Checking Exhaust System

EBS00QUJ

Check exhaust pipes, muffler and mounting for improper attachment, leaks, cracks, damage or deterioration.

●

If anything is found, repair or replace damaged parts.

Removal and Installation

EBS00QUK

Exhaust System

CAUTION:

●

Be sure to use genuine exhaust system parts or equivalents which are specially designed for heat
resistance, corrosion resistance, and shape.

●

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.

REMOVAL

Remove exhaust system components using power tool.

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 tool.

●

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-torque 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 mounting nuts on the exhaust manifold side and the mounting bolts on the
vehicle side. Check each part for interference with other components, and then tighten the nuts
and bolts to specification. 

INSPECTION AFTER INSTALLATION

●

With the engine running, check exhaust tube joints for gas leakage 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.

PRECAUTIONS

PFP:00001

Precautions

EDS003A7

Observe the following precautions when disassembling and servicing the wheel hub and drive shafts.

●

Perform work in a location which is as dust-free as possible.

●

Before disassembling and servicing, clean the outside of parts.

●

Prevention of the entry of foreign objects must be taken into account during disassembly of the compo-
nent parts.

●

Disassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean
cover must be placed over parts.

●

Paper shop cloths must be used. Fabric shop cloths must not be used because of the danger of lint adher-
ing to parts.

●

Disassembled parts (except for rubber parts) should be cleaned with a suitable solvent which shall be
removed by blowing with air or wiping with paper shop cloths.
