Installation [06/2020 - 10/2022]: Procedure

  1. INSTALL COOLER UNIT DRAIN HOSE GROMMET 
    NOTE:

    Perform this procedure only when removal/installation of the cooler unit drain hose grommet is necessary. 

    After removing the cooler unit drain hose grommet, replace it with a new one to prevent water from entering.

    1. Attach one side of the lip on a new cooler unit drain hose grommet (approximately 1/3 of the circumference) to the body hole (fit it to the hole).

      *a Lip Penetrate Area
    2. Press the entire upper surface of the rib on the cooler unit drain hose grommet, and fit the entire circumference of the lip to the hole.
      NOTE:
      • If the lip on the cooler unit drain hose grommet is not completely fit to the hole, water or noise may enter the interior. When fitting the lip to the hole, make sure that there are no gaps between the lip and body.
      • Do not allow any foreign matter to be trapped between the cooler unit drain hose grommet and installation area, as this may allow noise to enter.
      • Removing the cooler unit drain hose grommet after it has been installed damages the lip due to burrs on the body punch hole (vehicle exterior). This may reduce contact between the edge of the lip and body and cause water to enter the interior. Therefore, do not reuse the cooler unit drain hose grommet.
      • When installing the cooler unit drain hose grommet, do not leave the lip only partially fit to the hole (as in the previous step). This may reduce contact due to lip deformation and cause water to enter the interior. Once you have started to install the part, complete the installation without stopping.

  2. INSTALL ID CODE BOX (IMMOBILIZER CODE ECU) 

    Refer to PROCEDURE - Step 1

  3. INSTALL NO. 1 AIR DUCT SUB-ASSEMBLY 

    HINT: 

    Perform this procedure only when removal/installation of the No. 1 air duct sub-assembly is necessary.

    1. Install the No. 1 air duct sub-assembly with the 2 nuts in the order shown in the illustration.

      Torque: 9.8 N*m (100 kgf*cm, 87 in.*lbf) 

      NOTE:
      • Make sure there are no cracks in the No. 1 air duct sub-assembly.
      • Make sure no foreign matter, such as the dash panel insulator, is trapped between the cowl and seal packing.
      • Make sure that the seal packing is securely attached to the cowl on the body. Look from the engine compartment and check that it does not drop down into the fresh air vent. (If foreign matter, such as the dash panel insulator, is trapped or if the seal packing is not securely attached, water or air from gaps may enter the interior.)
  4. INSTALL AIR CONDITIONING UNIT ASSEMBLY 
    NOTE:
    • Be sure to support the air conditioning unit assembly when installing it because failure to do so may cause the bracket of the air conditioning unit assembly to break.
    • When installing the air conditioning unit assembly, eliminate static electricity by touching the vehicle body to prevent the components from being damaged.
    • Be careful not to damage the internal components of the instrument panel reinforcement assembly and air conditioning unit assembly on the glass etc. Only perform installation after first taking the appropriate actions.
    • Do not allow the air conditioning unit assembly to strike the airbag sensor assembly. Doing so may damage the heater case, causing water leaks.
    1. Temporarily set the air conditioning unit assembly nearby the position where it is to be installed.
      NOTE:

      When carrying the air conditioning unit assembly, hold the bottom of the assembly. Do not hold the following parts. 

      • Do not hold the air conditioning harness assembly. Otherwise, static electricity from the technician may damage the air conditioning harness assembly.
      • Do not hold the heater core or pipe of the heater radiator unit sub-assembly. Otherwise, the pipe may detach, the clamp may be damaged, or the crimped areas of the heater core and pipe of the heater radiator unit sub-assembly may be damaged, causing coolant to leak.
      • Do not hold the air conditioning radiator damper servo sub-assembly, blower damper servo sub-assembly or link. Otherwise, the servo motor may become misaligned, causing abnormal operation noise, temperature control defects, or air leaks due to sealing defects in the doors.
      • Do not hold the door. Doing so may cause air leaks due to closing defects resulting from excessive opening/closing. Also, keep the door free from oil and grease.
    2. Temporarily install the air conditioning unit assembly to the instrument panel reinforcement assembly with the 3 bolts.

  7. INSTALL INSTRUMENT PANEL REINFORCEMENT ASSEMBLY WITH AIR CONDITIONING UNIT ASSEMBLY 
    NOTE:
    • Be sure to support the air conditioning unit assembly when installing it because failure to do so may cause the bracket of the air conditioning unit assembly to break.
    • When installing the air conditioning unit assembly, eliminate static electricity by touching the vehicle body to prevent the components from being damaged.
    • Be careful not to damage the internal components of the instrument panel reinforcement assembly with air conditioning unit assembly on the glass etc. Only perform installation after first taking the appropriate actions.
    1. Install the instrument panel reinforcement assembly with air conditioning unit assembly to the guide as shown in the illustration.
      NOTE:

      When carrying the instrument panel reinforcement assembly with air conditioning unit assembly, hold the bottom of the assembly. Do not hold the following parts. 

      • Do not hold the air conditioning harness assembly. Otherwise, static electricity from the technician may damage the air conditioning harness assembly.
      • Do not hold the heater core or pipe of the heater radiator unit sub-assembly. Otherwise, the pipe may detach, the clamp may be damaged, or the crimped areas of the heater core and pipe of the heater radiator unit sub-assembly may be damaged, causing coolant to leak.
      • Do not hold the air conditioning radiator damper servo sub-assembly, blower damper servo sub-assembly or link. Otherwise, the servo motor may become misaligned, causing abnormal operation noise, temperature control defects, or air leaks due to sealing defects in the doors.
      • Do not hold the door. Doing so may cause air leaks due to closing defects resulting from excessive opening/closing. Also, keep the door free from oil and grease.
      NOTE:
      • Do not allow the heater radiator unit sub-assembly heater pipe or connector tube to strike the body.
