GENERAL REPAIR INSTRUCTIONS
1. Use fender, seat and floor covers to keep the vehicle clean
and prevent damage.
2.
3. During disassembly, keep parts in order to facilitate
reassembly.
Observe the following:
(a)
(b) Before performing electrical work, disconnect ‘the
negative (-1 cable from the battery terminal.
If it is necessary to disconnect the battery for inspec-
tion or repair, always disconnect the cable from the
negative (-) terminal which is grounded to the vehi-
cle body.
(c) To prevent damage to the battery terminal post,
loosen the terminal nut and raise the cable straight up
without twisting or prying it.
(d) Clean the battery terminal posts and cable terminals
with a shop rag. Do not scrape them with a file or
other abrasive object.
(e)
(f) Install the cable terminal to the battery post with the
nut loose, and tighten the nut after installation. Do
not use a hammer to tap the terminal onto the post.
Be sure the cover for the positive (+I terminal is pro-
perly in place.
4.
5. Check hose and wiring connectors to make sure that they
are secure and correct.
Non-reusable parts
(a)’ Always replace cotter pins gaskets, O-rings, oil seals,
etc. with new ones.
(b) Non-reusable parts are indicated in the component
illustrations by the “+” symbol.
6. Precoated Parts
Precoated parts are the bolts, nuts, etc. which are coated
with a seal lock adhesive at the factory.
(a) If a precoated part is retightened, loosened or caused
to move in any way, it must be recoated with the
specified adhesive.

. COOLING SYSTEM - Description
co;3
RESERVOIR TANK
The reservoir tank is used to catch coolant
which overflows the cooling systein as a result of
volumetric expansion when the coolant is heated.
The coolant in the reservoir tank returns to the
radiator when the coolant temperature drops, thus
keeping the radiator full at all times and avoiding
needless coolant loss. Check the reservoir tank
level to learn if the coolant needs to be rep-
lenished.
WATER PUMP
The water pump is used for forced circulation of
coolant through the cooling system. It is mounted
on the front of the cylinder block and driven by a
V-ribbed belt,
THERMOSTAT I The cooling system is composed of the water
jacket (inside the cylinder block and cylinder head),
radiator, water pump, thermostat, cooling fan,
hoses and other components.
Coolant which is heated in the water
jacket is
pumped to the radiator, through which a cooling
fan blows air to cool the coolant as it passes
through. Coolant which has been cooled is then
sent back to the engine by the water pump, where
it cools the engine.
The water jacket is a network of channels in the
shell of the cylinder block and cylinder head
through which coolant passes. It is designed to
provide adequate cooling of the cylinders are com-
bustion chambers which become the hottest dur-
ing engine operation.
F(/ “ IATOR
The radiator performs the function of cooling
the coolant which has passed through the water
jacket and become hot, and is mounted in the front
of the vehicle. The radiator consists of an upper
tank and ‘lower tank, and a core which connects
the two tanks. The upper tank contains the inlet for
coolant from the water jacket and the filter inlet. It
also has a hose attached through which excess
coolant or steam can flow. The lower tank contains
the outlet for coolant and the drain cock. The core
contains many tubes through which coolant flows
from the upper tank to the lower tank as well as
cooling fins which radiate heat away from the coo-
lant in the tubes. The air sucked through the radia-
tor by cooling fan, as well as the wind generated
by the vehicle’s travel, passes through the radia-
tor, cooling it. Models with automatic transmission
incrl*-le an automatic transmission fluid cooler built
in:.
.le lower tank of the radiator.
RADIATOR CAP
The radiator cap is a pressure type can which
seals the radiator, resulting in pressurization of the
radiator as the coolant expands. The pressuriza-
tion prevents the coolant from boiling even when
the coolant temperature exceeds 100°C. A relief
valve (pressurization valve) and a vacuum valve
(negative pressure valve) are built into the radiator
zap. The relief valve opens and lets steam escape
:hrough the overflow pipe when the pressure
3enerated inside the cooling system exceeds the
imit (coolant temperature:
110 - 1 20°C, (230
- 248”F), pressure; 0.3 - 1 .O kg/cmz, (4.3 - 14.2
)si, 29.4 - 98.1 kPa). The vacuum valve opens to
3ljeviate the vacuum which develops in the coolant
system after the engine is stopped and the coolant
emperature drops. The valve’s opening allows the
)ressure in the cooling system to return to the
Qclant in the reservoir tank. The thermostat has a wax type and is mounted
in the. water outlet housing. The thermostat
includes a type of automatic valve operated by
fluctuations in the coolant temperature. This valve
closes when the coolant temperature drops, pre-
venting the circulation of coolant through the
engine and thus permitting the engine to warm up
rapidly. The valve opens when the coolant tem-
perature has risen, allowing the circulation of coo-
lant. Wax inside the thermostat expands when
heated and contracts when cooled. Heating the
wax thus generates pressure which overpowers
the force of the spring which keeps the valve
closed, thus opening the valve. When the wax
cools, its contraction causes the force of the
spring to take effect once more, closing the valve.
The thermostat in this engine operates at a tem-
perature of 88”C(19O”F).

COOLING SYSTEM i Check and Replacement of Engine Coolant
co-5
._
CHECK AND REPLACEMENT OF
ENGINE COOLANT
1. CHECK ENGINE COOLANT LEVEL AT RESERVE TANK
The coolant level should be between the “LOW” and
“FULL” lines.
If low, check for leaks and add coolant up to the “FULL”
line. .,>‘
2. CHECK ENGINE COOLANT QUALITY
There should not be any excessive deposits of rust or
scales around the radiator cap or radiator filler hole, and
the coolant should also be free from oil.
lf excessively dirty, replace the coolant.
3. REPLACE ENGINE COOLANT
(a) Remove the radiator cap.
(b) Drain the coolant from radiator and engine drain
cocks.(Engine drain is at right rear of cylinder block.)
(cl Close the drain cocks.
(d) Fill system with coolant.
Use a good brand of. ethylene-glycol base coolant, mixed
according to manufactuer’s directions.

cracks and damaged gasket surfaces.
If necessary, replace the water pump or timing belt case,
INSPECT WATER PUMP BEARINQ
Turn the pulley and check that the water pump bearing
moves smoothly and quietly.

INSPECT FLUID COUPLING
Check that the fluid coupling is not damaged and that no
silicon oil leaks.
If necessary, replace the fluid coupling.

l The points shown in the illustration cannot be staked
with the SST. Use a pliers and be careful not to damage
the core plate.
INSPECT FOR WATER LEAKS
(a) Tighten the drain plug.
(b) Plug the oil cooler pipes to prevent any water leakage
into the oil cooler.
(c) Plug the inlet and outlet pipes of the radiator with
SST.
SST 09230-00010
(d) Using a radiator cap tester, apply pressure to the
radiator.
Test pressure: 1.5 kg/cm2 (21 psi, 147 kPa)
(e) Inspect for water leaks.
NOTE: On radiator with resin tanks, there is a clearance
between the core plate and tank plate where a minute
amount of air will remain, giving the apperance of an air
leak when the radiator is submerged in water.
Therefore, before performing the water leak test, first
swish the radiator around in the water until all air bubbles
disappear.
7. PAINT TANK PLATES
NOTE: If the water leak test checks out okay, allow the
radiator to completely dry and then paint the tank plates.
