Severe winter climate
[SV20490(ALL)09/95]
If you drive in extremely cold climates (less than -34˚F [-36˚C]),
it may be necessary to increase the coolant concentration above
50%. 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
concentration above 60%. Leave a 50/50 mixture of engine
coolant and water in your vehicle year-round in non-extreme
climates.
