      7.0 N*m  { 71 kgf*cm, 62 in.*lbf }

    2. Attach the wire harness clamp to the air cleaner case.

  6. INSTALL AIR CLEANER CASE SUB-ASSEMBLY (for 2ZR-FAE)


    1. A01IQF0

      Install the air cleaner case with the 3 bolts.

      Torque:
      7.0 N*m  { 71 kgf*cm, 62 in.*lbf }

    2. Attach the wire harness clamp to the air cleaner case.

  7. INSTALL AIR CLEANER CAP SUB-ASSEMBLY (for 1ZR-FAE)


    1. A01IPUC

      Connect the air cleaner cap with the band.

    2. Connect the PCV hose.

    3. A01IP4V

      Connect the 2 clamps.

    4. A01ISEG

      Attach the 2 clamps and connect the wire harness.

    5. Connect the mass air flow meter connector.

  8. INSTALL AIR CLEANER CAP SUB-ASSEMBLY (for 2ZR-FAE)


    1. A01IPUC

      Connect the air cleaner cap with the band.

    2. Connect the PCV hose.

    3. A01IP4V

      Connect the 2 clamps.

    4. A01ISEG

      Attach the 2 clamps and connect the wire harness.

    5. Connect the mass air flow meter connector.

  9. INSTALL NO. 2 CYLINDER HEAD COVER (for 1ZR-FAE)


    1. A01IRS7

      Attach the 4 clips to install the cover.

      Note


      • Be sure to attach the clips securely.

      • Do not apply excessive force or hit the cover to attach the clips. This may cause the cover to break.

  10. INSTALL NO. 2 CYLINDER HEAD COVER (for 2ZR-FAE)


    1. A01IRS7

      Attach the 4 clips to install the cover.

      Note


      • Be sure to attach the clips securely.

      • Do not apply excessive force or hit the cover to attach the clips. This may cause the cover to break.

  11. INSPECT VACUUM PUMP OPERATION


    1. Slide the clip and disconnect the union to connector tube hose from the vacuum pump.

    2. A01IUQ8

      Connect the hose of a vacuum gauge to the vacuum pump.

    3. Start the engine and warm it up for more than 2 minutes.

    4. With the engine idling, measure the vacuum of the vacuum pump.

      Standard pressure
      Higher than 87 kPa (650 mmHg, 25.6 in.Hg)

      Tech Tips

      It is necessary to replace the vacuum pump assembly every 200000 km (124000 miles).

    5. Remove the vacuum gauge from the vacuum pump.

    6. Connect the union to connector tube hose to the vacuum pump with the clip.
