GENERAL DESCRIPTION

150RW070

When inspecting or replacing exhaust system
components, make sure there is adequate clearance
from all points on the underbody to prevent overheating
of the floor pan and possible damage to the passenger
compartment insulation and trim materials.
Check complete exhaust system and nearby body
areas and rear compartment lid for broken, damaged,
missing or mispositioned parts, open seams, holes
loose connections or other deterioration which could
permit exhaust fumes to seep into the rear
compartment or passenger compartment. Dust or water
in the rear compartment may be an indication of a
problem in one of these areas. Any faulty areas should
be corrected immediately.

HANGERS

Various types of hangers are used to support exhaust
system(s). These include conventional rubber straps,
rubber rings, and rubber blocks.
The installation of exhaust system supports is very
important, as improperly installed supports can cause
annoying vibrations which can be difficult to diagnose.

GASKET

The gasket must be replaced whenever a new exhaust
pipe, muffler or exhaust throttle is installed.

ON-VEHICLE SERVICE

FRONT EXHAUST PIPE

Rattles and noise vibrations in the exhaust system are
usually caused by misalignment of parts. When aligning
the system, leave all bolts or nuts loose until all parts
are properly aligned; then tighten, working from front to
rear.

1. Check connections for looseness or damage,

especially for exhaust gas leakage.

2. Check clamps and rubbers for weakness, cracks or

damage.

3. If any part of the converter heat shield is damaged

or dented to the extent that it contacts the catalyst,
repair or replace.

4. Check for dents or damage and for any holes or

cracks caused by corrosion.
