OB-6 MAINTENANCE AND LUBRICATION
BRAKE SYSTEMS OPERATION
Watch for the "BRAKE" 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 pedal travel. 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 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
"P" position to the other positions cannot be made
unless
the brake pedal is depressed when the key
switch is in
"ON" position or the engine running.
WARNING
•
Before checking starter 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
(AUTOMATIC TRANSMISSION)
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 "P" (Park) or "N"
(Neutral).
STARTER SAFETY SWITCH OPERATION
(MANUAL TRANSMISSION)
To check, place the shift lever in "Neutral", push
the clutch pedal halfway and try to start. The starter
should not crank. The starter should crank only
when the clutch pedal is fully depressed.
ACCELERATOR LINKAGE LUBRICATION
Lubricate the accelerator pedal fulcrum pin with
chassis grease.
STEERING AND SUSPENSION
INSPECTION
Inspect 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
Lubricate sliding yoke and universal joints with
grease containing MOS2 (disulfide molybdenum
type grease) at the interval shown in the
Maintenance Schedule. Check for play in normal
direction of rotation of sliding yoke and universal
joints. Also check
propeller shaft flange-to-pinion
bolts for proper torque of 63 N·m (46 lb·ft) for front
and rear propeller shaft.
AUTOMATIC TRANSMISSION FLUID
INSPECTION
Check the lubricant level every 7,500 miles (12,000
km) and add lubricant
if necessary.
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.
AUTO CRUISE CONTROL INSPECTION
Check to see if the clearance between cruise link and
accelerator is normal. Also check that the vacuum
hoses are routed and connected properly.
CLUTCH LINES AND HOSES INSPECTION
Check lines and hoses for proper attachment,
binding, leaks, cracks, chafing, deterioration, etc.
Any questionable parts should be replaced or
repaired at once. When abrasion or wear is evident
on lines or hoses, the cause must be corrected.

68 - 2 ENGINE COOLING
The cooling system is a pressurized Engine Coolant
(EC) forced circulation type which consists of water
pump, thermostat cooling fan, radiator and other
components. The automatic transmission fluid is
cooled by the EC in radiator.
WATER PUMP

The
EC pump is a centrifugal impeller type and is
driven by timing belt. (Fig.68-2)
THERMOSTAT
Jiggle valve
Fig. 68-3
The
thermostat is a wax pellet type with a jiggle
valve and is installed in the thermostat housing.
(Fig.68-3)
RADIATOR
The radiator is a tube type with corrugated fins. In
order to raise the boiling point of coolant, the radiator
is fitted
with a cap in which the valve is operated at
88.2
-117.6 kPa (12.8 - 17.0 psi) pressure. (No oil
cooler
provided for M!f)

•
Relation between Mixing ratio and Freezing
temperature
of the EC varies with the ratio of
anti-freeze solution in water. Proper mixing
ratio can be determined by referring to the
chart. Supplemental inhibitors or additives
claiming to increase cooling capability that have
not been specifically approved by lsuzu are not
recommended for addition to the cooling
system.

ON-VEHICLE SERVICE
DRAINING AND REFILLING COOLING
SYSTEM
Before draining the cooling system, inspect the sys­
tem and perform any necessary service to ensure that
it is clean, does not leak and is in proper working
order. The Engine Coolant (EC) level should be be­
tween the "MIN" and "MAX" lines of reserve tank
when the engine is cold. If low, check for leakage and
add
EC up to the "MAX" line. There should not be any
excessive deposit of rust or scales around the radiator
cap
or radiator filler hole, and the EC should also be
free
from oil. Replace the EC if excessively dirty.
1. Completely drain the cooling system by opening
the drain petcock at the bottom of the radiator.
2. Remove the radiator cap.
W WARNING
To avoid the danger of being burned, do not
remove the cap while the engine and radiator
are still hot. Scalding fluid and steam can be
blown out under pressure.
3. Disconnect all hoses from the EC reserve tank.
Scrub and clean the inside of the reserve tank with
soap and water. Flush it well with clean water,
then drain it. Install the reserve tank and hoses.

4. Refill the cooling system with the EC using a
solution that is at least 50 percent antifreeze but no
more than 70 percent antifreeze.
5. Fill the radiator to the base of the filler neck.
Fill the EC reserve tank to "MAX" line when the
engine is cold.
6. Block the drive wheels and firmly apply the park­
ing brake.
Shift an automatic transmission to "P"
(Park) or a manual transmission to neutral.
7. Remove the radiator cap. Start the engine and
warm it up at 2,500 -3,000 rpm for about 30
minutes.
8. When the air comes out from the radiator filler
neck and the EC level has gone down, replenish
with the EC. Repeat this procedure until the EC
level does not go down. Then stop the engine and
install the radiator cap. Let the engine cool down.
9. After the engine has cooled, replenish with EC up
to the "MAX" line of the reserve tank.
10. Start the engine. With the engine running at 3,000
rpm, make sure there is no running water sound
from the heater core (behind the center console).
11. If the running water sound is heard, repeat steps 7
to 10.

ON-VEHICLE SERVICE
BATTERY CHARGING
Observe the following safety precautions when
charging the battery:
1. Never attempt to charge the battery when the
fluid level is below the lower level line on the
side
of the battery. In this case, the battery
must be replaced.
2. Pay close attention to the battery during the
charging procedure.
Battery charging
should be discontinued or the
rate
of charge reduced if the battery feels hot
to the touch.
Battery charging
should be discontinued or the
rate
of charge reduced if the battery begins to
gas or spew electrolyte from the vent holes.
3. In order to more easily view the hydrometer
blue dot or ring, it may be necessary to jiggle
or tilt the battery.
4. Battery temperature can have a great effect on
battery charging capacity.
5. The sealed battery used on this vehicle may be
either quick-charged or slow-charged in the
same manner
as other batteries.
Whichever method you decide
to use, be sure
that you
completely charge the battery. Never
partially charge the battery.
JUMP STARTING
JUMP STARTING WITH AN AUXILIARY
(BOOSTER)
BATTERY
W CAUTION:
Never push or tow the vehicle in an attempt to
start it.
Serious damage to the emission sys­
tem as
well as other vehicle parts will result.
Treat both the discharged battery and the
booster battery
with great care when using
jumper cables. Carefully follow the jump start­
ing procedure, being
careful at all times to
avoid sparking.
wwARNING:
Failure to carefully follow the jump starting
procedure
could result in the following:
1. Serious personal injury, particulaly to your
eyes.
2. Property damage from a battery explo­
sion, battery acid, or an electrical fire.
3. Damage to the electronic components of
one or both vehicles particularly.
Never expose the battery to an open flame or elec­
trical
spark. Gas generated by the battery may catch
fire
or explode.
Remove any rings, watches, or other jewelry before
working around the battery. Protect
your eyes by
wearing
an approved set of goggles.
Never allow battery fluid to come in contact with
your eyes or skin.
Never
allow battery fluid to come in contact with
fabrics or painted surfaces.
Battery
fluid is a highly corrosive acid.
Should battery fluid come in contact with your eyes,
skin, fabric, or a painted surface,
immediately and
thoroughly rinse the affected area with clean tap
water. Never
allow metal tools or jumper cables to come
in contact with the positive battery
terminal, or any
other
metal surface of the vehicle. This will protect
against a short circuit.
Always keep batteries out of the reach of young
children.
JUMP STARTING PROCEDURE
1. Set the vehicle parking brake.
If the vehicle is equipped with an automatic
transmission,
place the selector lever in the
"PARK" position.
If the vehicle is equipped with a manual trans­
mission
place the shift lever in the "NEUTRAL"
position.
Turn
"OFF" the ignition.
Turn
"OFF" all lights and any other accessory
requiring
electrical power.
2. Look at the built-in hydrometer.
If the indication area of the built-in hydrometer
is
completely clear, do not try to jump start.
3. Attach the end of one jumper cable to the posi­
tive
terminal of the booster battery.
Attach the other end
of the same cable to the
positive
terminal of the discharged battery.
Do not allow the vehicles to touch each other.
This
will cause a ground connection, effectively
neutralizing
the charging procedure.
Be sure that the booster battery has a 12 volt
rating.
4. Attach one end of the remaining cable to the
negative
terminal of the booster battery.
Attach the other end
of the same cable to a
solid engine ground (such as the air condition­
ing compressor bracket or the generator
mounting bracket)
of the vehicle with the dis­
charged battery.
This ground connection must be at
least 450
mm (18 in) from the battery of the vehicle
whose battery is being charged.
