2006 KIA Optima coolant reservoir

ENGINE TEMPERATURE
GAUGEThis gauge shows the temperature of the
engine coolant when the ignition switch
is ON.
If the gauge pointer moves beyond the
normal range area toward the H position,
it indicates overheating that may damage
the engine.
Do not continue driving with an
overheated engine. If your vehicle
overheats, refer to “Overheating” in the
Index.
WARNINGS AND
INDICATORSWARNING LIGHTS/
AUDIBLE INDICATORSCHECKING OPERATIONAll the warning lights, except the brake
warning light, are checked by turning the
ignition switch ON (you do not need to
start the engine). Any light that does not
come ON should be checked by an
Authorized Kia Dealer.
If the brake system warning light does
not come ON when the ignition switch is
in the START position, have the system
checked by an Authorized Kia Dealer.
After starting the engine, check to make
sure that all warning lights are OFF. If
any are still ON, this indicates a situation
that needs attention. When releasing the
parking brake, the brake system warning
light should go OFF.
PARKING BRAKE AND
BRAKE FLUID WARNINGPARKING BRAKE WARNINGThis light comes on when the parking
brake is applied with the ignition switch
in the START or ON position. The
warning light should go OFF when the
parking brake is released.LOW BRAKE FLUID LEVEL
WARNINGIf the warning light remains ON when
the parking brake is released, it may
indicate that the brake fluid level in the
reservoir is low.
If the warning light remains ON:
1. Drive to the nearest safe location and
carefully stop your vehicle.
2. With the engine stopped, check the
brake fluid level immediately and
add fluid as required.
All brake components should also be
checked immediately for fluid leaks.

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.
EMERGENCY STARTINGJUMP STARTINGJump starting can be dangerous if done
incorrectly. Therefore, to avoid harm to
yourself or damage to your vehicle or
battery, follow the jump starting
procedures on the next page. If in doubt,
we strongly recommend that you have a
competent technician or towing service
jump start your vehicle.

WARNING - Removing
Radiator Cap
Do not remove the radiator cap
when the engine and radiator
are hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause
serious injury.
✻
NOTICE
Use only a 12volt jumper system.
You can damage a 12volt starting
motor, ignition system, and other
electrical parts by using a 24-volt
power supply (two 12-volt batteries
in series or a 24-volt motor
generator set).

MAINTENANCE
7-14ENGINE COOLING
SYSTEMThe cooling system is a high-pressure
type with a reservoir and is filled with
year-round antifreeze coolant at the
factory.
Check the antifreeze protection and
coolant level at least once a year, at the
beginning of the winter season, and
before traveling to a colder climate.
CHECKING THE
COOLANT LEVEL
WARNING - Removing
Radiator Cap
 Never attempt to remove the
radiator cap while the engine
is operating. Doing so might
lead to cooling system
and/or engine damage and
could result in serious
personal injury from
escaping hot coolant or
steam.
 Turn the engine off and wait
until it has cooled. Even then,
use extreme care when
removing the radiator 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
counterclockwise to remove
it.
 Even if the engine is not
operating, do not remove the
radiator cap or the drain plug
while the engine and radiator
are hot. Hot coolant and
steam may still blow out
under pressure, causing
serious injury.

Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or
deteriorated hoses.
The coolant level should be full in the
radiator and between F (Full) and L
(Low) on the coolant reservoir tank
when the engine is cool.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 COOLANTChange 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% coolant or less than
35% coolaut, which would reduce
the effectiveness of the solution.
For mixture percen-tages, refer to the
following table.
1. Turn the radiator cap counterclockwise
and remove it.
2. Loosen the radiator drain plug and
drain the coolant into a suitable
container.

7-163. With the drain plug loose, flush the
system with running water.
4. Drain the system completely and
retighten the drain plug. Add the
necessary amount of ethylene glycol
based coolant and water to provide
the required protection against
freezing and corrosion.
In extremely cold climates, add the
necessary amount of ethylene glycol-
based coolant in accordance with the
instructions of the coolant
manufacturer.5. Run the engine at idle with the
radiator cap off. Slowly add
additional coolant if necessary.
6. At this point, wait until the engine
reaches normal operating temperature.
Depress the accelerator two or three
times; then add coolant if required. Be
careful not to burn yourself.
7. Install the radiator cap. Inspect all
connections for leaks and recheck the
coolant level in the reservoir.
Recheck again after a few days of
driving and add coolant as necessary.

BODY LUBRICATIONAll moving points of the body, such as
doors, hood hinges and locks, should be
lubricated each time the engine oil is
changed.
Use a non-freezing lubricant on locks
during cold weather.
Make sure the engine hood secondary
latch keeps the hood from opening when
the primary latch is released.
AIR CLEANERELEMENT REPLACEMENTA paper air cleaner filter is used. It must
be replaced when necessary, and should
not be cleaned and reused.
1. Remove the four (4) air cleaner cover
attaching clips.
2. Wipe the inside of the air cleaner
housing with a clean, damp cloth.
3. Replace the air cleaner element.

WARNING
Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
Radiator coolant can severely
obscure visibility when
sprayed on the windshield
and may cause loss of
vehicle control or damage to
paint and body trim.
Windshield washer fluid
agents contain some
amounts of alcohol and can
be flammable under certain
circumstances. Do not allow
sparks or flame to contact
the washer fluid or the
washer fluid reservoir.
Damage to the vehicle or it's
occupants could occur.
Windshield washer fluid is
poisonous to humans and
animals. Do not drink and
avoid contacting windshield
washer fluid. Serious injury
or death could occur.
