Exhaust System – V6 Page 6F – 3


The Catalytic converter can be damaged or
rendered ineffective, if:
• operated outside the limits of the closed
loop mixture control system
• the engine burns excessive amount of oil
• the exhaust temperature at the converter
is too high (exceeds 840°C).
The catalytic material is very sensitive to the effects of a rich or lean fuel mixture, which may cause the temperature of
the converter to rise rapidly. The catalytic converter normally operates at approximately 600 °C.
The catalytic converter is also sensitive to the use of leaded petrol. Using leaded fuel can cause deposits to form in the
converter, which restrict exhaust flow and prevent the catalyst from working. This will result in an increase in exhaust
backpressure and converter temperature.
NOTE
The use of unleaded petrol results in black
tailpipe deposits rather than the grey colour that
some people may normally associate with an
acceptable combustion condition. This black
colour resulting from the use of unleaded fuel
does not necessarily indicate a state of poor
engine tune. For V6 engines, Refer to: 6C1 – 1
Engine Management General Information.
Euro 3 Emissions Standards
The Euro 3 emissions standard is a European standard which aims at setting vehicle emissions targets to encourage
vehicle manufacturers to reduce harmful vehicle emissions such as Carbon Monoxide (CO), Hydrocarbons (HC) and the
various oxides of Nitrogen (NOx).

This vehicle is fitted with a supplemental
restraint system (SRS). Refer to section 9A
Restraints, in order to determine whether you
are performing service on or near the SRS
components or the SRS wiring.

Always use the correct fastener in the proper
location. When you replace a fastener, use
ONLY the exact part number for that
application. Isuzu will identify those fasteners
that require a replacement after removal and
fasteners that require thread lockers or thread
sealant. Unless otherwise specified, do not
use supplemental coatings (Paints, greases
or corrosion inhibitors) on thread fasteners or
fastener joints. Generally such coatings
adversely effect the fastener torque and the
joint clamping force, and may damage the
fastener. When you install fasteners, use the
correct tightening sequence and torque
specifications.

Service Notes
1. Vehicles fitted with catalytic converters should not be operated with leaded petrol. Lead will contaminate
the ceramic monolith.
2. Do not drop the catalytic converter as it will damage the ceramic monolith.
3. Replace the catalytic converter if it is damaged.
4. Do not allow water, oil or fuel to enter the converter as the ceramic monolith will be contaminated.
5. Do not use engine and/or fuel additives unless approved by General Motors. Many additives contain phosphorous that will contaminate the ceramic monolith.
6. The vehicle must not be started by pushing or towing, as unburned fuel could reach the catalytic converter and destroy the ceramic monolith. Always use jumper leads to start a vehicle that has a flat or
defective battery.
7. W hen carrying out a compression test, for V6 engines use Tech 2 to ensure the output control Engine Compression Test is set to enable, refer to 6A1 Engine Mechanical. This prevents fuel injection and
ignition during engine cranking.
8. Do not drive the vehicle with the engine misfiring or with any of the spark plug leads disconnected, as the catalytic converter will overheat.
9. Do not coast downhill with the engine misfiring or with any of the spark plug leads disconnected.
10. The catalytic converter is serviceable as part of the front exhaust assembly only. Refer to the service operations in this section for details of front exhaust pipe assembly removal and reinstallation.
11. The exhaust flange gaskets must be replaced whenever a new exhaust pipe, muffler or catalytic converter is installed.
1.3 WARNING, CAUTION and NOTES
This Section contains various W ARNINGS, CAUTIONS and NOTE statements that you must observe carefully to reduce
the risk of death or injury during service, repair procedures or vehicle operation. Incorrect service or repair procedures
may damage the vehicle or cause operational faults. W ARNINGS, CAUTION and NOTE statements are not exhaustive.
HOLDEN LTD can not possibly warn of all the potentially hazardous consequences of failure to follow these instructions.
1.1 Definition of WARNING, CAUTION and NOTE Statements

Diagnosis and repair procedures in this Section contain both general and specific W ARNING, CAUTION and NOTE
statements. HOLDEN LTD is dedicated to the presentation of service information that helps the technician to diagnose
and repair the systems necessary for proper operation of the vehicle. Certain procedures may present a hazard to the
technician if they are not followed in the recommended manner. W ARNING, CAUTION and NOTE statements are
designed to help prevent these hazards from occurring, but not all hazards can be foreseen.
WARNING defined
A W ARNING statement immediately precedes an operating procedure or maintenance practice which, if not correctly
followed, could result in death or injury. A W ARNING statement alerts you to take necessary action or not to take a
prohibited action. If a W ARNING statement is ignored, the following consequences may occur:
• Death or injury to the technician or other personnel working on the vehicle,
• Death or injury to other people in or near the workplace area, and / or
• Death or injury to the driver / or passenger(s) of the vehicle or other people, if the vehicle has been improperly
repaired.
CAUTION defined
A CAUTION statement immediately precedes an operating procedure or maintenance practice which, if not correctly
followed, could result in damage to or destruction of equipment, or corruption of data. If a CAUTION statement is
ignored, the following consequences may occur:
• Damage to the vehicle,
• Unnecessary vehicle repairs or component replacement,

This guide includes such information as:
• Transmission Cutaway Views,
• Principles of Operation,
• Power Flow,
• Complete Hydraulic Circuits,
• Bushing and Bearing Locations,
• Seal Locations and
• Illustrated Parts List.
NOTE
Specifications quoted in this General Motors
Powertrain Group Electronically Controlled
Automatic Transmission Technician Guide may
not be for the vehicle you are working on. For
correct specifications refer to
7 Transmission Specifications.
Recommendations
When servicing the transmission, all parts should be cleaned and inspected. Individual units should be reassembled
before disassembly of other units to avoid confusion and interchanging of parts.
a Thoroughly clean the transmission exterior before removal of any component.
b Disassembly and reassembly must be made on a clean work bench. Cleanliness is of the utmost importance, the bench tools and parts must be kept clean at all times.
c Before installing screws and other fasteners into aluminium parts, dip screw threads into transmission fluid to prevent galling aluminium threads and to prevent screws from seizing.
d To prevent thread stripping, always use a torque wrench when installing screws or nuts.
e If threads in aluminium parts are stripped or damaged, the parts can be made serviceable by the use of commercially available thread inserts.
f Protective tools must be used when assembling seals to prevent damage. The slightest flaw in the sealing surface of the seal can cause an oil leak.
g Aluminium castings and valve parts are very susceptible to nicks, burrs, etc. and should be handled with care.
h Expand Internal snap rings and compress external snap rings if they are to be re-used to ensure proper seating when reinstalled.
i Do not re-use removed O-rings, gaskets and oil seals.
j Teflon oil seal rings should not be removed unless damaged.
k During assembly of each unit, all internal moving parts must be lubricated with transmission fluid.
Oil Cooler Pipes
Should any transmission fluid cooling pipe suffer accidental damage, a genuine replacement pipe must be fitted. Refer to
the current release of PartFinder™ to determine the correct part number for the particular engine and pipe involved.
Reworking of damaged pipes or hand made replacements are not permitted.
