If the engine overheats
If your temperature gauge indicates
overheating, you experience a loss of
power, or hear a loud pinging or knock
-
ing, the engine is probably too hot.
You should:
1. Pull off the road and stop as soon as it
is safe to do so.
2. Place the shift lever in P and set the
parking brake.
3. If the air conditioning is on, turn it off.
4. If engine coolant is leaking under the
vehicle or steam is coming out from
underneath the hood, stop the engine.
Do not open the hood until the cool
-
ant has stopped leaking or the steam
has stopped.
5. If there is no visible loss of engine
coolant and no steam, leave the
engine running and check to be sure
the engine cooling fan is operating.
1) If the fan is not operating, turn the
engine off.
6. Check to see if the water pump drive
belt is missing.
1) If it is present, check to see that it is
tight.
2) If the drive belt seems to be satis
-
factory, check for coolant leaking
from the radiator, hoses or under
the vehicle. (If the air conditioning
had been in use, it is normal for
cold water to drain from it when
you stop).
WARNING
Under the hood
While the engine is running, keep
hair, hands and clothing away
from moving parts, such as the
fan and drive belts, to prevent injury.
7. If the water pump drive belt is broken
or engine coolant is leaking out, stop
the engine immediately and call the
nearest authorized Kia dealer for
assistance.
8. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to normal.
If coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
9. Proceed with caution, keeping alert
for further signs of overheating. If
overheating happens again, call an
authorized Kia dealer for assistance.
WARNING
Engine coolant reservoir cap
Do not remove the engine cool -
ant reservoir cap when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious burns.
CAUTION
僅 Serious loss of coolant indicates there
is a leak in the cooling system and this
should be checked as soon as possi -
ble by an authorized Kia dealer.
僅 When the engine overheats from low
engine coolant, suddenly adding
engine coolant may cause cracks in
the engine. To prevent damage, add
engine coolant slowly in small quanti
