Recommended Engine Coolant
Use a high quality ethylene-glycol coolant
in a 50/50 mix with water. The engine
coolant should be compatible with alumi-
num 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 con-
centration when adding or replacing the
engine coolant, refer to the following table.

To Check the Coolant Level
The coolant level can be seen on the side
of the plastic coolant reservoir. The level of
the coolant should be between the "L" and
"F" lines on the reservoir when the engine
Water
is warm with it at idle . If the level is below
the "L" mark, add engine coolant to bring
65%
it up to "F". If the level is low, inspect for
60%
coolant leaks and recheck the fluid level
frequently. If the level drops again, visit
50%
your Hyundai dealer for an inspection and
40%
diagnosis of the reason.
DO-IT-YOURSELF MAINTENANCE
!
CAUTION:
o Engine coolant can damage the finish
of your car. If you spill engine coolant
on the car, wash it off thoroughly with
clean water.
o The engine in your vehicle has alumi-
num engine parts and must be pro-
tected by an ethylene-glycol base
coolant to prevent corrosion and freez-
ing.
Do not use hard water. Hard water can
cause engine damage from corro-
G050C01TG
sion, overheating or freezing.
!
WARNING:
The cooling fan is controlled by engine
coolant temperature and may some-
times operate 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 engine coolant
temperature decreases, the fan will au-
tomatically shut off. This is a normal
condition.
