Kia Optima 2017 - If the Engine Overheats

IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you will experience a loss
of power, or hear loud pinging or knock‐
ing, the engine is probably too hot. If
this happens, 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 (Automat‐
ic transaxle / Dual clutch transmis‐
sion) or neutral (manual transaxle)
and set the parking brake. If the air
conditioning is on, turn it off.
3. If engine coolant is running out un‐
der the vehicle or steam is coming
out from the hood, stop the engine.
Do not open the hood until the
coolant has stopped running or the
steaming has stopped. 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. If the fan is
not running, turn the engine off.
4. Check to see if the water pump
drive belt is missing. If it is not
missing, check to see that it is
tight.
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 be draining from it
when you stop).
WARNING
While the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
5. If the water pump drive belt is bro‐
ken or engine coolant is leaking out,
stop the engine immediately and
we recommend that you call an au‐
thorized Kia dealer.
WARNING
Do not remove the radiator cap
when the engine is hot. This can al‐
low coolant to blow out of the open‐
ing and cause serious burns.
6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor‐
mal. Then, if coolant has been lost,
carefully add coolant to the reser‐
voir to bring the fluid level in the
reservoir up to the halfway mark.
7. Proceed with caution, keeping alert
for further signs of overheating. If
overheating happens again, we rec‐
ommend that you call an author‐
ized Kia dealer.
CAUTION
• Serious loss of coolant indicates
there is a leak in the cooling sys‐
tem and we recommend that
the system be checked by an
authorized Kia dealer.
• 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 quantities.
