2020 HYUNDAI VELOSTER engine overheat

6-7
What to do in an emergency
6
4. Check for coolant leaking from the
radiator, hoses or under the vehi-
cle. (If the air conditioning had
been in use, it is normal for cold
water to be draining from it when
you stop.)
5. If engine coolant is leaking out,
stop the engine immediately and
call the nearest authorized
HYUNDAI dealer for assistance.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
reservoir to bring the fluid level in
the reservoir up to the halfway
mark.
7. Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
call an authorized HYUNDAI deal-
er for assistance. While the engine is
running, keep hands,
clothing and tools
away from the mov-
ing parts such as the
cooling fan and drive
belt to prevent seri-
ous injury.
WARNING
Serious loss of coolant indi-
cates a leak in the cooling sys-
tem and should be checked as
soon as possible by an author-
ized HYUNDAI dealer.
CAUTION
Your vehicle is
equipped with a pres-
surized coolant
reserve tank. NEVER
remove the engine
coolant reservoir tank/radiator
cap or the drain plug while the
engine and radiator are HOT.
Hot coolant and steam may
blow out under pressure, caus-
ing serious injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the engine coolant reservoir
tank/radiator cap. Wrap a towel
or thick rag around it, and turn it
counterclockwise slowly to
release some of the pressure
from the system. Step back
while the pressure is released.
When you are sure all the pres-
sure has been released, contin-
ue turning the cap counter-
clockwise to remove it.

The 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.
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-
ties.
Do not drive with no engine
coolant. It may cause water
pump failure and engine seizure,
etc.Checking the Engine Coolant
Level
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 the F and the L marks on
the side of the coolant reservoir
when the engine is cool.
If the coolant level is low, add enough
distilled (deionized) water to bring the
level to the F mark, but do not overfill.
If frequent additions are required, see
an authorized HYUNDAI dealer for a
cooling system inspection.
Recommended engine coolant
When adding coolant, use only dis-
tilled (deionized) water for your
vehicle and never mix hard water in
the coolant filled at the factory.
An improper coolant mixture can
result in severe malfunction or
engine damage.
The engine in your vehicle has alu-
minum engine parts and must be
protected by an ethylene-glycol
with phosphate based coolant to
prevent corrosion and freezing.
Do not use alcohol or methanol
coolant or mix them with the spec-
ified coolant.

Maintenance
Do not use a solution that contains
more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of the
solution.
For mixing percentage, refer to the
following table:
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of
-35°C (-31°F) and higher.

For 1.6 Turbo-GDI
Make sure the coolant cap is
properly closed after refilling
coolant. Otherwise the engine
could be overheated while driv-
ing.
1. Check if the coolant cap label
is straight In front.

2. Make sure that the tiny pro-
trusions inside the coolant
cap is securely interlocked.
