Type B
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 F and 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. Bring the level
to F, but do not overfill. If frequent addi-
tions are required, see an authorized
HYUNDAI dealer for a cooling system
inspection.

Recommended engine coolant
• 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.
• The engine in your vehicle has aluminum
engine parts and must be protected by
an ethylene-glycol-based coolant to pre-
vent corrosion 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.
For mixture percentage, refer to the fol-
lowing table.
