2006 KIA Optima coolant level

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.

7-15
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.

7-42HEADLIGHT AIMING
ADJUSTMENTBefore performing aiming adjustment,
make sure of the following.
1. Keep all tires inflated to the correct
pressure.
2. Place the vehicle on level ground and
press the front bumper & rear
bumper down several times.
3. See that the vehicle is unloaded
(except for full levels of coolant,
engine oil and fuel, and spare tire, jack,
and tools). Have the driver sit in the
driver’s seat or use equivalent weight.4. Clean the headlight lenses and turn
on the headlight (Low beam).
5. Open the hood.
6. Draw a vertical line (through the
center of each headlight) and the
horizontal line (through the center of
each headlight) on the aiming screen.
1) Horizontal line dimension from
ground: 628 mm (24.72 in)
2) Distance between each vertical
line : 1,306 mm (49.17 in)
And then, draw a parallel line at 30
mm (1.18 in) place under the
horizontal line.
7. Adjust each cut-off line of the low
beam to the parallel line with a
Phillips screwdriver.
ADJUSTMENT AFTER
HEADLIGHT ASSEMBLY
REPLACEMENTIf the vehicle has had front body repair
and the headlight assembly has been
replaced, the headlight aiming should be
checked using the aiming screen as
shown in the illustration. Turn on the
headlight switch. (Low Beam Position)
1. Adjust headlights so that main axis of
light is parallel to center line of the
body and is aligned with point “P”
shown in the illustration.
