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.

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
fastener 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 specifications. Following these
instructions can help you avoid damage to parts and
systems.

Front Disc Brake Pads Inspection
Check the outer pad by looking at each caliper from
above. Check the thickness on the inner pad by looking
down through the inspection hole on the top of the caliper.
Whenever the pad is worn to about the thickness of the
pad base, the pad should be removed for further
measurements. The pad should be replaced anytime the
pad thickness (1) is worn to within 1.00 mm (0.039 in) of
the pad itself.
Wear indicators are installed on disc brake pads, disc
brake pads need replacement when the wear indicator is
heard.
