General Repair Instruction
1. If a floor jack is used, the following precautions are
recommended.
Park vehicle on level ground, ªblockº front or rear
wheels, set jack against the recommended lifting
points (see ªLifting Instructionsº in this section), raise
vehicle and support with chassis stands and then
perform the service operations.
2. Before performing service operations, disconnect
ground cable from the battery to reduce the chance of
cable damage and burning due to short circuiting.
3. Use a cover on body, seats and floor to protect them
against damage and contamination.
4. Brake fluid and anti±freeze solution must be handled
with reasonable care, as they can cause paint
damage.
5. The use of proper tools and recommended essential
and available tools, where specified, is important for
efficient and reliable performance of service repairs.
6. Use genuine Isuzu parts.
7. Used cotter pins, plastic clips, gaskets, O±rings, oil
seals, lock washers and self±locking nuts should be
discarded and new ones should be installed, as
normal function of the parts cannot be maintained if
these parts are reused.
8. To facilitate proper and smooth reassembly
operation, keep disassembled parts neatly in groups.
Keeping fixing bolts and nuts separate is very
important, as they vary in hardness and design
depending on position of installation.
9. Clean the parts before inspection or reassembly. Also
clean oil ports, etc. using compressed air, and make
certain they are free from restrictions.
10. Lubricate rotating and sliding faces of the parts with
oil or grease before installation.
11. When necessary, use a sealer on gaskets to prevent
leakage.
12. Carefully observe all specifications for bolt and nut
torques.13. When removing or replacing parts that require
refrigerant to be discharged from the air conditioning
system, be sure to use the Vehicle Refrigerant
Recovery and Recycling Equipment (VRRRE) to
recover and recycle Refrigerant±134a.
14. When a service operation is completed, make a final
check to be sure the service has been done properly
and the problem has been corrected.
15. SUPPLEMENTAL RESTRAINT SYSTEM
The vehicle is equipped with a Supplemental
Restraint System (SRS) ± Air Bags. This system is
not to be serviced without consulting the appropriate
service information. Consult Section 9J ªSRS
Systemº if work is to be done on the front of the
vehicle such as bumper, sheet metal, seats, wiring,
steering wheel or column. Also review SRS system
information if any arc welding is to be done on the
vehicle. The SRS system equipped vehicle can be
identified by:
1. ªAIR BAGº warning light on the instrument
cluster.
2. A Code ªKº or ªMº for fifth digit of Vehicle
Identification Number.

0B±6MAINTENANCE AND LUBRICATION
Always change the oil and the oil filter as soon as possible
after driving in a dust storm.
Engine Cooling System Inspection
Inspect the coolant/anti±freeze. If the coolant is dirty or
rusty, drain, flush and refill with new coolant. Keep coolant
at the proper mixture for proper freeze protection,
corrosion inhibitor level and best engine operating
temperature. Inspect hoses and replace if cracked,
swollen or deteriorated. Tighten the hose clamps if
equipped with screw±type clamps. Clean outside of
radiator and air conditioning condenser. Wash filler cap
and neck. To help ensure proper operation, a pressure
test of both the cooling system and the cap is also
recommended.
Exhaust System Inspection
Visually inspect the exhaust pipes, muffler, heat shields
and hangers for cracks, deterioration, or damage.
Be alert to any changes in the sound of the exhaust
system or any smell of fumes. These are signs the system
may be leaking or overheating. Repair the system at
once, if these conditions exist. (See also ªEngine Exhaust
Gas Safetyº and ªThree Way Catalytic Converterº in the
Owner's manual.)
Fuel Cap, Fuel Lines, and Fuel Tank
Inspection
Inspect the fuel tank, the fuel cap and the fuel lines every
60,000 miles (96,000 km) for damage which could cause
leakage.
Inspect the fuel cap and the gasket for correct sealing and
physical damage. Replace any damaged parts.
Drive Belt Inspection
Check the serpentine belt driving for cracks, fraying,
wear, and correct tension every 30,000 miles (48,000
km). Replace as necessary.
Wheel Alignment, Balance and Tires
Operation
Uneven or abnormal tire wear, or a pull right or left on a
straight and level road may show the need for a wheel
alignment. A vibration of the steering wheel or seat at
normal highway speeds means a wheel balancing is
needed. Check tire pressure when the tires are ªcoldº
(include the spare).
Maintain pressure as shown in the tire placard, which is
located on the driver's door lock pillar.
Steering System Operation
Be alert for any changes in steering operation. An
inspection or service is needed when the steering wheel
is harder to turn or has too much free play, or if there are
unusual sounds when turning or parking.
Brake Systems Operation
Watch for the ªBRAKEº light coming on. Other signs of
possible brake trouble are such things as repeated pulling
to one side when braking, unusual sounds when braking
or between brake applications, or increased brake pedaltravel. If you note one of these conditions, repair the
system at once.
For convenience, the following should be done when
wheels are removed for rotation: Inspect lines and hoses
for proper hookup, bindings, leaks, crack, chafing etc.
Inspect disc brake pads for wear and rotors for surface
condition.
Inspect other brake parts, including parking brake drums,
linings etc., at the same time. Check parking brake
adjustment.
Inspect the brakes more often if habit or conditions
result in frequent braking.
Parking Brake and Transmission Park
Mechanism Operation
Park on a fairly steep hill and hold the vehicle with the
parking brake only. This checks holding ability. On
automatic transmission vehicles, shifting from ªPº
position to the other positions cannot be made unless the
brake pedal is depressed when the key switch is in the
ªONº position or the engine is running.
WARNING: B E F O R E C H E C K I N G T H E S TA R T E R
SAFETY SWITCH OPERATION BELOW, BE SURE TO
HAVE ENOUGH ROOM AROUND THE VEHICLE.
THEN FIRMLY APPLY BOTH THE PARKING BRAKE
AND THE REGULAR BRAKE. DO NOT USE THE
ACCELERATOR PEDAL. IF THE ENGINE STARTS,
BE READY TO TURN OFF THE KEY PROMPTLY.
TAKE THESE PRECAUTIONS BECAUSE THE
VEHICLE COULD MOVE WITHOUT WARNING AND
POSSIBLY CAUSE PERSONAL INJURY OR
PROPERTY DAMAGE.
Starter Safety Switch Operation
Check by trying to start the engine in each gear while
setting the parking brake and the foot brake. The starter
should crank only in ªPº (Park) or ªNº (Neutral).
Accelerator Linkage Lubrication
Lubricate the accelerator pedal fulcrum pin with chassis
grease.
Steering and Suspension Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts or signs of
wear. Inspect power steering lines and hoses for proper
hookup, binding, leaks, cracks, chafing, etc.
Body and Chassis Lubrication
Lubricate the key lock cylinders, the hood latch, the hood
and door hinges, the door check link, the parking cable
guides, the underbody contact points, and the linkage.
Propeller Shaft Inspection and Lubrication
Check the propeller shaft flange±to±pinion bolts for
proper torque to 63 Nwm (46 lb ft) for front and rear
propeller shaft.

Heating and Ventilation System
General Description
Heater
When the engine is warming up, the warmed engine
coolant is sent into the heater core. The heater system
supplies warm air into the passenger compartment to
warm it up.
Outside air is circulated through the heater core of the
heater unit and then into the passenger compartment. By
controlling the mixture of outside air and heater core air,
the most comfortable passenger compartment
temperature can be selected and maintained.
The temperature of warm air sent to the passenger
compartment is controlled by the temperature control
knob. This knob acts to open and close the air mix door,
thus controlling the amount of air passed through the
heater core.The air selector switch (Mode SW), with its different
modes, also allows you to select and maintain the most
comfortable passenger compartment temperature.
The air source select switch is used to select either
ªFRESHº for the introduction of the outside air, or ªCIRCº
for the circulation of the inside air. When the switch is set
to ªFRESHº, the outside air is always taken into the
passenger compartment. When setting the switch to
ªCIRCº position, the circulation of air is restricted only to
the inside air with no introduction of the outside air and the
air in the passenger compartment gets warm quickly.
However, the switch is normally set to ªFRESHº to
prevent the windshield from clouding.

5. Evacuate, charge and test the system.
Compressor Leaks
If leaks are located around the compressor shaft seal or
shell, replace or repair the compressor.
Recovery, Recycling, Evacuation and
Charging of HFC-134a
Air conditioning systems contain HFC-134a. This is a
chemical mixture which requires special handling
procedures to avoid personal injury.

Always wear safety goggles and protective gloves.

Always work in a well-ventilated area. Do not weld or
steam clean on or near any vehicle-installed air
conditioning lines or components.

If HFC-134a should come in contact with any part of
the body, flush the exposed area with cold water and
immediately seek medical help.

If it is necessary to transport or carry any container of
HFC-134a in a vehicle, do not carry it in the
passenger compartment.

If it is necessary to fill a small HFC-134a container
from a large one, never fill the container completely.
Space should always be allowed above the liquid for
expansion.

HFC-134a and R-12 should never be mixed as their
compositions are not the same.

HFC-134a PAG oil tends to absorb moisture more
quickly than R-12 mineral oil and, therefore, should
be handled more carefully.

Keep HFC-134a containers stored below 40
C
(104
F).WARNING:

SHOULD HFC-134A CONTACT YOUR EYE(S),
CONSULT A DOCTOR IMMEDIATELY.

DO NOT RUB THE AFFECTED EYE(S). INSTEAD,
SPLASH QUANTITIES OF FRESH COLD WATER
OVER THE AFFECTED AREA TO GRADUALLY
RAISE THE TEMPERATURE OF THE
REFRIGERANT ABOVE THE FREEZING POINT.

OBTAIN PROPER MEDICAL TREATMENT AS
SOON AS POSSIBLE. SHOULD THE HFC-134A
TOUCH THE SKIN, THE INJURY MUST BE
TREATED THE SAME AS SKIN WHICH HAS BEEN
FROSTBITTEN OR FROZEN.
Refrigerant Recovery
The refrigerant must be discharged and recovered by
using the J-39500 (ACR4:HFC-134a Refrigerant
Recovery/Recycling/Recharging/System) or equivalent
before removing or mounting air conditioning parts.
1. Connect the high and low charging hoses of the
ACR
4(or equivalent) as shown below.

6. Perform a system leak test:

Charge the system with approximately 200 g
(0.44 lbs) of HFC-134a.

Make sure the high pressure valve of the manifold
gauge is closed.

Check to ensure that the degree of pressure does
not change.

Check for refrigerant leaks by using a HFC-134a
leak detector.

If a leak occurs, recover the refrigerant. Repair the
leak and start all over again from the first step of
evacuation.
7. If no leaks are found, continue charging refrigerant to
the air conditioning system.

Charge the refrigerant until the scale reading
decreases by the amount of the charge specified.
Specified amount: 700 g (1.54 lbs)

If charging the system becomes difficult:
1. Run the engine at idle and close all the vehicle
doors.
2. Turn A/C switch ªONº.
3. Set the fan switch to its highest position.
4. Set the air source selector lever to ªCIRCº.
5. Slowly open the low side valve on the manifold
gauge set.
WARNING: BE ABSOLUTELY SURE NOT TO OPEN

General Description
When servicing the compressor, keep dirt or foreign
material from getting on or into the compressor parts and
system. Clean tools and a clean work area are important
for proper service. The compressor connections and the
outside of the compressor should be cleaned before any
ºOn±Vehicleº repair, or before removal of the
compressor. The parts must be kept clean at all times and
any parts to be reassembled should be cleaned with
Trichloroethane, naphtha, kerosene, or equivalent
solvent, and dried with dry air. Use only lint free cloths to
wipe parts.
The operations described below are based on bench
overhaul with compressor removed from the vehicle,
except as noted. They have been prepared in order of
accessibility of the components. When the compressor is
removed from the vehicle for servicing, the oil remaining
in the compressor should be discarded and new
compressor oil added to the compressor.
Compressor malfunction will appear in one of four ways:
noise, seizure, leakage or low discharge pressure.
Resonant compressor noises are not cause for alarm;
however, irregular noise or rattles may indicate broken
parts or excessive clearances due to wear. To check
seizure, de±energize the magnetic clutch and check tosee if the drive plate can be rotated. If rotation is
impossible, the compressor is seized. Low discharge
pressure may be due to a faulty internal seal of the
compressor, or a restriction in the compressor. Low
discharge pressure may also be due to an insufficient
refrigerant charge or a restriction elsewhere in the
system. These possibilities should be checked prior to
servicing the compressor. If the compressor is
inoperative, but is not seized, check to see if current is
being supplied to the magnetic clutch coil terminals.
The compressor oil used in the HFC±134a system
compressor differs from that used in R±12 systems.
Also, compressor oil to be used varies according to the
compressor model. Be sure to avoid mixing two or more
different types of oil.
If the wrong oil is used, lubrication will be poor and the
compressor will seize or malfunction.
DKV-14G Type Compressor
DKV±14G is equipped with five±vane rotary compressor.
These vanes are built into a rotor which is mounted on a
shaft.
When the shaft rotates, the vanes built into the cylinder
block assembly are operated by centrifugal force.
This changes the volume of the spare formed by the rotor
and cylinder, resulting in the intake and compression of
the refrigerant gas. The discharge valve and the valve
stopper, which protects the discharge valve, are built into
the cylinder block assembly. There is no suction valve but
a shaft seal is installed between the shaft and head; a
trigger valve, which applies back pressure to the vanes, is
installed in the cylinder block and a refrigerant gas
temperature sensor is installed in the front head.
The specified quantity of compressor oil is contained in
the compressor to lubricate the various parts using the
refrigerant gas discharge pressure.

Diagnosis
Since the problems in steering, suspension, wheels and
tires involve several systems, they must all be considered
when diagnosing a complaint. To identify the symptom,
always road test the vehicle first. Proceed with the follow-
ing preliminary inspections and correct any defects which
are found.
1. Inspect tires for proper pressure and uneven wear.
2. Raise vehicle on a hoist, then inspect front and rear
suspension and steering linkage for loose or
damaged parts.
3. Spin the front wheels. Inspect for out-of-round tires,
out-of-balance tires, loose and/or rough wheel
bearings.

POWER±ASSISTED STEERING SYSTEM2A±9
The hydraulic pump is vane-type design. The submerged
pump has housing and internal parts that are inside the
reservoir and operate submerged in oil. There are two
bore openings at the rear of the pump housing. The larger
opening contains the cam ring, pressure plate, thrust
plate, rotor and vane assembly, and end plate. The
smaller opening contains the pressure line union, flow
control valve and spring.
The flow control orifice is part of the pressure line union.
The pressure relief valve inside the flow control valve
limits the pump pressure.Pressure Switch
When hydraulic pressure reaches 3430 kPa (500 psi), the
pressure switch of the power steering pump closes
causing the Powertrain Control Module (PCM) to actuate
the throttle valve, which increases the engine rpm to
prevent the overload-induced engine speed slow down.
The switch opens when hydraulic pressure drops to 2940
kPa (430 psi).
