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.
ISUZU will call out those fasteners that require a
replacement after removal. ISUZU 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 fasteners
or fasteners 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 specification.
Following these instructions can help you avoid
damage to parts and systems.

GENERAL REPAIR INSTRUCTIONS
1. Park the vehicle on level ground and chock the
front or rear wheels before lifting the vehicle.
2. Use covers on the vehicle body, seats, and
floor to prevent damage and/or
contaminations.
3. Disconnect the grounding cable from the
battery before performing service operations.
This will prevent cable damage or burning due
to shortcircuiting.
4. Raise the vehicle with a jack set against the
recommended lifting points (see ÒLifting
instructionsÓ in this section).
5. Support the vehicle on chassis stands.
6. Handle brake fluid and antifreeze solution with
great care.
Spilling these liquids on painted surfaces will
damage the paint.
7. The use of the proper tool(s) and special tool(s)
where specified is essential to efficient,
reliable, and safe service operations.
8. Always use genuine ISUZU replacement parts.
9. Discard used cotter pins, gasket, plastic clips,
O-rings, oil seals, lock washers, and self-
locking nuts at disassembly.
Normal function of these parts cannot be
guaranteed if they are reused.
10. Keep the disassembled parts neatly in groups.
This will facilitate smooth and correct
reassembly.11. Keep fixing nuts and bolts separate.
Fixing nuts and bolts vary in hardness and
design according to installation positions.
12. Clean all parts before inspection or
reassembly.
13. Clean the oil ports and other openings with
compressed air to make certain that they are
free of dirt and obstructions.
14. Lubricate the rotating and sliding faces of all
moving parts with oil or grease before
installation.
15. Use the recommended liquid gasket to prevent
leakage.
16. Carefully observe all nut and bolt torque
specifications.
17. When service operation is completed, make a
final check to be sure service has been done
properly and problem has been corrected.
18. When removing or replacing parts that require
refrigerant to be discharged from the air
conditioning system, be sure to use the
following tools to recover and recycle the
Refrigerant-134a (R-134a).
For 134a:
Use the R-134a Refrigerant Recovery/Recovery/
Recycling/Recharging/System (ACR
4) or its
equivalent to prevent the discharge of
refrigerant into the air.

RECOMMENDED LIQUID GASKET
* RTV: Room Temperature Vulcanizer
NOTE:
1. It is very important that the liquid gaskets listed above or their exact equivalent be used on the vehicle.
2. Be careful to use the specified amount of liquid gasket.
Follow the manufacturerÕs instructions at all times.
3. Be absolutely sure to remove all lubricants and moisture from the connecting surfaces before applying
the liquid gasket.
The connecting surfaces must be perfectly dry.
4. Do not apply LOCTITE 515 and LOCTITE 518 between two metal surfaces having a clearance of greater
than 0.25 mm (0.01 in). Poor adhesion will result.
RECOMMENDED THREAD LOCKING AGENTS
NOTE:When the application procedures are specified in this manual, follow them.
