Coolant; Checking The Engine Coolant Level - Kia Sorento 2022 Manual

Maintenance

Coolant

The high-pressure cooling system
has a reservoir filled with year
round antifreeze coolant. The reser-
voir 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 travelling to a colder cli-
mate.

Checking the engine coolant level

When adding coolant, use only
deionised water, distilled water or
soft water for your vehicle and
never mix hard water in the coolant
filled at the factory.
An incorrect coolant mixture can
result in severe malfunction or
engine/hybrid system damage.
The engine in your vehicle has
aluminium engine parts and must
be protected by an phosphate-
based ethylene glycol 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 con-
tains more than 60% antifreeze
or less than 35% antifreeze,
which would reduce the effective-
ness of the solution.
Check the condition and connec-
tions of all cooling system hoses
and heater hoses. Replace any
swollen or deteriorated hoses.
The coolant level should be filled
between MAX and MIN marks on
the side of the coolant reservoir
when the engine is cool. If the
coolant level is low, add enough
specified coolant to provide pro-
tection against freezing and cor-
rosion. Bring the level to MAX, but
do not overfill. If frequent addi-
tions are required, have the sys-
tem inspected by a professional
workshop. Kia recommends to
visit an authorised Kia dealer/ser-
vice partner.

WARNING
Make sure the engine coolant reser-
voir cap is properly closed after refill
or coolant.
Otherwise the engine could be over-
heated whilst driving.
