僅 Changing The Coolant - Kia Sportage 2023 Owner's Manual

Maintenance
Recommended engine coolant
僅 When adding coolant, use only deion-
ized water or soft water for your vehi-
cle and never mix hard water in the
coolant filled at the factory. An
improper coolant mixture can result in
serious malfunction or engine dam-
age.
僅 The engine in your vehicle has alumi-
num engine parts and must be pro-
tected by an ethylene-glycol with
phosphate based coolant to prevent
corrosion and freezing.
僅 DO NOT USE alcohol or methanol
coolant or mix them with the specified
coolant.
僅 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.

prevent the coolant from overflowing
into engine parts such as the alternator.
