Hyundai i-30: Maintenance / Engine coolant
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 travelling
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
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 a HYUNDAI authorised
repairer.

■ Type A

■ Type B

■ Type C
WARNING

Never remove the
coolant cap/radiator
cap or the drain plug
whilst the engine and
radiator are hot. Hot
coolant and steam may blow
out under pressure, causing
serious injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when removing
the coolant cap/radiator
cap. Wrap a thick towel around
it, and turn it counterclockwise
slowly to the first stop. Step
back whilst the pressure is
released from the cooling system.
When you are sure all the
pressure has been released,
press down on the cap, using a
thick towel, and continue turning
counterclockwise to remove
it.
WARNING

The electric motor for
the cooling fan may
continue to operate
or start up when the
engine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan blades
of the cooling fan.
The electric motor for the cooling fan
is controlled by engine coolant temperature,
refrigerant pressure and
vehicle speed. As the engine coolant
temperature decreases, the electric
motor will automatically shut off. This
is a normal condition. If your vehicle
is equipped with GDI, the electric
motor for the cooling fan may begin
to operate at any time and continue
to operate until you disconnect the
negative battery cable.
Recommended engine coolant
- When adding coolant, use only distilled
(deionized) water for your
vehicle and never mix hard water in
the coolant filled at the factory. An
incorrect coolant mixture can result
in serious malfunction or engine
damage.
- The engine in your vehicle has aluminium
engine parts and must be
protected by an ethylene-glycol
with phosphate based coolant to
prevent 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
following table.

Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of
-35°C (-31°F) and higher.
Changing the engine coolant
We recommend that coolant be
changed by a HYUNDAI authorised
repairer according to the
Maintenance schedule.
NOTICE
To prevent damage to engine parts,
put a thick towel around the engine
coolant cap or radiator cap before
refilling the coolant to prevent the
coolant from overflowing into
engine parts, such as the alternator.
We recommend that the engine oil
and filter be replaced by a HYUNDAI
authorised repairer.
WARNING
Used engine oil may cause irritation
or cancer of the skin if
left in contact with the skin for
prolonged periods of time...
Checking the brake/clutch
fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir...
