Maintenance
Recommended engine coolant
(Continued)
•
When adding coolant, use only deion-
ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
•
Even if the engine is not operat-
ing, do not remove the radiator
cap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.
•
The engine in your vehicle has alu-
minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-
ing.
WARNING
The electric motor (cool-
ing fan) is controlled by
engine coolant tempera-
ture, refrigerant pres-
sure and vehicle speed.
It may sometimes operate even
when the engine is not running.
Use extreme caution when working
near the blades of the cooling fan
so that you are not injured by a
rotating fan blades. As the engine
coolant temperature decreases, the
electric motor will automatically
shut off.This is a normal condition.

DO NOT USE alcohol or methanol
coolant or mix them with the specified
coolant.
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
Do not use a solution that contains
more than 60% antifreeze or less than
35% antifreeze, which would reduce

the effectiveness of the solution.
For mixture percentage, refer to the fol-
lowing table.
If the coolant level is low, add enough
distilled (deionized) water. Bring the level
to F (MAX), but do not overfill. If frequent
coolant refill is required, see an author-
ized HYUNDAI dealer for a cooling sys-
tem inspection.
