Removal and Installation

INFOID:0000000007358896

WARNING:

• Perform the operation with the exhaust system fully cooled. The system will be hot just after the

engine stops.

• Be careful not to cut your hand on the heat insulator edge.

CAUTION:

• Be sure to use genuine exhaust system parts or equivalents which are specially designed for heat

resistance, corrosion resistance, and shape.

REMOVAL

Remove exhaust system components using power tool.

• Remove heated oxygen sensor using Tool as needed.

INSTALLATION

Installation is in the reverse order of removal.

CAUTION:

• Always replace exhaust gaskets with new ones when reassembling.

• Before installing a new heated oxygen sensor, clean and lube the exhaust tube threads using suit-

able tool.

< REMOVAL AND INSTALLATION >

EXHAUST SYSTEM

• Discard any heated oxygen sensor which has been dropped from a height of more than 0.5 m (19.7

in) onto a hard surface such as a concrete floor; install a new one.

• Do not over-tighten the heated oxygen sensor. Doing so may damage the heated oxygen sensor,

resulting in the MIL coming on.

• If any mounting insulator is badly deformed, repair or replace it. If deposits such as mud pile up on

the mounting insulators, clean and inspect them.

• Temporarily tighten the nuts on the exhaust manifold side and the bolts on the vehicle side. Check

each part for interference with other components, and then tighten the nuts and bolts to specifica-

tion.

INSPECTION AFTER INSTALLATION

• With the engine running, check exhaust tube joints for exhaust gas leaks and unusual noises.

• Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue

stress. Improper installation could result in excessive noise and vibration.
