0A-2 GENERAL INFORMATION
GENERAL REPAIR INSTRUCTIONS
1. Park the vehicle on level ground and chock the front or rear wheels before lifting the vehicle.
2. Raise the vehicle with a jack set against the axle or the frame.
3. Support the vehicle on chassis stands.
4. Use covers on the vehicle body, seats, and floor to prevent damage and/or contamination.
5. Disconnect the grounding cable from the battery before performing service operations.

This will prevent cable damage or burning due to short circuiting.
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, gaskets, 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. Prepare new cotter pins, gaskets, O-rings, oil seals, lock washers, and self-locking nuts for installation.
11. Keep the disassembled parts neatly in groups.
This will facilitate smooth and correct reassembly.
12. Keep fixing nuts and bolts separate.
Fixing nuts and bolts vary in hardness and design according to installation position.
13. Clean all parts before inspection or reassembly.
14. Clean the oil ports and other openings with compressed air to make certain that they are free from dirt and
obstructions.
15. Lubricate the rotating and sliding faces of all moving parts with oil or grease before installation.
16. Use the recommended liquid gasket to prevent leakage.
17. Carefully observe all nut and bolt torque specifications.
18. When removing or replacing parts that require refrigerant to the discharged from the Air conditioning system, be
sure to use the Vehicle Refrigerant Recovery and Recycling Equipment (VRRRE) to recover and recycle R134a,
to promote the movement for the protection of the ozone layer covering the earth.
19. Check and recheck your work. No service operation is complete until you have done this.

GENERAL INFORMATION 0A-5

7. Measurement criteria are defined by the terms "standard" and "limit".

A measurement falling within the "standard" range indicates that the applicable part or parts are serviceable.
"Limit" is an absolute value.

A measurement falling outside the "limit" indicates that the applicable part or parts must be repaired or replaced.
8. Components are parts are listed in the singular form throughout the Workshop Manual.
9. The following directional criteria are used throughout the Workshop Manual:

Front:

The cooling fan side of the engine.
Right:

The right-hand side of the engine viewed from the flywheel.

Left:
The left-hand side of the engine viewed from the flywheel.

Rear:

The flywheel side of the engine.
Cylinder numbers are counted from the front of the engine towards the rear.

The engine's rotation is clockwise viewed from the front of the engine.

REPAIR OF REFRIGERANT LEAKS
Refrigerant Line Connections


RTW410SH000101
Install new O-ring, if required. When disconnecting or
connecting lines, use two wrenches to prevent the connecting
portion from twisting or becoming damaged.


When connecting the refrigerant line at the block joint, securely
insert the projecting portion of the joint portion into the
connecting hole on the unit side and secure with a bolt.




Apply specified compressor oil to the O-rings prior to
connecting.

CAUTION:
Compressor (PAG) oil to be used varies according to
compressor model. Be sure to apply oil specified for the
model of compressor.



O-rings must be closely aligned with raised portion of
refrigerant line.

Direct charging with a manifold gauge charging
station method.
Handling the charging valve handle when installing refrigerant
container.
1) Before attaching the charge valve to the refrigerant
container, turn the charge valve handle counterclockwise
until the needle is fully retracted.
2) Turn the plate nut counterclockwise until it reaches its
highest position relative to the charge valve.
3) Install the charge valve onto the refrigerant container.
4) Turn the plate nut clockwise and connect the center hose of
the manifold gauge to the charge valve.
5) Tighten the plate nut sufficiently by hand. Then turn the
charge valve handle clockwise to lower the needle and bore
a hole in the refrigerant container.
6) Turn the charge valve handle counterclockwise to raise the
needle. The refrigerant in the refrigerant container is
charged into the air conditioning system by the operation of
the manifold gauge.





Be absolutely sure not to reuse the emptied

HEATER AND AIR CONDITIONING 1-33
refrigerant container.


1) Make sure the evacuation process is correctly completed.
2) Connect the center-hose of the manifold gauge to the
refrigerant container.






Turn the charge valve handle counterclockwise to purge
to the charging line and purge any air exiting in the
center-hose of the manifold gauge.
3) Open the low-pressure hand valve and charge the
refrigerant about 200 g (0.44 lbs.).






Make sure the high-pressure hand valve is closed.






Avoid charging the refrigerant by turning the refrigerant
container upside down.
4) Close the low-pressure hand valve of the manifold gauge.






Check to ensure that the degree of pressure does not
change.
5) Check the refrigerant leaks by using a HFC-134a leak
detector.






If a leak occurs, repair the leak connection, and start all
over again from the first step of evacuation.
6) If no leaks are found, open the low-pressure hand valve of
the manifold gauge. Then continue charging refrigerant to
the system.






When charging the system becomes difficult:
(1) Run the engine at Idling and close the all vehicle
doors.
(2) A/C switch is "ON".
(3) Set the fan control knob (fan switch) to its highest
position.
(4) Set air soure selector lever to “RECIRC”



WARNING
BE ABSOLUTELY SURE NOT TO OPEN THE HIGH-
PRESSURE HAND VALVE. SHOULD THE HIGH-
PRESSURE HAND VALVE BE OPENED, THE HIGH-
PRESSURE REFRIGERANT GAS WOULD FLOW
BACKWARD, AND THIS MAY CAUSE THE REFRIGERANT
CONTAINER TO BURST.
7) When the refrigerant container is emptied, use the following
procedure to replace it with a new refrigerant container.
(1) Close the low-pressure hand valve.
(2) Raise the needle upward and remove the charge valve.
(3) Reinstall the charge valve to the new refrigerant
container.
(4) Purge any air existing in the center hose of the manifold
gauge.
8) Charge the system to the specified amount and then close
the low-pressure hand valve.
