Refer to the chart on the coolant
container to ensure the coolant
concentration in your vehicle is such
that the coolant will not freeze at
the temperature level in which you
drive during winter months. Never
increase the engine coolant

50/50 mixture of engine coolant and
water in your vehicle year-round in
non-extreme climates.
