G050B01A-AATRecommended Engine CoolantUse 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.
G050C01NF-GATTo Check the Coolant LevelThe 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 warm with it at idle . If the level is below
the "L" mark, add engine coolant to bring
it up to "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 inspection and
diagnosis of the reason.
G050C01NFG050D01NF-GAT
To Change the Engine CoolantThe engine coolant should be changed at
those intervals specified in the vehicle
maintenance schedule in Section 5.
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
protected 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-
sion, overheating or freezing.
