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±5 MAINTENANCE AND LUBRICATION
Explanation of Complete Vehicle
Maintenance Schedule
Brief explanations of the services listed in the preceding
Maintenance Schedule are presented below.
Replace all questionable parts and note any necessary
repairs as you perform these maintenance procedures.
Front and Rear Axle Lubricant
Replacement
Check the lubricant level after every 7,500 miles (12,000
km) of operation and add lubricant to level of filler hole if
necessary.
Replace the front and rear axle lubricant at 15,000 miles
(24,000 km) and 30,000 miles (48,000 km) and after
every 30,000 miles (48,000 km) of operation thereafter.
Air Cleaner Element Replacement
Replace the air cleaner under normal operating
conditions every 30,000 miles (48,000 km).
Operation of the vehicle in dusty areas will necessitate
more frequent replacement.
Spark Plug Replacement
Replace the plugs at 100,000 miles (160,000 km)
intervals with the type specified at the end of this section.
Cooling System Service
Drain, flush and refill system with new engine coolant.
Refer to
ªRecommended Fluids and Lubricantsº in this
section, or ENGINE COOLING (SEC.6B).
Timing Belt Replacement
Replacement of the timing belt is recommended at every
100,000 miles (160,000 km).
Failure to replace the timing belt may result in serious
damage to the engine.
Valve Clearance Adjustment
Incorrect valve clearance will result in increased engine
noise and reduced engine output.
Retorque the camshaft bracket bolts before checking and
adjusting the valve clearance.
Check and adjust the valve clearance whenever
increased engine noise is heard.
Tire Rotation
Rotate tires every 7,500 miles (12,000 km).
Front Wheel Bearings Lubricant
Replacement (Vehicles Produced Before
July/31/2001)
Clean and repack the front wheel bearings at 30,000
miles (48,000 km) intervals.
Refer to DRIVE SHAFT SYSTEM (SEC. 4C).
Front Wheel Bearings Check (Vehicles
Produced After Aug./1/2001)
Inspect hub unit bearing at every 60,000 miles (96,000
km).
If there is abnormal condition, replace hub unit bearing.
Radiator Core and Air Conditioning
Condenser Cleaning
Clean the front of the radiator core and air conditioning
condenser, at 60,000 miles (96,000 km) intervals.
Fluid Level Check
A fluid loss in any system (except windshield
washer) may indicate a problem. Repair the system
at once.
Engine oil level
Check level and add if necessary. The best time to check
the engine oil level is when the oil is warm. After stopping
the engine with the vehicle on a level surface, wait a few
minutes for the oil to drain back to the oil pan. Pull out the
oil level indicator (dipstick). Wipe it clean and push the oil
level indicator back down all the way. Pull out the oil level
indicator, keeping the tip down, and look at the oil level on
it.
Add oil, if needed, to keep the oil level above the ªADDº
mark and between the ªADDº and ªFULLº marks in the
operating range area. Avoid overfilling the engine since
this may cause engine damage. Push the oil level
indicator back down all the way after taking the reading.
If you check the oil level when the oil is cold, do not run the
engine first. The cold oil will not drain back to the pan fast
enough to give a true oil level.
Engine coolant level and condition
Check engine coolant level in the coolant reservoir and
add engine coolant if necessary. Inspect the engine
coolant and replace it if dirty or rusty.
Windshield washer fluid level
Check washer fluid level in the reservoir and add if
necessary.
Power steering system reservoir level
Check and keep at the proper level.
Brake master cylinder reservoir level
Check fluid. Keep fluid at proper level. A low fluid level can
indicate worn disc brake pads which may need to be
serviced.
Hydraulic clutch system
Check fluid level in the reservoir. Add fluid as required.
Battery fluid level
Check fluid level in the battery.
Fluid Leak Check
Check for fuel, water, oil or other fluid leaks by looking at
the surface beneath the vehicle after it has been parked
for a while. Water dripping from the air conditioning
system after use is normal. If you notice gasoline fumes or
fluid at any time, locate the source and correct it at once.
Engine Oil and Oil Filter Replacement
Always use API SE, SF, SG, SH or ILSAC GF±1 quality
oils of the proper viscosity.
When choosing an oil, consider the range of
temperatures the car will be operated in before the next oil
change. Then, select the recommended oil viscosity from
the chart.
Page 20 of 2100
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.

0B±7 MAINTENANCE AND LUBRICATION
Automatic Transmission Fluid
Replacement
Under harsh operating conditions, such as constant
driving in heavy city traffic during hot weather, or in hilly or
mountainous terrain, change the transmission fluid and
service the sump filter after every 20,000 miles (32,000
km) of operation.
More over, the remaining life percentage of ATF can be
estimated by using TECH±II as an auxiliary tool to judge
the right time for ATF replacement.
The remaining life percentage is calculated from ATF'S
heat history. When it is close to 0%, ATF replacement is
recommended.
Auto Cruise Control Inspection
Check to see if the clearance between cruise link and
accelerator link is normal. Also check that the connected
properly.
Accelerator Linkage Inspection
Inspect for interference, binding, and damaged or
missing parts. Check accelerator pedal for smooth
operation and even pedal effort. Replace parts as
needed.
