WARNING:
Do not remove the radiator cap when the
engine is hot. When the engine is hot, the
engine coolant is under pressure and may
erupt through the opening if the cap is
removed. You could be seriously burned if
you do not observe this precaution. Do not
remove the radiator cap until the radiator is
cool to the touch.

Recommended Engine Coolant

Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant should
be compatible with aluminum 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 concentration 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 cool-
ant should be between the "L" and "F" lines on
Water
the reservoir when the engine is cool. If the level
is below the "L" mark, add engine coolant to
65%
bring it up between "L" and "F". If the level is low,
60%
inspect for coolant leaks and recheck the fluid
50%
level frequently. If the level drops again, visit
your Hyundai dealer for an inspection and
40%
diagnosis of the reason.
