Severe climates
If you drive in extremely cold
climates (less than Ć36 ° C [Ć34 ° F]):
• It may be necessary to
increase the coolant
concentration above 50%.
• NEVER increase the coolant
concentration above 60%.
• Increased engine coolant
concentrations above 60% will
decrease the overheat
protection characteristics of
the engine coolant and may
cause engine damage.
• Refer to the chart on the
coolant container to ensure the
coolant concentration in your
vehicle will provide adequate
freeze protection at the
temperatures in which you
drive in the winter months.
If you drive in extremely hot
climates:
• It is still necessary to
maintain the coolant
concentration above 40%.
• NEVER decrease the coolant
concentration below 40%.
Decreased engine coolant
concentrations below 40% will
decrease the corrosion and the
freeze protection
characteristics of the engine
coolant and may cause engine
damage.
