Engine Coolant; Checking The Coolant Level - Hyundai i20 Owner's Manual

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 level at least once a year, at the
beginning of the winter season, and
before traveling to a colder climate.
NOTICE
• Do not drive with no engine coolant.
It may cause water pump failure and
engine seizure, etc.
• 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.

Checking the coolant level

Petrol Engine (1.0 T-GDi) Petrol Engine (1.0 T-GDi)
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 F (Full) and L (Low) marked 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 (Full), but do
not overfill. If frequent additions are
required, we recommend that the
system be inspected by an authorized
HYUNDAI dealer.
