G050A01A-AATCHECKING AND CHANGING THE EN-
GINE COOLANTG050B01A-AATRecommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant should
be compatible with aluminum engine parts. Ad-
ditional corrosion inhibitors or additives should
not be used. The cooling system must be main-
tained with the correct concentration and type of
engine coolant to prevent freezing and corro-
sion.
Never allow the concentration of antifreeze to
exceed the 60% level or go below the 35% level
or damage to the coolant system may result. For
proper concentration when adding or replacing
the coolant, refer to the following table.
WARNING:Do not remove the radiator cap when the
engine is hot. When the engine is hot, the
engine coolant is under pressure and may
erupt through the opening if the cap is re-
moved. You could be seriously burned if you
do not observe this precaution. Do not re-
move the radiator cap until the radiator is
cool to the touch.

G050C01A-AATTo Check the Coolant Level
The coolant level can be seen on the side of the
plastic coolant reservoir. The level of the coolant
should be between the "LOW" and "FULL" lines
on the reservoir when the engine is cool. If the
level is below the "LOW" mark, add engine
coolant to bring it up between "LOW" and "FULL".
If the level is low, inspect for coolant leaks and
recheck the fluid level frequently. If the level
drops again, visit your Hyundai dealer for an
inspection and diagnosis of the reason.

G050D02A-AATTo Change the Coolant
The coolant should be changed at those inter-
vals specified in the vehicle maintenance sched-
ule in Section 5.
CAUTION:Engine coolant can damage the finish of
your car. If you spill engine coolant on the
car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the parking
brake and remove the radiator cap when
cool.
2. Be sure your drain receptacle is in place.
Open the drain cock on the radiator. Allow all
the engine coolant to drain from the cooling
system, then securely close the drain cock.
3. Check Section 9 for the capacity of the
cooling system in your car. Then, following
the manufacturer's directions on the engine
coolant container, add the appropriate quan-
tity of coolant to the radiator.
!
4. Turn the radiator cap counterclockwise with-
out pressing down on it, until it stops. This
relieves any pressure remaining in the cool-
ing system. And remove the radiator cap by
pushing down and turning counterclockwise.
Now fill the radiator with clean demineralized
or distilled water. Continue to add clean
demineralized or distilled water in small quan-
tities until the fluid level stays up in the
radiator neck.

G050D02A
5. Start the engine, top off the radiator with
water and then add engine coolant to the
reservoir until the level is between "LOW"
and "FULL".
6. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.
WARNING:The cooling fan is controlled by engine cool-
ant temperature and may sometimes operate
even when the engine is not running. Use
extreme caution when working near the
blades of the cooling fan so that you are not
injured by a rotating fan blade. As the engine
coolant temperature decreases, the fan will
automatically shut off. This is a normal con-
dition.

G090A01A-AATFILLING THE WASHER RESERVOIR
A good quality washer fluid should be used to fill
the washer reservoir. The fluid level should be
checked more frequently during bad weather or
whenever the washer system is in more fre-
quent use.
The capacity of the washer reservoir is 3.2 U.S.
quarts (3.0 Liters).
CAUTION:o Radiator anti-freeze (engine coolant)
should not be used in the washer system
because it will damage the car's finish.
o The washer lever should not be operated
if the washer reservoir is empty. This can
damage the washer fluid pump.

regularly. To check the power steering fluid
level, be sure the engine is "OFF", then check to
make certain that the power steering fluid level
is between the "MAX" and "MIN" level markings
on the fluid reservoir.
NOTE:Grinding noise from the power steering pump
may be heard immediately after the engine is
started in extremely cold conditions (below
-4°F). If the noise stops during warm up,
there is no abnormal function in the system.
It is due to a power steering fluid character-
istic in extremely cold conditions.

7- 2 EMISSION CONTROL SYSTEMS
H010C01S-AAT2. Evaporative Emission Control (In-
cluding ORVR: Onboard Refueling Va-
por Recovery) System
The Evaporative Emission Control System is
designed to prevent fuel vapors from escaping
into the atmosphere.
(The ORVR system is designed to allow the
vapors from the fuel tank to be loaded into a
canister while refueling at the gas station, pre-
venting the escape of fuel vapors into the atmo-
sphere.)
Canister
Fuel vapors generated inside the fuel tank are
absorbed and stored in the onboard canister.
When the engine is running, the fuel vapors
absorbed in the canister are drawn into the
induction system through the purge control so-
lenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is controlled by
the Engine Control Module (ECM); when the
engine coolant temperature is low during idling,
the PCSV closes so that evaporated fuel is not
taken into the engine. After the engine warms-
up during ordinary driving, the PCSV opens to
introduce evaporated fuel to the engine.
H010B01A-AAT
1. CRANKCASE EMISSION CONTROL
SYSTEM
The positive crankcase ventilation system is
employed to prevent air pollution caused by
blow-by gases being emitted from the crank-
case. This system supplies filtered fresh air to
the crankcase through the air intake hose. In-
side the crankcase, the fresh air mixes with
blow-by gases, then passes through the PCV
valve into the induction system.
H010A01A-AATEMISSION CONTROL SYSTEM
Your Hyundai is equipped with an emission
control system to meet all requirements of the
U.S. Environmental Protection Agency or Cali-
fornia Air Resources Board.
There are three emission control systems which
are as follows.
1) Crankcase Emission Control System
2) Evaporative Emission Control System
3) Exhaust Emission Control System
In order to ensure the proper function of the
emission control systems, it is recommended
that you have your car inspected and main-
tained by an authorized Hyundai dealer in ac-
cordance with the maintenance schedule in this
manual.
H010D01A-AAT3. EXHAUST EMISSION
CONTROL SYSTEM
The Exhaust Emission Control System is a
highly effective system which controls exhaust
emissions while maintaining good vehicle
performace.
H020A01A-AATCATALYTIC CONVERTER
All Hyundai vehicles are equipped with a mono-
lith type three-way catalytic converter to reduce
the carbon monoxide, hydrocarbons and nitro-
gen oxides contained in the exhaust gas. Ex-
haust gases passing through the catalytic con-
verter cause it to operate at a very high tem-
perature. The introduction of large amounts of
