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.
5. Start the engine, top off the radiator with
water and then add coolant to the reservoir
until the level is between "L" and "F".
6. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.G060A02Y-AATSPARK PLUGS
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.
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.

Replacing the Spark PlugsThe spark plugs should be changed at the
intervals specified in the vehicle maintenance
schedule in Section 5 or whenever engine
performance indicates they should be changed.
Symptoms that suggest poor spark plug perfor-
mance include engine misfiring under load, loss
of fuel economy, poor acceleration, etc. When
spark plugs are replaced, always use spark
plugs recommended by Hyundai. The use of
other spark plugs can result in loss of perfor-
mance, radio interference or engine damage.
NOTE:When replacing the spark plugs, always use
the genuine parts recommended.
