GENERAL REPAIR INSTRUCTIONS

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 pre-
vent cable damage or burning due to shortcircuit-
ing.

4. Raise the vehicle with a jack set against the axle or

the frame.

5. Support the vehicle on chassis stands.
6. Handle brake fluid and engine coolant with great

care.
Spilling these liquids on painted surfaces will dam-
age 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, O-rings, oil seals,

lock washers, and self-locking nuts at disassem-
bly.
Normal function of these parts cannot be guaran-
teed 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 com-

pressed air to make certain that they are free of dirt
and obstructions.

14. Lubricate the rotating and sliding faces of all mov-

ing parts with oil or grease before installation.

15. Use the recommended liquid gasket to prevent

leakage.

16. Be sure to tighten bolts and nuts to the specified

torque, using a properly maintained torque wrench.

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 re-

frigerant to the discharged from the Air conditioning
system, be sure to use the ACR4 or equivalent to
recover and recycle Refrigerant-134a, to promote
the movement for the protection of the ozone layer
covering the earth.

19. To assure safety, always slowly release air pres-

sure from the air tanks before disconnecting pipes,
hoses or other parts from any unit under pressure.
