ENGINE COOLANT/LIQUID-COOLED INTERCOOLER 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.

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.
