Recommended coolant
ś
When adding coolant, use only
deionized water, distilled water, or soft
water for your vehicle and never mix
hard water in the coolant filled at the
factory.
ś
An incorrect coolant mixture may
result in severe malfunction or engine
damage.
ś
The engine in your vehicle has
aluminum engine parts and must be
protected by an phosphate-based
ethylene glycol coolant to prevent
corrosion and freezing.
ś
Do not use alcohol or methanol
coolant or mix them with the specified
coolant.
ś
Do not use a solution that contains
more than 60% antifreeze or less than
35% antifreeze, which could reduce
the effectiveness of the solution.
For mixing percentage, refer to the
following table:

Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together because it is the
same quantity for each.
Changing Coolant
Have the coolant changed by an
authorized HYUNDAI dealer according to
the Maintenance Schedule.
NOTICE
To prevent damage to engine parts, put
a thick towel around the engine coolant
cap before refilling the coolant to prevent
the coolant from overflowing into engine
parts, such as the alternator.
