INSTALLATION

1. INSTALL HEATED OXYGEN SENSOR (for Bank 2)
(a) Install the heated oxygen sensor to the exhaust pipe front.
Torque: 44 Nm (450 kgf-cm, 33 ft-lbf)
(b) Connect the heated oxygen sensor connector.

HINT: After installing heated oxygen sensor, check that sensor wire is not twisted. If it is twisted, remove the heated oxygen sensor and reinstall it.

2. INSTALL EXHAUST PIPE ASSEMBLY FRONT
(a) Install a new gasket and the front pipe to the exhaust manifold.
(b) Install the exhaust pipe front with 2 nuts.
Torque: 62 Nm (630 kgf-cm, 46 ft-lbf)
3. INSTALL HEATED OXYGEN SENSOR (for Bank 1)
(a) Install the heated oxygen sensor to the exhaust pipe front.
Torque: 44 Nm (450 kgf-cm, 33 ft-lbf)
(b) Connect the heated oxygen sensor connector.

HINT: After installing heated oxygen sensor, check that sensor wire is not twisted. If it is twisted, remove the heated oxygen sensor and reinstall it.

4. INSTALL NO. 2 EXHAUST FRONT PIPE ASSEMBLY
(a) Install 2 new gaskets and the front pipe to the exhaust manifold.
