Exhaust Pipe -- Installation



1. INSTALL FRONT EXHAUST PIPE ASSEMBLY

  1. Using a vernier caliper, measure the free length of the compression spring.

    Minimum length:
    40 mm (1.57 in.)
    If the free length is less than the minimum, replace the compression spring.
  1. Install the front exhaust pipe to the exhaust pipe support.

    NOTICE:
    1. Be sure to install the gasket so that it faces the correct direction.
    2. Do not reuse the gasket.
    3. Do not damage the gasket.
    4. When connecting the exhaust pipe, do not push in the gasket with the exhaust pipe.
  1. Connect the front exhaust pipe to the exhaust manifold with the 2 compression springs and 2 bolts. Alternately tighten the bolts in several passes.

    Torque:
    43 N*m{438 kgf*cm, 32 ft.*lbf}


2. INSTALL HEATED OXYGEN SENSOR (for Bank 1 Sensor 2)

  1. Using SST, install the heated oxygen sensor.

    SST

    Torque:
    for use without SST:
    44 N*m{449 kgf*cm, 32 ft.*lbf}
    for use with SST:
    40 N*m{408 kgf*cm, 30 ft.*lbf}

    Fulcrum Length
    HINT:
    1. Use a torque wrench with a fulcrum length of 300 mm (11.8 in.). When using a torque wrench with a fulcrum length that is not 300 mm (11.8 in.), calculate the torque specification for the torque wrench and SST based on the "without SST" torque specification (HILUX_TGN26 RM000004QR1003X.html).
    2. Make sure SST and the wrench are connected in a straight line.
  1. Connect the heated oxygen sensor connector.



3. INSTALL AIR FUEL RATIO SENSOR (for Bank 1 Sensor 1)

    2. Make sure SST and the wrench are connected in a straight line.
  1. Attach the 3 wire harness clamps to the vehicle body.

  1. Connect the air fuel ratio sensor connector.



4. INSTALL CENTER EXHAUST PIPE ASSEMBLY
  1. Install the center exhaust pipe to the 3 exhaust pipe supports.

  1. Install a new gasket and the center exhaust pipe to the front exhaust pipe with the 2 bolts and 2 nuts. Alternately tighten the bolts in several passes.

    Torque:
    48 N*m{489 kgf*cm, 35 ft.*lbf}
    NOTICE:
    Do not reuse the gasket.


5. INSTALL TAILPIPE ASSEMBLY
  1. Install the tailpipe to the exhaust pipe support.

  1. Install a new gasket and the tailpipe to the center exhaust pipe with the 2 bolts and 2 nuts. Alternately tighten the bolts in several passes.

    Torque:
    48 N*m{489 kgf*cm, 35 ft.*lbf}
    NOTICE:
    Do not reuse the gasket.


6. INSPECT FOR EXHAUST GAS LEAK
If gas is leaking, tighten the areas necessary to stop the leak. Replace damaged parts as necessary.
