GENERAL REPAIR INSTRUCTIONS
1. If a floor jack is used, the following precautions
are recommended.
Park
vehicle on level ground, "block" front or
rear wheels, set jack against the recommended
lifting points (see "Lifting instructions" in this
section), raise
vehicle and support with chassis
stands and then perform 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 lsuzu parts.
7. Used cotter pins, plastic clips, gaskets, 0-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 pre­
vent 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.

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
"ADD" mark and between the "ADD" and
"FULL" 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 reservoir and add if necessary.
Power steering system reservoir level-Check
and keep at
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 l~vel 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 (Fig. OB-1).
Always change the oil and the oil filter as soon as
possible after driving in a dust storm.
MAINTENANCE AND LUBRICATION OB-5
ENGINE COOLING SYSTEM INSPECTION
Inspect coolant/anti-freeze. If 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 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 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
"Engine Exhaust Gas Safety" and "Three Way
Catalytic Converter" in 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 belts driving the steering oil pump, the air
conditioning compressor, and the generator
for
cracks, fraying, wear, and correct tension every 30,000
miles (48,000 km). Adjust or 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 "cold" (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 action. 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.

CHASSIS ELECTR1CAL 8-205
WINDSHIELD WIPER/WASHER AND REAR WIPER/WASHER
GENERAL DESCRIPTION
~ The circuit consists of the starter switch, wiper & washer switches, wiper motors, washer motors and inter­
mittent relays for both the windshield and some models the rear wipers.
When the
wiper & washer switch is turned on with the starter switch on, the battery voltage is applied to the
wiper motor to activate the wiper.
The washer
motor squirts glass cleaning fluid while the washer switch is being pushed. The intermittent relay
is used
to control motion of the wiper.
OPERATION OF WINDSHIELD WIPER MOTOR (When wiper & washer SW is at "LO" or ''I NT"
position)

HEADLIGHT WIPER/WASHER
GENERAL DESCRIPTION
The circuit consists of the starter switch, headlight wiper/washer switch, headlight wiper motor and washer
motor. By pushing the headlight wiper/washer switch, with the starter switch on, the wiper will make 5 strokes,
with washer solution applied between each of the first 4 strokes, regardless of the length of time the switch is
held down.
The washer nozzle is installed to the wiper blade, and the washer motor draws fluid from the same reservoir
as the windshield washer.
OPERATION OF HEADLIGHT WIPER

set
to ON and headlight
wiper starts to operate.
