SERVICE PRECAUTION

WARNING: THIS VEHICLE HAS A SUPPLEMENTAL

RESTRAINT SYSTEM (SRS). REFER TO THE SRS

COMPONENT AND WIRING LOCATION VIEW IN

ORDER TO DETERMINE WHETHER YOU ARE

PERFORMING SERVICE ON OR NEAR THE SRS

COMPONENTS OR THE SRS WIRING. WHEN YOU

ARE PERFORMING SERVICE ON OR NEAR THE

SRS COMPONENTS OR THE SRS WIRING, REFER

TO THE SRS SERVICE INFORMATION. FAILURE TO

FOLLOW WARNINGS COULD RESULT IN

POSSIBLE AIR BAG DEPLOYMENT, PERSONAL

INJURY, OR OTHERWISE UNNEEDED SRS SYSTEM

REPAIRS.

CAUTION: Always use the correct fastener in the

proper location. When you replace a fastener, use

ONLY the exact part number for that application.

HOLDE N will call out those f asten ers th at requir e a

replacement after removal. HOLDEN will also call

out the fasteners that require thread lockers or

thread sealant. UNLESS OTHERWISE SPECIFIED,

do not use supplemental coatings (Paints , greases,

or other corrosion inhibitors ) on threaded fast eners

or fastener joint interfaces. Generally, such

coatings adversely affect the fastener torque and

the joint clamping force, and may damage the

fastener. When you install fasteners, use the

correct tightening sequence and specifications.

Following these instructions can help you avoid

damage to parts and systems.

GENERAL DESCRIPTION

150RX019

When inspecting or replacing exhaust system

components, make sure there is adequate clearance

from all points on the underbody to prevent overheating

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.

Three Way Catalytic Converter

The three way catalytic converter is an emission control

device added to the exhaust system to reduce

pollutants from the exhaust gas stream.

CAUTION: The catalytic converter requires the use

of unleaded fuel only.

Periodic maintenance of the exhaust system is not

required. If the vehicle is raised for other service, it is

advisable to check the condition of the complete

exhaust system.

A dual bed monolith catalytic converter is used in

combination with three way catalytic converter.

Catalytic Converter Types:

Three way (Reduction/Oxidation) catalyst

The catalyst coating on the three way (reduction)

converter contains platinum and rhodium which lowers

the levels of nitrous oxide (NOx) as well as

hydrocarbons (HC) and carbon monoxide (Co).

Gasket

The gasket must be replaced whenever a new exhaust

pipe, muffler or catalyt ic converter is installed.
