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).

The 3S±FE engine is an in±line 4±cylinder engine with the cylinders numbered 1 ± 2 ± 3 ± 4 from the
front.
The crankshaft is supported by 5 bearing inside the crankcase. These bearing are made of aluminum
alloy.
The crankshaft is integrated with 8 weights for balance. Oil holes are placed in the center of the crank-
shaft to supply oil to the connecting rods, bearing, pistons and other components.
This engine's ignition order is 1 ± 3 ± 4 ± 2. The cylinder head is made of aluminum alloy, with a cross
flow type intake and exhaust layout and with pent±roof type combustion chambers. The spark plugs are
located in the center of the combustion chamber.
The intake manifold has 8 independent long ports and utilizes the inertial supercharging effect to im-
prove engine torque at low and medium speeds.
Exhaust and intake valves are equipped with irregular pitch springs made of special valve spring carbon
steel which are capable of functioning no matter what the engine speed.
The intake side camshaft is driven by a timing belt, and a gear on the intake side camshaft engages with
a gear on the exhaust side camshaft to drive it. The cam journal is supported at 5 places between the
valve lifters of each cylinder and on the front end of the cylinder head. Lubrication of the cam journal and
gear is accomplished by oil being supplied through the oiler port in the center of the camshaft.
Adjustment of the valve clearance is done by means of outer shim type system, in which valve adjusting
shims are located above the valve lifters. This permits replacement of the shims without removal of the
camshafts.
The resin timing belt cover is made of 2 pieces. A service hole is provided in the No. 1 belt cover for ad-
justing the timing belt tension.
Piston are made of high temperature±resistant aluminum alloy, and a depression is built into the piston
head to prevent interference with the valves.
Piston pins are the semi±floating type, with the pins fastened to the connecting rods by pressure fitting,
allowing the pistons and pins to float.
The No. 1 compression ring is made of steel and the No. 2 compression ring is made of cast iron. The oil
ring is made of a combination of steel and stainless steel. The outer diameter of each piston ring is
slightly larger than the diameter of the piston and the flexibility of the rings allows them to hug the cylin-
der walls when they are mounted on the piston rings No. 1 and No. 2 work to prevent gas leakage from
the cylinder and oil ring works to clear oil off the cylinder walls to prevent it from entering the combustion
chambers.
The cylinder block is made of cast iron. It has 4 cylinders which are approximately 2 times the length of
the piston stroke. The top of the cylinders is closed off by the cylinder head and the lower end of the cyl-
inders becomes the crankcase, in which the crankshaft is installed. In .addition, the cylinder block con-
tains a water jacket, through which coolant is pumped to cool the cylinders.
The oil pan is bolted onto the bottom of the cylinder block. The oil pan is an oil reservoir made of
pressed steel shoot. A dividing plate is included inside the oil pan to keep sufficient oil in the bottom of
the pan even when the vehicle is tilted. This dividing plate also prevents the oil from making waves when
the vehicle is topped suddenly and thus shifting the oil away from the oil pump suction pipe.

A pressure feeding lubrication system has been adopted to supply oil to the moving parts of this engine.
The lubrication system consists of an oil pan, oil pump, oil filter and other external parts which supply oil
to the moving parts in the engine block The oil circuit is shown in the illustration at the top of the pre-
vious page. Oil from the oil pan is pumped up by the oil pump. After it passes through the oil filter, it is
fed through the various oil holes in the crankshaft and cylinder block. After passing through the cylinder
block and performing its lubricating function, the oil is returned by gravity to the oil pan. A dipstick on the
center left side of the cylinder block is provided to check the oil level.
OIL PUMP
The oil pump pumps up oil from the oil pan and sends it under pressure to the various parts of the en-
gine.
An oil strainer is mounted in front of the inlet to the oil pump. The oil pump itself is a trochoid±type
pump, inside of which is a drive rotor and a driven rotor. 'When the drive rotor rotates, the driven rotor
rotates in the same direction, and since the axis of the driven rotor shaft is different from the center of
the driven rotor, the space between the two rotors is changed as they rotate. Oil is drawn in when the
space is wide and is discharged when the space in narrow.
OIL PRESSURE REGULATOR (RELIEF VALVE)
At high engine speeds, the engine oil supplied by the oil pump exceeds the capacity of the engine to
utilize it.
For that reason, the oil pressure regulator works to prevent an oversupply of oil. During normal oil sup-
ply, a coil spring and valve keep the by±pass closed, but when too much oil is being fed, the pressure
become extremely high, overpowering the force of the spring and opening the valves. This allows the
excess oil to flow through the valve and return to the oil pan.
OIL FILTER
The oil filter is a full flow type filter with a built±in paper filter element, Particles of metal from wear, air-
born dirt, carbon and other impurities can get in the oil during use and could cause accelerated wear or
seizing if allowed to circulate through the engine. The oil filter, integrated into the oil line, removes these
impurities as the oil passes through it. The filter is mounted outside the engine to simplify replacement of
the filter element.
A relief valve is also included ahead of the filter element to relieve the high oil pressure in case the filter
element becomes clogged with impurities. The relief valve opens when the oil pressure overpowers the
force of the spring. Oil passing through the relief valve by±passes the oil filter and flows directly into the
main oil hole in the engine.
