OWNER INSPECTIONS AND SERVICES
WHLE OPERATING THE VEHICLE
Horn Operation
Blow the horn occasionally tomake sure it works. Check
all the button locations.
Brake System Operation
Be alert for abnormal sounds, increased brake pedal trav-
el or repeated pulling to one side when braking. Also, if the
brake warning light goes on, or flashes, something may be
wrong with part of the brake system.
Exhaust System Operation
Be alert to any changes in the sound of the system or the
smell of the fumes. These are signs that the system may
be leaking or overheating. Have the system inspected and
repaired immediately.
Tires,Wheels and Alignment Operation
Be alert to any vibration of the steering wheel or the seats
at normal highway speeds. This may mean a wheel needs
to be balanced. Also, a pull right or left on a straight, level
road may show the need for a tire pressure adjustment or
a wheel alignment.
Steering System Operation
Be alert to changes in the steering action. An inspection
is needed when the steering wheel is hard to turn or has
too much free play, or if unusual sounds are noticed when
turning or parking.
Headlight Aim
Take note of the light pattern occasionally. Adjust the
headlights if the beams seem improperly aimed.
AT EACH FUEL FILL
A fluid loss in any (except windshield washer) system may
indicate a problem. Have the system inspected and re-
paired immediately.
Engine Oil Level
Check the oil level and add oil if necessary. The best time
to check the engine oil level is when the oil is warm.
1. After stopping the engine, wait a few minutes for
the oil to drain back to the oil pan.
2. Pull out the oil level indicator (dip stick).
3. Wipe it clean, and push the oil level indicator back
down all the way.
4. Pull out the oil level indicator and look at the oil lev-
el on it.
5. Add oil, if needed, to keep the oil level above the
MIN line and within the area labeled ”Operating
Range.” Avoid overfilling the engine, since this may
cause engine damage.
6. Push the indicator all the way back down into the
engine after taking the reading.If you check the oil level when the oil is cold, do not run the
engine first. The cold oil will not drain back to the pan fast
enough to give a true oil level reading.
Engine Coolant Level and Condition
Check the coolant level in the coolant reservoir tank and
add coolant if necessary. Inspect the coolant. Replace
dirty or rusty coolant.
Windshield Washer Fluid Level
Check the washer fluid level in the reservoir. Add fluid if
necessary.
AT LEAST MONTHLY
Tire And Wheel Inspection and Pressure
Check
Check the tires for abnormal wear or damage. Also check
for damaged wheels. Check the tire pressure when the
tires are cold (check the spare also, unless it is a stow-
away). Maintain the recommended pressures that are on
the tire placard that is in the glove box.
Light Operation
Check the operation of the license plate light, the head-
lights (including the high beams), the parking lights, the
fog lights, the taillight, the brake lights, the turn signals, the
backup lights and the hazard warning flasher.
Fluid Leak Check
Periodically inspect the surface beneath the vehicle for
water, oil, fuel or other fluids, after the vehicle has been
parked for a while. Water dripping from the air conditioning
system after use is normal. If you notice fuel leaks or
fumes, find the cause and correct it at once.
AT LEAST TWICE A YEAR
Power Steering System Reservoir Level
Check the power steering fluid level. Keep the power
steering fluid at the proper level. Refer to Section 6A, Pow-
er Steering System.
Brake Master Cylinder Reservoir Level
Check the fluid and keep it at the proper level. A low fluid
level can indicate worn disc brake pads which may need
to be serviced. Check the breather hole in the reservoir
cover to be free from dirt and check for an open passage.
Clutch Pedal Free Travel
Check clutch pedal free travel and adjust as necessary.
Measure the distance from the center of the clutch pedal
to the outer edge of the steering wheel with the clutch ped-
al not depressed. Then measure the distance from the
center of the clutch pedal to the outer edge of the steering
wheel with the clutch pedal fully depressed. The difference
between the two values must be greater than 130 mm
(5.19 inches).
Weather–Strip Lubrication
Apply a thin film silicone grease using a clean cloth.

GENERAL DESCRIPTION
AND SYSTEM OPERATION
GENERAL DESCRIPTION
The cooling system maintains the engine temperature at
an efficient level during all engine operating conditions.
When the engine is cold, the cooling system cools the en-
gine slowly or not at all. This slow cooling of the engine al-
lows the engine to warm up quickly.
The cooling system includes a radiator and recovery sub-
system, cooling fans, a thermostat and housing, a coolant
pump, and a coolant pump drive belt. The timing belt
drives the coolant pump.
All components must function properly in order for the
cooling system to operate. The coolant pump draws the
coolant from the radiator. The coolant then circulates
through water jackets in the engine block, the intake man-
ifold, and the cylinder head. When the coolant reaches the
operating temperature of the thermostat, the thermostat
opens. The coolant then goes back to the radiator where
it cools.
This system directs some coolant through the hoses to the
heater core. This provides for heating and defrosting. The
surge tank is connected to the radiator to recover the cool-
ant displaced by expansion from the high temperatures.
The surge tank maintains the correct coolant level.
The cooling system for this vehicle has no radiator cap or
filler neck. The coolant is added to the cooling system
through the surge tank.
RADIATOR
This vehicle has a lightweight tube–and–fin aluminum ra-
diator. Plastic tanks are mounted on the right and the left
sides of the radiator core.
On vehicles equipped with automatic transaxles, the
transaxle fluid cooler lines run through the left radiator
tank. A radiator drain cock is on this radiator.
To drain the cooling system, open the drain cock.
SURGE TANK
The surge tank is a transparent plastic reservoir, similar to
the windshield washer reservoir.
The surge tank is connected to the radiator by a hose and
to the engine cooling system by another hose. As the ve-
hicle is driven, the engine coolant heats and expands. The
portion of the engine coolant displaced by this expansion
flows from the radiator and the engine into the surge tank.
The air trapped in the radiator and the engine is degassed
into the surge tank.When the engine stops, the engine coolant cools and con-
tracts. The displaced engine coolant is then drawn back
into the radiator and the engine. This keeps the radiator
filled with the coolant to the desired level at all times and
increases the cooling efficiency.
Maintain the coolant level between the MIN and the MAX
marks on the surge tank when the system is cold.
WATER PUMP
The belt–driven centrifugal water pump consists of an im-
peller, a drive shaft, and a belt pulley. The water pump is
mounted on the front of the transverse–mounted engine,
and is driven by the timing belt.
The impeller is supported by a completely sealed bearing.
The water pump is serviced as an assembly and, there-
fore, cannot be disassembled.
THERMOSTAT
A wax pellet–type thermostat controls the flow of the en-
gine coolant through the engine cooling system. The ther-
mostat is mounted in the thermostat housing to the front
of the cylinder head.
The thermostat stops the flow of the engine coolant from
the engine to the radiator in order to provide faster warm–
up, and to regulate the coolant temperature. The thermo-
stat remains closed while the engine coolant is cold, pre-
venting circulation of the engine coolant through the
radiator. At this point, the engine coolant is allowed to cir-
culate only throughout the heater core to warm it quickly
and evenly.
As the engine warms, the thermostat opens. This allows
the engine coolant to flow through the radiator, where the
heat is dissipated through the radiator. This opening and
closing of the thermostat permits enough engine coolant
to enter the radiator to keep the engine within proper en-
gine temperature operating limits.
The wax pellet in the thermostat is hermetically sealed in
a metal case. The wax element of the thermostat expands
when it is heated and contracts when it is cooled.
As the vehicle is driven and the engine warms, the engine
coolant temperature increases. When the engine coolant
reaches a specified temperature, the wax pellet element
in the thermostat expands and exerts pressure against the
metal case, forcing the valve open. This allows the engine
coolant to flow through the engine cooling system and cool
the engine.
As the wax pellet cools, the contraction allows a spring to
close the valve.
The thermostat begins to open at 87°C (189°F) and is fully
open at 102°C (216°F). The thermostat closes at 86°C
(187°F).
