The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant level at least once a year, at the
beginning of the winter season and
before traveling to a colder climate.Checking the Engine Coolant
Level
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses. The coolant level should be filled
between the F and the L marks on the
side of the coolant reservoir when the
engine is cool.
If the coolant level is low, add enough
distilled (deionized) water to bring the
level to the F mark, but do not overfill. If
frequent additions are required, we rec-
ommend that you see an authorized
HYUNDAI dealer for a cooling system
inspection.
Recommended engine coolant
When adding coolant, use only deion-
ized water, distilled water or soft water
for your vehicle and never mix hard
water in the coolant filled at the factory.
An improper coolant mixture can result in severe malfunction or engine dam-
age.
The engine in your vehicle has alu- minum engine parts and must be pro-
tected by an ethylene-glycol with phos-
phate based coolant to prevent corro-
sion and freezing.
Do not use alcohol or methanol coolant or mix them with the specified coolant.
Do not use a solution that contains more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.OAD076125
