Maintenance

Turn the engine off and wait until it cools
down. Use care when removing the radi-
ator cap. Wrap a thick towel around it,
and turn it counterclockwise slowly to the
first stop. Step back while the pressure is
released from the cooling system. When
you are sure all the pressure has been
released, press down on the cap, using a
thick towel, and continue turning counter-
clockwise to remove it.
Changing the coolant
Have the coolant changed by an author-
ized Kia dealer according to the
Maintenance Schedule at the beginning
of this section.
Put a thick cloth or fabric around the radi-
ator cap before refilling the coolant in
order to prevent the coolant from over-
flowing into engine parts such as the
alternator.
CAUTION - Removing radi-
ator cap
Never attempt to remove
the radiator cap while
the engine is operating
or hot. Doing so might
lead to cooling system
and engine damage.
