ENGINE COOLANT
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 climate.
Checking the Coolant Level
OIK090007
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 MAX and the MIN 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 MAX mark, but do not overfill. 
If frequent additions are required, see an 
authorized retailer of Genesis Branded 
products for a cooling system inspection.
 WARNING
Never remove the engine 
coolant radiator cap, coolant 
cap or the drain plug while 
the engine and radiator are 
hot. Hot coolant and steam 
may blow out under pressure, 
causing serious injury.
Turn the vehicle off and wait until 
the engine cools down. Use extreme 
care when removing the radiator cap, 
coolant 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.
 Information
The coolant level is influenced by the 
engine temperature. Before checking or 
refilling the coolant, turn the engine off.
 WARNING
The electric motor for the 
cooling fan may continue to 
operate or start up when the 
engine is not running and can 
cause serious injury. Keep 
hands, clothing and tools away 
from the rotating fan blades of 
the cooling fan.
Always turn off the vehicle unless the 
vehicle has to be inspected with the 
engine on. Be cautious as the cooling 
fan may operate if the negative (-) 
battery terminal is not disconnected.
