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 bypushing down and turning counterclockwise. Now fill the radiator with clean demineral- ized or distilled water. Continue to add cleandemineralized or distilled water in small quan-tities until the fluid level stays up in theradiator neck.SSA6060A

REPLACING THE SPARK PLUGS
The spark plugs should be changed at the
intervals specified in the vehicle maintenance schedule in Section 5 or whenever engine per-formance indicates they should be changed.Symptoms that suggest poor spark plug perfor-mance include engine misfiring under load, lossof fuel economy, poor acceleration, etc. Whenspark plugs are replaced, always use sparkplugs recommended by Hyundai. The use ofother spark plugs can result in loss of perfor-mance, radio interference or engine damage.
NOTE: When replacing the spark plug, always use
the genuine parts recommended.

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 fullyclosed and not leaking.
WARNING: The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper- ate even when the engine is not running.Use extreme caution when working near theblades of the cooling fan so that you are notinjured by a rotating fan blade. As the en-gine coolant temperature decreases, the fanwill automatically shut off. This is a normalcondition.

6-8 NOTE: Spark plugs should be tightened firmly. Over- tightening can damage the threads in thealuminum cylinder head. Also, leaving them
too loose can cause the spark plug to getvery hot and possibly result in damage tothe engine.
6. Replace the cable by pushing the insulated connector directly down onto the electrode.Check to be sure it has snapped into placeand can't fall off.

You will find it easier to change spark plugs if
the engine is cold. Always change one spark
plug at a time. This helps avoid getting the wiresmixed up.
1. Using a clean cloth, remove any dirt that has accumulated around the base of the spark plug so it cannot fall into the cylinder whenthe spark plug is removed. WARNING: It is recommended that the engine be cool
or cold when changing the spark plugs. If the engine is hot, you could burn yourselfon the insulated connector, the spark plugor the engine itself.
3. When preparing to remove the old spark plug, guide the socket down over the spark plug, being careful not to damage the ce-ramic insulator.
4. To remove the old spark plug, turn the wrench handle in a counterclockwise direc-tion.
5. To install the new spark plug, guide the socket down over the spark plug, beingcareful not to damage the ceramic insulator.

Recommended Spark Plugs:
2. To remove the spark plug cable, pull straight
up on the insulated connector, not the cable. Pulling on the cable may damage the carboncore conductor.

POWER STEERING FLUID LEVEL
The power steering fluid level should be checked
regularly.
To check the power steering fluid level, be sure
the ignition is "OFF", then check to make cer- tain that the power steering fluid level is be-tween the "MAX" and "MIN" level markings onthe 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 -20°C). If the noise stops dur-ing warm up, there is no abnormal functionin the system. This is due to a power steer-ing fluid characteristic in extremely coldconditions.
G230A01X
The fluid in the battery contains a strong solu-
tion of sulfuric acid, which is poisonous and highly corrosive. Be careful not to spill it onyourself or the car. If you do spill battery fluid onyourself, immediately do the following:
o If battery fluid is on your skin, flush the affected areas with water for at least 15 minutes and then seek medical assistance.
o If battery fluid is in your eyes, rinse out your eyes with water and get medical assistanceas soon as possible. While you are beingdriven to get medical assistance, continueto rinse your eyes by using a sponge or softcloth saturated with water.
o If you swallow battery fluid, drink a large quantity of water or milk followed by milk ofmagnesia, eat a raw egg or drink vegetableoil. Get medical assistance as soon aspossible.
While batteries are being charged (either by abattery charger or by the vehicle's alternator),they produce explosive gases. Always observethese warnings to prevent injuries from occur-ring:
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. G210B01A-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 household bak-ing soda and warm water. After the batteryterminals are dry, cover them with a light coat-ing of grease.

CHECKING ELECTRIC COOLING
FANS
WARNING: The radiator fan is controlled by engine cool- ant temperature and may sometimes operateeven when the engine is not running. Use extreme caution when working near the blades of the cooling fan, so that you are not injuredby a rotating fan blade. As the coolant tem-perature decreases the fan will automaticallyshut off. This is a normal condition.
G220B01A-AAT
Checking Engine Cooling Fan The engine cooling fan should come on auto-
matically if the engine coolant temperature ishigh.
G220C01A-AAT
Checking Condenser Cooling Fan The condenser cooling fan should come on
automatically whenever the air conditioning isin operation.
