Severe climates
If you drive in extremely cold climates (less than –34°F [–36°C]):
• It may be necessary to increase the coolant concentration
above 50%.
• NEVER increase the coolant concentration above 60%.
• Engine coolant concentrations above 60% decreases the
overheat protection characteristics of the engine coolant and
may cause engine damage.
• If available, refer to the chart on the coolant container to
ensure the coolant concentration in your vehicle provides
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%.
• Engine coolant concentrations below 40% decreases the
corrosion protection characteristics of the engine coolant and
may cause engine damage.
• Engine coolant concentrations below 40% decreases the freeze
protection characteristics of the engine coolant and may cause
engine damage.
• If available, refer to the chart on the coolant container to
ensure the coolant concentration in your vehicle provides
adequate protection at the temperatures in which you drive.
