2006 KIA Sorento engine coolant

OVERHEATINGIf your temperature gauge indicates
overheating, if you experience a loss of
power, or if you hear a loud knocking or
pinging noise, the engine has probably
overheated. Should any of these
symptoms occur, use the following pro-
cedure:
1. Turn on the hazard warning flash-
er, then drive to the nearest safe
location and stop your vehicle; shift
to Neutral (manual transaxle) or
Park (automatic transaxle) and
apply the parking brake.
2. Make sure the air conditioner is off.
3. If coolant or steam is boiling out of
the radiator, stop the engine and call
an authorized Kia dealer for assis-
tance.
If there is no visible coolant, you
may 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. Use the coolant reservoir
dipstick to check the level. 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 it 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 reser-
voir.If the engine frequently overheats,
have the cooling system checked and
repaired by an Authorized Kia Dealer.

WARNING- Removing Radiator Cap
Never remove the radiator cap
when the engine and radiator
are hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause seri-
ous injury.

b. Driving on dusty roads.
c. Extensive idling or slow-speed driving in stop-and-go traffic.
(4) If necessary, rotate and balance the wheels.
* Note: Check the engine oil and coolant levels every week.

OWNER MAINTENANCEOwner Maintenance Schedule
The owner should perform these
vehicle inspections at the indicated
intervals to ensure safe and depend-
able operation.
Bring any problem to the attention of
an authorized Kia dealer as soon as
possible.When refueling, check the follow-
ing:
 Engine oil level
 Engine coolant level
 Brake (and clutch, if equipped) fluid
level
 Washer fluid levelEvery month, check:
 Tire inflation pressures (cold)
 Coolant level in reservoir (cold
engine)
Every 6 months (for example,
every spring and fall), check:
 Power steering fluid level
 Automatic transmission fluid level
MAINTENANCE

WARNING
Be careful when checking your
engine coolant level. The engine
compartment will be hot and
you could be burned.
WARNING- Engine Cooling Fans
Because your engine cooling
fans are electronically con-
trolled, they will run if the igni-
tion switch is ON, even if the
engine is not running. This
could cause serious injury. To
prevent this, be sure the igni-
tion is OFF, unless you must run
the engine while performing
maintenance or an inspection.

ENGINE COOLING SYSTEMThe high-pressure cooling system
has a reservoir filled with year-round
antifreeze 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 before traveling to a colder cli-
mate.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
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 counter-
clockwise to remove it.

(Continued)
 Even if the engine is not oper-
ating, do not remove the radi-
ator cap or the drain plug
while the engine and radiator
are hot. Hot coolant and
steam may still blow out
under pressure, causing seri-
ous injury.
BL-ENG (CAN)-7.qxd 7/28/05 5:58 PM Page 11

Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen or
deteriorated hoses.
The coolant level should be filled
between MAX and MIN marked on
the coolant reservoir when the
engine is cool.If the coolant level is low, add enough
coolant to bring the level to MAX, but
do not overfill. If frequent additions
are required, see an authorized Kia
dealer for a cooling system inspec-
tion.Changing Coolant
Change coolant according to the
Scheduled Maintenance.
Use only soft (de-mineralized)
water in the coolant mixture.
The engine in your vehicle has alu-
minum engine parts and must be
protected by an ethylene-glycol-
based coolant to prevent corrosion
and freezing.
DO NOT USE alcohol or methanol
antifreeze or mix them with the
specified coolant.
Do not use a solution that contains
more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of the
solution.MAINTENANCE7-12

For mixture percentage, refer to the
following table1. Turn the coolant reservoir cap
counterclockwise to remove it.
2. Loosen the radiator drain plug and
drain the coolant into a suitable
container.
3. With the plug loose, flush the sys-
tem 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 ethyl-
ene-glycol based coolant in accor-
dance with the instructions of the
manufacturer.5. Run the engine at idle with the
coolant reservoir cap off. Slowly
add additional coolant as neces-
sary.
6. At this point, wait until the engine
reaches normal operating temper-
ature. Depress the accelerator two
or three times; then add coolant as
required. Be careful not to burn
yourself.
7. Replace the coolant reservoir cap.
Inspect all connections for leaks
and recheck the coolant level in the
reservoir. Recheck again after a
few days and add coolant as nec-
essary.
