conditions, more frequent oil and filter changes
are required.

Fuel FilterA clogged filter can limit the speed at which the
vehicle may be driven, damage the emission
system and cause hard starting. If an exces-
sive amount of foreign matter accumulates in
the fuel tank, the filter may require replace-
ment more frequently.
After installing a new filter, run the engine for
several minutes, and check for leaks at the
connections. Fuel filters should be installed by
trained technicians.

Inspect the surface of hoses for evidence of
heat and/or mechanical damage. Hard and
brittle rubber, cracking, tears, cuts, abra-
sions, and excessive swelling indicate dete-
rioration. Particular attention should be paid to
examine those hose surfaces nearest to high
heat sources, such as the exhaust manifold.
Inspect the hose routing to assure that the
hoses do not come in contact with any heat
source, sharp edges or moving component
which might cause heat damage or mechani-
cal wear. Inspect all hose connections, such
as clamps and couplings, to make sure they
are secure, and that no leaks are present.
Hoses should be replaced immediately if there
is any evidence of deterioration or damage.

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

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 counterclockwise.
Now fill the radiator with clean demineral-
ized 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.

1. Using a wrench of the correct size, loosen
the oil filler plug by turning it counterclock-
wise and remove it with your fingers.
2. Use your finger or suitable tool to feel inside
the hole. The oil level should be at its bottom
edge. If it is not, check for leaks before
adding oil. To refill the transaxle or bring the
oil level up,add oil slowly until it reaches the
proper level. Do not overfill.
