Radiator6-5. MAINTENANCE SERVICE
1) Tighten bolts securely for proper installa-
tion. Also, fix joints of 2 hoses with clamps.
Fig. 6-22
2) Install radiator shroud and cooling fan &
clutch at the same time.
3) Tighten shroud bolts and fan clutch nuts.
4) Adjust water pump belt tension.
5) Fill specified amount of coolant.
Water Pump Belt
1) Inspect belt for cracks, cuts, deformation,
wear and cleanliness. If it is necessary to
replace belt, refer to ~6-5 for procedure.
2) Check belt for tension. Belt is in proper
tension when it deflects 6 to 9 mm (0.24 -
0.35 in.) under thumb pressure (about 10 kg
or 22 lb.).

B. Undercharged Battery a. Voltmeter
This condition, as shown by slow cranking or indicator clear with red dot, can be caused by
one or more of the following conditions even
though the indicator lamp may be operating
normally. The following procedures also apply
to cars with a voltmeter.
1) Insure that the undercharged condition has
not been caused by accessories left on for
extended period.
2) Check drive belt for proper tension.
3) If a battery defect is suspected, refer to
latter part of this section, p. 10-l 0 - p, 1 O-
11.
4) Inspect wiring for defects. Check all connec- tions for tightness and cleanliness, including
slip connectors at alternator and bulkhead,
and battery cable connections at battery,
starter and ignition ground cable.
5) Connect voltmeter and ammeter as shown inthe diagram below.
Set between alternator (B) terminal and
ground.
b. Ammeter
Set between alternator (B) terminal and
battery (+) terminal.
6) Current and voltage measurements
a. No-load check
Run engine from idling up to 2,000 r/min
(rpm) and read meters.
NOTE:
Consideration should be taken that the voltage
will vary somewhat with regulator case tempe-
rature.

GENERAL DESCRIPTION
The battery has three major functions in the
electrical system. First, it is a source of electrical
energy for cranking the engine. Second it acts as
a voltage stabilizer for the electrical system. And
third, it can, for a limited time, provide energy
when the electrical load exceeds the output of
the generator.
Each new car shipped from the factory is
fitted with following battery.
IModel55BzR=l(NXIOO-S6 6))
1 Rated capacityt 137 kC (38 Ah)/5HR j
This battery is completely sealed, except for six
small vent holes in the top. These vent holes
allows the small amount of gas produced in the
battery to escape. This sealed battery has a
built-in temperature compensated indicator in
the top of the battery.
Fig. lo-22
CARE OF THE BATTERY
[Electrolyte freezing]
The freezing point of electrolyte depends on its
specific gravity. Since freezing may ruin a
battery, it should be protected against freezing
by keeping it in a fully charged condition.

Steering Gear Box
Check steering gear box for evidence of oil
leakage. If leakage is found, repair or replace
and then refill specified oil to specified level.
Refer to“18-5 INSPECTION OF COMPO-
NENT” in this section for steering gear box oil.

Tires[Tire wear indicator]
When replacement is necessary, the original
equipment type tire should be used. Refer to
Tire Placard.
Check wear indicator, and replace tire when its
wear is the same level as the indicator.
Replacement tires should be of the same size,
load range and construction as those originally
on the car. Use of any other size or type tire
may affect ride, handling, speedometer/odometer
calibration, vehicle ground clearance and tire or
snow chain clearance to body and chassis.
NOTE:
NOTE:
Do not mix different types of tires on the same
car such as radial, bias and bias-belted tires
except in emergencies, because car handling may
be seriously affected and may result in loss of
control.
The mud & snow tire has a platform ttr indicate
wear in addition to tire tread wear indicator.
It shows up when 50% of tire tread is worn out.
When driving on muddy or snowy roads, check
if its wear is the same level as the platform and
if it does, replace the tire.
It is recommended that new tires be installed in
pairs on the same axle. If necessary to replace
only one tire, it should be paired with the tire
having the most tread, to equalize braking
traction.
[Inspection]
l Check tires for uneven or excessive wear, or
damage. If defective, replace.
l Check inflating pressure of each tire and,
as necessary, adjust pressure to specification.
l Check wheels for dent, crack or other damage.
l Check wheel nuts for tightness.

21-9. 4 WHEEL DRIVE LAMP21-10. SEAT BELT WARNING LAMP/
BUZZERThe 4 wheel drive lamp circuit consists of the 4
wheel drive indicator lamp switch installed to
the transfer and the lamp inside the combination
meter.
The 4WD switch so operates that it is switched
ON when transfer gear shift control lever is
shifted to “4H” or “4L” position.
The seat belt warning lamp/buzzer circuit is a
system to light and sound the lamp and buzzer
respectively for several seconds, urging the
driver to wear his seat belt. After several seconds
passed, the lamp goes OFF and the buzzer stops
sounding whether the seat belt is worn or not.
