Maintenance -> ENGINE COOLANT for Your Hyundai I10 4 Door Second Generation (2013-2019)

Maintenance  
ENGINE COOLANT  
The high-pressure cooling system has a  
reservoir filled with year round antifreeze  
coolant. The reservoir is filled at the fac-  
tory.  
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.  
Changing the engine oil and filter  
Checking the coolant level  
We recommend that the engine oil and  
filter be replaced by an authorized  
HYUNDAI dealer.  
WARNING  
Removing radiator  
cap  
WARNING  
Used engine oil may cause skin irri-  
tation or cancer if left in contact  
with the skin for prolonged periods  
of time. Used engine oil contains  
chemicals that have caused cancer  
in laboratory animals. Always pro-  
tect your skin by washing your  
hands thoroughly with soap and  
warm water as soon as possible  
after handling used oil.  
• Never attempt to remove the radi-  
ator cap while the engine is oper-  
ating or hot. Doing so might lead  
to cooling system and engine  
damage and could result in seri-  
ous personal injury from escap-  
ing hot coolant or steam.  
• Turn the engine off and wait until  
it cools down. 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.

Maintenance  
Recommended engine coolant  
• Use only soft (distilled) water in the  
coolant mixture.  
• The engine in your vehicle has alu-  
minum engine parts and must be pro-  
tected by an ethylene-glycol-based  
coolant to prevent corrosion and freez-  
ing.  
(Continued)  
• Even if the engine is not operat-  
ing, 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 seri-  
ous injury.  
• DO NOT USE alcohol or methanol  
coolant 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.

The electric motor (cool-  
ing fan) is controlled by  
Check the condition and connections of  
all cooling system hoses and heater  
hoses. Replace any swollen or deterio-  
rated hoses.  
The coolant level should be filled  
between F (MAX) and L (MIN) marks on  
the side of the coolant reservoir when the  
engine is cool.  
If the coolant level is low, add enough  
specified coolant to provide protection  
against freezing and corrosion. Bring the  
level to F (MAX), but do not overfill.  
If frequent additions are required, we rec-  
ommend that the system be inspected by  
an authorized HYUNDAI dealer.

It may sometimes operate even  
when the engine is not running.  
Use extreme caution when working  
near the blades of the cooling fan  
so that you are not injured by a  
rotating fan blades. As the engine  
coolant temperature decreases, the  
electric motor will automatically  
shut off.This is a normal condition.

Maintenance  
Changing the coolant  
We recommend that the coolant be  
replaced by an authorized HYUNDAI  
dealer.  
CAUTION  
Put a thick cloth around the radiator  
cap before refilling the coolant in  
order to prevent the coolant from  
overflowing into the engine parts  
such as the generator.

WARNING - Coolant  
• Do not use radiator coolant or  
antifreeze in the washer fluid  
reservoir.  
WARNING  
Radiator cap  
• Radiator coolant can severely  
obscure visibility when sprayed  
on the windshield and may cause  
loss of vehicle control or damage  
to paint and body trim.  
Do not remove the radiator cap  
when the engine and radiator are  
hot. Scalding hot coolant and  
steam may blow out under pres-  
sure causing serious injury.
