Maintenance and Specifications 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. 286
