NOTE:
Steps 1) - 6) outlined above must be performed
with ENGINE NOT RUNNING. For step 7),
be sure to have adequate ventilation while
engine is running
It is recommended to use engine oil of SE or
SF class.
NOTE:For temperatures below
32”F(O”C), it is highly
recommended to use SAE 5W-30 oil.

8) Check oil filter and drain plug for oil leakage.
5. COOLING SYSTEM HOSES AND
CONNECTIONS INSPECTION
1) Visually inspect cooling system hoses for any
evidence of leakage and cracks. Examine them
for damage, and check connection clamps
for tightness.
2) Replace all hoses which show evidence of
leakage, cracks or other damage. Replace all
clamps which cannot maintain proper tight-
ness.
6. ENGINE COOLANT CHANGE
WARNING:
To help avoid danger of being burned, do
not remove radiator cap while engine and
radiator are still hot. Scalding fluid and
steam can be blown out under pressure if
the cap is taken off too soon.
1) Remove radiator cap when engine is cool.
2) Loosen radiator drain plug @
to drain
coolant.
3) Remove reservoir tank 0, which is on the
side of radiator, and drain.
4) Tighten plug
@ securely. Also reinstall reser-
voir tank.

3) Check propeller shaft (No. 1, No. 2, No. 3)
flange yoke bolts for tightness, and retighten
them as necessary:

42. TRANSMISSION, TRANSFER,
DIFFERENTIAL OIL INSPECTION
AND CHANGE
[I nspectionl
1) Inspect transmission case, transfer case and
differential housing for evidence of oil leakage.
Repair leaky point if any.
2) Make sure that the car is placed level for oil
level check.
3) Remove each level plug of transmission,
transfer and differential (front and rear).
In any of these cases, oil level can be checked
roughly by means of level plug hole. That is,
,if oil flows out of level plug hole or if oil
level is found up to hole when level plug is
removed, oil is properly filled.
If oil is found insufficient, pour specified
amount of specified oil as given in the below
table.
[Change]
Oil change procedure is as follows.
Place the car level and drain oil by removing
drain plug. Pour specified amount of specified
oil as in the below table and tighten drain plug
and filler plug to specified torque.
It is highly recommended to use SAE 75W-90
gear oil.

Radiator Cap
A pressure-vent cap is used on the radiator. The
cap contains a pressure valve and vacuum valve.
The pressure valve is held against its seat by a
spring of pre-determined strength which protects
the cooling system by relieving the pressure if
the pressure in cooling system rises by 0.9
kg/cm2 (12.8 psi, 90 kPa). The vacuum valve is
held against its seat by a light spring which
permits opening of the valve to relieve vacuum
created in the system when it cools off and
which otherwise might cause the radiator to
collapse.
The cap has its face marked 0.9, which means
that its pressure valve opens at 0.9 kg/cm2
(12.8 psi, 90 kPa).
NOTE:
Do not remove radiator cap to check engine
coolant level; check coolant visually the see-
through water reservoir tank.
Coolant should be added only to reservoir tank
as necessary.
4
WARNING:
As long as there is pressure in the cooling
system, the temperature can be considerab-
ly higher than the boiling temperature of
the solution in the radiator without causing
the solution to boil. Removal of the
radiator cap whileengine is hot and pressure
is high will cause the solution to boil
instantaneously and possibly with explosive
force, spewing the solution over engine,
fenders and person removing cap. If the
solution contains flammable anti-freeze
such as alcohol (not recommended for use
at any time), there is also the possibility of
causing a serious fire.

Water Reservoir Tank
A “see-through” plastic reservoir tank is connect-
ed to the radiator by a hose. As the car is
driven, the coolant is heated and expands. The
portion of the coolant displaced by this ex-
pansion flows from the radiator into the reservoir
tank.
When the car is stopped and the coolant cools
and contracts, the displaced coolant is drawn
back into the radiator by vacuum.
Thus, the radiator is kept filled with coolant to
the desired level at all times, resulting in increas-
ed cooling efficiency.
Coolant level should be between “FULL” and
“LOW’ marks on the reservoir tank.
Coolant should be added only to the reservoir
tank as necessary.

Oil Level
Oil level must be checked with car held in
horizontal position in both front to rear and side
to side directions.
Oil level plug and oil filler plug are one and the
same as shown in figure.
If oil flows out of filler plug hole or if oil level is
found up to hole when plug is removed, amount
of oil is appropriate. Replenish oil if noted as
insufficient.
Oil and Oil Capacity
Whenever car is lifted up for any service includ-
ing oil change,make sure to check around
transfer gear box for oil leakage. Correct defects,
if any, and change or refill oil.
