PRECAUTION
1. Before working on the fuel system, disconnect the
negative (±) terminal cable from the battery.
HINT: Any diagnostic trouble code retained by the
computer will be erased when the battery terminal is
removed.
Therefore, if necessary, read the diagnosis before
removing the terminal.
CAUTION: Work must be started after 90 seconds from
the time the ignition switch is turned to the 'LOCK'
position and the negative (±) terminal cable is discon±
nected from the battery.
2. Do not smoke or work near an open flame when
working on the fuel system.
3. Keep gasoline away from rubber or leather parts.
3. IN EVENT OF ENGINE MISFIRE, FOLLOWING
PRECAUTIONS SHOULD BE TAKEN
(a) Check proper connection of battery terminals, etc.
(b) Handle high±tension cords carefully.
(c) After repair work, check that the ignition coil termi±
nals and all other ignition system lines are reconne±
cted securely.
(d) When cleaning the engine compartment, be especially
careful to protect the electrical system from water.
4. PRECAUTIONS WHEN HANDLING OXYGEN
SENSOR
(a) Do not allow oxygen sensor to drop or hit against an
object.
(b) Do not allow the sensor to come into contact with
water.
MAINTENANCE PRECAUTIONS

ELECTRONIC CONTROL SYSTEM
1. Before removing MFI/SFI wiring connectors, termi±
nals, etc., first disconnect the power by either turning
the ignition switch OFF or disconnecting the battery
terminals.
HINT: Always check the diagnostic trouble code
before disconnecting the negative (±) terminal cable
from the battery.
2. When installing the battery, be especially careful not
to incorrectly connect the positive (+) and negative
(±) cables.
3. Do not permit parts to receive a severe impact during
removal or installation. Handle all MFI/SFI parts care±
fully, especially the ECM.
4. Do not be careless during troubleshooting as there are
numerous transistor circuits and even slight terminal
contact can further troubles.
5. Do not open the ECM cover.
6. When inspecting during rainy weather, take care to
prevent entry of water. Also, when washing the
engine compartment, prevent water from getting on
the MFI/SFI parts and wiring connectors.
7. Parts should be replaced as an assembly.
AIR INDUCTION SYSTEM
1. Separation of the engine oil dipstick, oil filler cap, PCV
hose, etc. may cause the engine to run out of tune.
2. Disconnection, looseness or cracks in the parts of the
air induction system between the throttle body and
cylinder head will allow air suction and cause the
engine to run out of tune.
IF VEHICLE IS EQUIPPED WITH MOBILE
RADIO SYSTEM (HAM, CB, ETC.)
If the vehicle is equipped with a mobile communica±
tion system, refer to the precaution in the IN section.

RADIATOR
The radiator performs the function of cooling the coolant which has passed through the water
jacket and become 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 to 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 behind the radiator to assist the flow of air through the radiator. The
fan operates when the engine coolant temperature becomes high in order to prevent it from be-
coming 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 engine coolant temperature 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 sys-
tem exceeds the limit (coolant temperature: 110±120°C (230±248°F), pressure; 58.8103.0 kpa
(0.6±1.05 kgf/cm
2, 8.5±14.9 psi). The vacuum valve opens to alleviate the vacuum which develops
in the cooling system after the engine is stopped and the engine coolant temperature drops. The
valve'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 from the cooling system 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 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 bypass valve and is mounted in the water inlet housing. The
thermostat includes a type of automatic valve operated by fluctuations in the engine coolant
temperature. This valve closes when the engine 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 engine coolant temperature has risen, allowing the circulation 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 allows 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).

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 engine coolant should be free from oil.
If excessively dirty, replace the engine coolant.
3. REPLACE ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION: To avoid the danger of being burned, do not
remove It while the engine and radiator are still hot, as
fluid and steam can be blown out under pressure.
(b) Drain the engine coolant from the radiator drain cock
and engine drain plug. (Engine drain plug at the right
rear of cylinder block.)
(c) Close the drain cock and plug.
Torque (Engine drain plug):
13 N±m (130 kgf±cm, 9 ft±lbf)
(d) Slowly fill the system with coolant.
Use a good brand of ethylene±glycol base
coolant and mix it according to the
manufacturer 's directions.
Using engine coolant which includes more than
5096 ethylene±glycol (but not more than 7096) is
recommended.
NOTICE:
wDo not use a alcohol type coolant.
wThe engine coolant should be mixed with demineral±
ized water or distilled water.
Capacity (w/ Heater):
8.3 liters (6.7 US qts, 5.5 Imp.qts)
(a) Reinstall the radiator cap.
(f) Warm up the engine and check for leaks.
(g) Recheck the engine coolant level and refill as neces±
sary.
COOLANT CHECK AND
REPLACEMENT
1. CHECK ENGINE COOLANT LEVEL AT RESERVOIR
TANK
The engine coolant level should be between the
ºLOWº and ªFULLº lines.
If low, check for leaks and add engine coolant up to
the ªFULLº line.
