6-3. INSPECTION OF COMPONENTS
Thermostat
1) Make sure that air bleed valve of thermostat
is clear. Should this valve be clogged, engine
would tend to overheat.
Fig. 6- 16
1. Air bleed valve
2) Check valve seat for some foreign matters
3) Check thermostatic movement of wax pellet
being stuck which prevent valve from
seating tight.
as follows:
Immerse thermostat in water, and heat
water gradually.
Check that valve starts to open at specifi-
cation temp.
If valve starts to open at a temperature
substantially below or above, thermostat
unit should be replaced with a new one.
Such a unit, if reused, will bring about
overcooling or overheating tendency.

Radiator
If the water side of the radiator is found exces-
sively rusted or covered with scales, clean it
by flushing with the radiator cleaner compound.
This flushing should be carried out at regular
intervals for scale or rust formation advances
with time even where a recommended type of
coolant is used. Periodical flushing will prove
more economical.
Inspect the radiator cores and straighten the
flattened or bent fins, if any. Clean the cores,
removing road grimes and trashes.
Excessive rust or scale formation on the wet side
of the radiator lowers the cooling efficiency.
Flattened or bent fins obstruct the flow of air
through the core to impede heat dissipation.

NOTE:
Do not disassemble water pump.
If any repair is required on pump, replace it
as assembly.
l Rotate water pump by hand to check for
smooth operation.
If pump does not rotate smoothly or makes
an abnormal noise, replace it.

REINSTALLATION
Water Pump
1) Install new pump gasket to cylinder block.
2) Install water pump to cylinder block.
Tightening torque

1 .O - 1.3 kg-m
7.5 - 9.0 lb-ft
After installing water pump, install rubber seal
between water pump and oil pump, and another
between water pump and cylinder head.
Fig, 6-201. Rubber seal
3) Install belt tensioner plate, tensioner,
tensioner spring, timing belt and timing belt
outside cover.
NOTE:
l Special care must be used when installing belt
tensioner and timing belt. Be sure to refer to
p. 3-48 of this manual.
l Torque each bolt and nut to specification.
4) Install crankshaft pulley, water pump
pulley, pump drive belt, cooling fan &
clutch and radiator shroud.
5) Adjust intake and exhaust valve lashes.
(For adjustment and related data, refer to
p. 3-53 of this manual).
6) Adjust water pump belt tension.
(Refer to P. 6-10).
7) Connect negative cable at battery.
8) Fill the cooling system.
Thermostat
1) When positioning the thermostat on the
intake manifold, be sure to bring its air brea-
ther valve (iJ to front side of the engine.
Fig. 6-21
2) Install new gasket and
intake manifold.
3) Fill the cooling system.

Cooling Fan, Fan clutch and Water Pump Belt
Once cooling fan, fan clutch or water pump belt
has been removed, make sure to tighten bolts
and nuts securely in reinstallation and adjust
pump belt tension to specification. (For specifi-
ed tension, refer to p. 6-10.)

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.).

3) If belt is too tight or too loose, adjust it to
proper tension by displacing alternator
position.

bolt.
WARNING:
All adjustments described above are to be
performed with ENGINE NOT RUNNING.

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.

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.

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.
