2018 KIA STONIC cooling

ENGINE COOLANT
The high-pressure cooling system has
a reservoir filled with year round anti‐
freeze 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 be‐ fore traveling to a colder climate.
CAUTION
•When the engine overheats fromlow engine coolant, suddenly add‐ing engine coolant may causecracks in the engine. To preventdamage, add engine coolant slowlyin small quantities.
•Do not drive with no engine cool‐ant. It may cause water pump fail‐ure and engine seizure, etc.
Checking the coolant level
WARNING
Removing radiator cap
•Never attempt to remove the radi‐ator cap while the engine is oper‐ating or hot. Doing so might leadto cooling system and engine dam‐age. Also, hot coolant or steamcould cause serious personal in‐jury.
•Turn the engine off and wait untilit cools down. Use extreme carewhen removing the radiator cap.Wrap a thick towel around it, andturn it counterclockwise slowly tothe first stop. Step back while thepressure is released from the cool‐ing system.When you are sure all the pressurehas been released, press down onthe cap, using a thick towel, andcontinue turning counterclockwiseto remove it.

(Continued)
•Even if the engine is not operating,do not remove the radiator cap orthe drain plug while the engine andradiator are hot. Hot coolant andsteam may still blow out underpressure, causing serious injury.
WARNING
The electric motor (cool‐ing fan) is controlled byengine coolant tempera‐ture, refrigerant pressureand vehicle speed.
It may sometimes operate evenwhen the engine is not running. Useextreme caution when working nearthe blades of the cooling fan so thatyou are not injured by a rotating fanblades. As the engine coolant tem‐perature decreases, the electric mo‐tor will automatically shut off. Thisis a normal condition.

Check the condition and connections of
all cooling system hoses and heater ho‐ ses. Replace any swollen or deteriora‐
ted hoses.
The coolant level should be filled be‐
tween MAX and MIN (F and L) marks on the side of the coolant reservoir when
the engine is cool.
If the coolant level is low, add enough
distilled (deionized) or soft water. Bring the level to MAX (F), but do not overfill.
If frequent additions are required, have
the system inspected by a professional
workshop. Kia recommends to visit an authorized Kia dealer/service partner.
Recommended engine coolant
• When adding coolant, use only deion‐ ized water or soft water for your ve‐
hicle and never mix hard water in the
coolant filled at the factory. An im‐
proper coolant mixture can result in serious malfunction or engine dam‐
age.
• 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.
• DO NOT USE alcohol or methanol coolant or mix them with the speci‐
fied coolant.
• Do not use a solution that contains more than 60% antifreeze or lessthan 35% antifreeze, which would re‐
duce the effectiveness of the solu‐
tion.
For mixture percentage, refer to the
following table.
