2. Make sure the air conditioner is off.
3. If coolant or steam is boiling out of the radiator,
stop the engine, then turn the ignition switch to the
ON position. Do not restart the engine. The radiator
cooling fan will automatically operate with the
ignition switch in the ON position. If the cooling
fan does not operate, call an Authorized Kia Dealer
for assistance.
If coolant is not boiling out, allow the engine to
idle and open the hood to permit the engine to cool
gradually.
If the temperature does not go down with the
engine idling, stop the engine and allow sufficient
time for it to cool.
4. The coolant level should then be checked. If the
level in the reservoir is low, look for leaks at the
radiator hoses and connections, heater hoses and
connections, radiator, and water pump. If you find a
major leak or another problem that may have
caused the engine to overheat, do not operate the
engine until the problem has been corrected. Call
an Authorized Kia Dealer for assistance.
If you do not find a leak or other problem, carefully
add coolant to the reservoir.
If the engine frequently overheats, have the cooling
system checked and repaired.

WARNING - Removing
Radiator Cap

engine and radiator are hot. Scalding hot
coolant and steam may blow out under
pressure. This could cause serious injury.
