Checking Exhaust System

NBS002RU

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

●

If anything found, repair or replace damage parts.

Removal and Installation

NBS002RV

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 down because the system will be hot
just after engine stops. 

●

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

●

Refer to 

GI-10, "Components"

  for symbol marks in the figure.

REMOVAL

Disconnect each joint and mounting using power tool.

INSTALLATION

Note the following, and install in the reverse order of removal.

●

If exhaust front tube stud bolts were removed, and install them and tighten to the specified torque below.

CAUTION:

●

Always replace exhaust tube gaskets with new ones when reassembling.

●

If heat insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the heat
insulator, remove them.

●

When installing heat insulator avoid large gaps or interference between heat insulator and each
exhaust pipe.

●

Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gases leakage. 

●

Temporarily tighten mounting nuts and bolts on the exhaust manifold side, and mounting bolts
and nuts on the vehicle side. Check each part for unusual interference, and then tighten them to
the specified torque. 

●

When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/
left directions.

INSPECTION AFTER INSTALLATION

●

Make sure that clearance between tail tube and rear bumper is even.

●

With engine running, check exhaust tube joints for gases leakage and unusual noises.

●

Make sure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.

PRECAUTIONS

Revision: 2006 July

2007 Murano

PRECAUTIONS

PFP:00001

Caution

NDS0008P

Observe the following precautions when disassembling and servicing drive shaft.

●

Joint sub-assembly does not disassemble because it is non-overhaul parts.

●

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 service
location.

●

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 kerosene which shall be removed by
blowing with air or wiping with paper shop cloths.
