BLEEDING OF CLUTCH SYSTEM
HINT: If any work is done on the clutch system or if air
is suspected in the clutch lines, bleed the system of air.
CAUTION: Do not let brake fluid remain on a painted sur-
face. Wash it off immediately.
1. FILL CLUTCH RESERVOIR WITH BRAKE FLUID
Check the reservoir frequently. Add fluid if necessary.
2. CONNECT VINYL TUBE TO BLEEDER PLUG
Insert the other of the tube in a half±filled container of
brake fluid.
3. BLEED CLUTCH LINE
(a) Slowly pump the clutch pedal several times.
(b) While depressing the pedal, loosen the bleeder plug
until the fluid starts to run out. Then close the bleeder
plug.
(e) Repeat this procedure until there are no more air
bubbles in the fluid.

CHECK CLUTCH PEDAL
1. CHECK THAT PEDAL HEIGHT IS CORRECT
(See page CL±3)
2. CHECK THAT PEDAL FREEPLAY AND PUSH ROD
PLAY ARE CORRECT
(See page CL±3)
CHECK CLUTCH START SYSTEM
(a) Check that the engine does not start when the clutch
pedal is released.
(b) Check that the engine starts when the clutch pedal is fully
depressed.
If necessary, inspect the clutch start switch.
INSPECTION OF CLUTCH START
SWITCH
INSPECT CONTINUITY OF CLUTCH START SWITCH
(a) Check that there is continuity between terminals when
the switch in ON (pushed).
(b) Check that there is no continuity between terminals
when the switch is OFF (released).
If continuity is not as specified, replace the switch.

DESCRIPTION
This engine utilizes a pressurized water forced circulation cooling system which includes a thermostat
equipped with a by±pass valve mounted on the inlet side.
± COOLING SYSTEMDescriptionCO±2

The cooling system is composed of the water jacket (inside the cylinder block and cylinder head), radiator,
water pump, thermostat, electric fan, hoses and other components.
Coolant which is heated in the water jacket is pumped to the radiator, through which an electric 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 and combustion chambers which
become heated during engine operation.
RADIATOR
The radiator performs the function of cooling the coolant which has passed through the water jacket and be-
come hot, and it 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 filler inlet. It also has a hose attached through which excess coolant or steam can flow. The lower
tank has an outlet and drain cock for the coolant. 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 coolant in the
tubes.
The air sucked through the radiator by the electric fan, as well as the wind generated by the vehicle's travel,
passes through the radiator, cooling the coolant. Models with automatic transmission include an automatic
transmission fluid cooler built into the lower tank of the radiator. A fan with an electric motor is mounted be-
hind the radiator to assist the flow of air through the radiator. The fan operates when the coolant tempera-
ture becomes high in order to prevent it from becoming too high.
RADIATOR CAP
The radiator cap is a pressure type cap which seals the radiator, resulting in pressurization of the radiator as
the coolant expands. The pressurization prevents the coolant from boiling even when the coolant tempera-
ture exceeds 100°C (212°F). A relief valve (pressurization valve) and a vacuum valve (negative pressure
valve) are built into the radiator cap. The relief valve opens and lets steam escape through the overflow pipe
when the pressure generated inside the cooling system exceeds the limit (coolant temperature: 110 ±
120°C, 230 ± 248°F, pressure; 0.3 ±1.0 kg/cm
2, 4.3 ±14.2 psi, 29.4 ± 98.1 kPa). The vacuum valve opens to
alleviate the vacuum which develops in the coolant system after the engine is stopped and the coolant tem-
perature drops.
The valves's opening allows the coolant in the reservoir tank to return to the cooling system.
RESERVOIR TANK
The reservoir tank is used to catch coolant which overflows the cooling system as a result of volumetric ex-
pansion when the coolant is heated. The coolant in the reservoir rank returns to the radiator when the cool-
ant temperature drops, thus keeping the radiator full at all times and avoiding needless coolant loss. Check
the reservoir tank level to find out if the coolant needs to be replenished.
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 timing belt.
THERMOSTAT
The thermostat has a wax type by±pass valve and is mounted in the water inlet housing. The thermostat in-
cludes a type of automatic valve operated by fluctuations in the coolant temperature. This valve closes when
the coolant temperature drops, preventing the circulation of coolant through the engine and thus permitting
the engine to warm up rapidly. The valve opens when the coolant temperature has risen, allowing the cir-
culation of coolant. 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 temperature of 82°C (180°F).

3. (3S±FE)
REPLACE ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION: To avoid the danger of being burned, do not re-
move it while the engine and radiator are still hot
as fluid and steam can be blown out under pressure.
(b) Drain the coolant from the .radiator and engine drain cocks.
(Engine drain cock at the right rear of engine block.)
(c) Close the drain cocks.
Torque (Engine drain cock):
130 kg±cm (9 ft±Ib, 13 N±m) HINT: If the engine tends to overheat, removal of the
thermostat will adversely effect cooling efficiency.
CHECK AND REPLACEMENT OF
ENGINE COOLANT
1. CHECK ENGINE COOLANT LEVEL AT RESERVE TANK
The coolant level should be between the ºLOWº and
ºFULLº lines.
If low, check for leaks and add coolant up to the ºFULLº
line.
Dirt, leaves or insects on radiator or condenser
Hoses, Water pump, thermostat housing, radiator,
heater, core, plugs or head gasket leakage
Thermostat faulty
Incorrect ignition timing
Electric cooling system faulty
Radiator hose plugged or rotted
Water pump faulty
Radiator plugged or cap faulty
Cylinder head or block cracked or water passage
clogged
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 cool-
ant should be free from oil.
If excessively dirty, replace the coolant.

Reset tinning
Inspect electric cooling system
