  *a Torque Wrench Fulcrum Length
  
  Using SST, install the air fuel ratio sensor to the exhaust manifold.
  
  SST
  
  09224-00011
  
  Torque:
  
  Specified tightening torque
  
  44 N*m { 449 kgf*cm, 32 ft.*lbf }
  
  Note
  
  If the air fuel ratio sensor has been struck or dropped, replace it.
  Tech Tips
  - Calculate the torque wrench reading when changing the fulcrum length of the torque wrench Click here.
  - When using SST (fulcrum length of 30 mm (1.18 in.)) + torque wrench (fulcrum length of 260 mm (10.2 in.)): 39 N*m (398 kgf*cm, 29 ft.*lbf)
2. Connect the air fuel ratio sensor connector.
3. Engage the 3 wire harness clamps.
INSTALL NO. 1 EXHAUST MANIFOLD HEAT INSULATOR
1. Install the No. 1 exhaust manifold heat insulator to the exhaust manifold converter sub-assembly (TWC: Front Catalyst) with the 4 bolts.
  
  Torque:
  
  12 N*m { 122 kgf*cm, 9 ft.*lbf }
INSPECT FOR EXHAUST GAS LEAK

If gas is leaking, tighten the areas necessary to stop the leak. Replace damaged parts as necessary.
