To Check the Coolant Level

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 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 fre-

quently. If the level drops again, visit your
Hyundai dealer for an inspection and diagnosis
of the reason.

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
G050C01Y
the manufacturer's directions on the engine
coolant container, add the appropriate quan-
tity of coolant to the radiator. Now fill the
radiator with clean demineralized or distilled
water. Continue to add clean demineralized
or distilled water in small quantities until the
fluid level stays up in the radiator neck.
4. Start the engine, top off the radiator with
water and then add coolant to the reservoir
until the level is between "LOW" and "FULL".
5. 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 oper-
ate even when the engine is not running.
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 en-
gine coolant temperature decreases, the fan
will automatically shut off. This is a normal
condition.

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 iden-
