnecting the following:

    Front seats
     
    Knee bolster, pad, dashboard stay and center armrest
     
    Clock, center air vent and center console panel
     
    Heater/air conditioning control panel and the radio assembly
     
    Right dashboard lower panel. Remove the glove box
     
    Lower the steering column
     
    Instrument cluster bezel and the instrument cluster
     
    Air vents from both ends of the dashboard

  16.  

To install:

  1. Installation is the reverse of the removal procedures.
  2.  
  3. Add 0.3 oz. of extra refrigerant oil if the evaporator core was replaced.
  4.  
  5. Adjust the heater valve cable, if needed.
  6.  
  7. Refill the cooling system and bleed the system by performing the following procedure:
    WARNING
    Failure to properly bleed the air from the cooling system could cause engine damage.

  8.  
  9. Turn the ignition switch ON and slowly set the climate control temperature knob to 90 . This will allow the coolant in the heater to drain out with the rest of the system.
  10.  
  11. Open the hood, rear hatch and the engine cover.
  12.  
  13. Remove the cover protecting the water pipes and shift cables on the underside of the car.
  14.  
  15. Carefully loosen the coolant reserve tank cap. Loosen the drain plug at the bottom of the radiator. Remove the 2 drain bolts from the water pipes. Install rubber hoses to the drain bolts at the front and rear of the engine under the cylinder bank and loosen the drain bolts to drain the coolant.
  16.  
  17. Coolant will drain more quickly if all the air bleed bolts, plug and cap are opened. Be sure the coolant reserve tank has drained completely before opening the air bleed bolts.
  18.  
  19. Using new washers on the water pipe drain bolts, install the drain bolts and radiator drain plug.
  20.  
  21. Open all 4 air bleeder bolts (radiator, heater pipe, water pipe and engine thermostat cover).
  22.  
  23. Using approved coolant in a 50/50 mixture, fill the coolant reserve tank. Tighten the bleeders in sequence; thermostat cover bleed bolt, radiator bleed plug, heater pipe bleed cap, and water pipe bleed bolt as coolant runs out in a steady stream with no bubbles.
  24.  
  25. After tightening all the bleed bolts, fill the coolant tank to the MAX line. Loosen the thermostat bleed bolt to remove any remaining air.
  26.  
  27. When bleeding is complete, tighten the thermostat bolt and fill the coolant reserve tank to the MAX line again. Install the tank cap to the 1st detent.
  28.  
  29. Start the engine and run it to normal operating temperatures (thermostat opens and radiator cooling fan runs).
  30.  
  31. Turn the engine OFF , check and adjust the coolant to the MAX line if needed.
  32.  
  33. Install the coolant tank cap securely and install the car-s undercover.
  34.  
  35. Evacuate, charge and leak test the air conditioning system.
  36.  
  37. Connect the negative battery cable.
  38.
