Checking The Engine Coolant Level - Hyundai i30 Owner's Manual

E E N N G G I I N N E E C C O O O O L L A A N N T T
The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant concentration level at least
once a year, at the beginning of the
winter season, and before traveling
to a colder climate.
NOTICE
• When the engine overheats from
low engine coolant, suddenly
adding engine coolant may cause
cracks in the engine. To prevent
damage, add engine coolant
slowly in small quantities.
• Do not drive with no engine
coolant. It may cause water pump
failure and engine seizure, etc.
Checking the engine coolant
level
■ Type A
■ Type B
■ Type C
Check the condition and connections
of all cooling system hoses and
OPDE076068
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between MAX and MIN (or F (Full)
and L (Low)) 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 MAX, (or F (Full)) but do not
overfill.

If frequent additions are required, we
recommend that the system be
inspected by an authorized HYUNDAI
dealer.
