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.
