CHECKING AND CHANGING THE
ENGINE COOLANT
!
G050A01A-AAT
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
removed. You could be seriously burned if
you do not observe this precaution. Do not
remove the radiator cap until the radiator is
cool to the touch. Be sure that the mounting surface on the
engine is clean and that the old gasket is
removed completely. Lubricate the new
gasket on the filter with clean engine oil
before installation.
7. Refill the crankcase with the recommended
engine oil. Refer to the specification in chap-
ter 9 for engine oil capacity.
8. Start the engine and check to be sure no oil
is leaking from the drain plug or oil filter.
9. Shut off the engine and recheck the oil level.
NOTE:Always dispose of used engine oil in an
environmentally acceptable manner. It is
suggested that it be placed in a sealed
container and taken to a service station for
reclamation. Do not pour the oil on the
ground or put it in with the household
trash.
PROPOSITION 65 WARNING:Used engine oil may cause irritation or
cancer of the skin if left in contact with the
skin for prolonged periods of time. Used
engine oil contains chemicals that have
caused cancer in laboratory animals. Al-
ways protect your skin by washing your
hands thoroughly with soap and warm
water as soon as possible after handling
used oil.

Recommended 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.
Additional corrosion inhibitors or additives should
not be used. The cooling system must be
maintained with the correct concentration and
type of engine coolant to prevent freezing and
corrosion. Never allow the concentration of
antifreeze to exceed the 60% level or go below
the 35% level, or damage to the cooling system
may result. For proper concentration when
adding or replacing the engine coolant, refer to
the following table.

To Check the Coolant Level
G050D02A-AAT
To Change the Engine Coolant
The engine coolant should be changed at those
intervals specified in the vehicle maintenance
schedule 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 park-
ing 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 counterclock-
wise.
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.
G050D03E
The coolant level can be seen on the side of the
plastic coolant reservoir. The level of the cool-
ant should be between the "LOW" and "FULL"
lines on the reservoir when the engine is cold.
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.

5. Start the engine, top off the radiator with
water and then add 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
coolant temperature and may sometimes
operate even when the engine is not run-
ning. Use extreme caution when working
near the blades of the coolant fan so that
you are not injured by a rotating fan blade.
As the engine coolant temperature de-
creases, the fan will automatically shut off.
This is a normal condition.

SPARK PLUGS
G060A01GK-AAT
Your engine was originally equipped with plati-
num-tipped spark plugs. Platinum-tipped spark
plugs will last longer than conventional type
spark plugs and can be identified by blue lines
on the ceramic shell.
NOTE:Do not clean or regap platinum-tipped spark
plugs.

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 should not be operated if
the washer reservoir is empty. This can
damage the washer fluid pump.

The washer fluid reservoir supplies fluid to the
windshield washer system.
A good quality washer fluid should be used to fill
the washer reservoir. The fluid level should be
checked more frequently during inclement
weather or whenever the washer system is in
more frequent use.
The capacity of the washer reservoir is 3.2 U.S.
quarts (3.0 Liters).

CHECKING THE BRAKES
G120A01A-AAT
CAUTION:Because brakes are essential to the safe
operation of the car, it is suggested that
they be checked and inspected by your
Hyundai dealer. The brakes should be
checked and inspected for wear at those
intervals specified in the vehicle mainte-
nance schedule in Section 5.

Checking the Brake Fluid Level
WARNING:
Use caution when handling brake fluid. It
can damage your vision if it gets into your
eyes. It will also damage your vehicle’s
paint if spilled on it and not removed imme-
diately.
G120D01A-AATTo Check the Fluid Level
The fluid level in the brake fluid reservoir should
be checked periodically. The level should be
between the "MIN" and "MAX" marks on the side
of the reservoir. If the level is at or below the
"MIN" mark, carefully add fluid to bring it up to
"MAX". Do not overfill.
G120C02A-AAT
Recommended Brake Fluid
Use only hydraulic brake fluid conforming to
DOT 3 or DOT 4 specifications in your braking
system. Follow the instructions printed on the
container.

While batteries are being charged (either by a
battery charger or by the vehicle’s generator),
they produce explosive gases. Always ob-
serve these warnings to prevent injuries from
occurring:
o Charge batteries only in a well ventilated
area.
o Do not permit flames, sparks or smoking in
the area.
o Keep children away from the area.
!
G210B02A-AAT
Checking the Battery
Keep the battery clean. Any evidence of corro-
sion around the battery posts or terminals
should be removed using a solution of house-
hold baking soda and warm water. After the
battery terminals are dry, cover them with a light
coating of grease.
PROPOSITION 65 WARNING:Battery posts, terminals, and related acces-
sories contain lead and lead compounds,
chemicals known to the state of California
to cause cancer and reproductive harm.
Batteries also contain other chemicals
known to the state of California to cause
cancer. Wash hands after handling.

24POWER STEERING FLUID LEVEL
G230A03A-AAT
The power steering fluid level should be checked
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 condi-
tions (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 characteristic in extremely cold condi-
tions.

FOR MORE INFORMATION ABOUT
YOUR HYUNDAI
If you desire additional information about main-
taining and servicing your Hyundai, you may
purchase a factory Shop Manual at your Hyundai
dealer's parts department. This is the same
manual used by dealership technicians and
while it is highly technical it can be useful in
obtaining a better understanding of your car and
how it works.
G240A01A-AATPOWER STEERING HOSES
It is suggested that you check the power steer-
ing hose connections for fluid leakage at regular
intervals. The power steering hoses should be
replaced if there is severe surface cracking,
scuffing or worn spots. Deterioration of the hose
could cause premature failure. Recommended Fluid
Use PSF-3 type fluid
NOTE:Do not start the engine when the power
steering oil reservoir is empty.
G220C01A-AATChecking Condenser Cooling Fan
The condenser coolant fan should come on
automatically whenever the air conditioning is in
operation.

The engine cooling fan should come on auto-
matically if the engine coolant temperature is
high.
