If the coolant level is low, add enough specified
coolant to provide protection against freezing and
corrosion and to bring the level to F in the coolant
reservoir. Do not overfill. If frequent additions are
required, see an Authorized Kia Dealer for a cooling
system inspection.
Changing Coolant
Change coolant according to the Scheduled
Maintenance.
• Use only soft (de-mineralized) water in the coolant
mixture.
• The engine in your vehicle has aluminum engine
parts and must be protected by an ethylene glycol-
based coolant to prevent corrosion and freezing.
• DO NOT USE alcohol or methanol coolant and do
not 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 percentages, refer to the following table.
