THE ENGINE COOLANT

!
WARNING:
Do not remove the radiator cap when
the engine is hot. When the engine is
hot, the engine coolant is under pres-
sure and may erupt through the open-
ing if the cap is removed. You could
be seriously burned if you do not
observe this precaution. Do not re-
move the radiator cap until the radia-
tor is cool to the touch.

Recommended Engine Coolant
Use a high quality ethylene-glycol cool-
ant 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 con-
centration and type of engine coolant
to prevent freezing and corrosion.
Never allow the concentration of anti-
freeze 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
HHR4010
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 is cold. If the
level is below the "L" mark, add engine
coolant to bring it up between "L" and
"F". If the level is low, inspect for
coolant leaks and recheck the fluid
level frequently. If the level drops again,
visit your Hyundai dealer for an inspec-
tion and diagnosis of the reason.
