Use High-Quality Ethylene Glycol Coolant

Your vehicle is filled with high-quality ethylene glycol coolant in the cooling system. This is the only type of coolant that should be used, because it helps prevent corrosion in the cooling system, lubricates the water pump, and prevents freezing. Be sure to replace or top up your coolant in accordance with the Maintenance Schedule. Before winter, test the coolant to make sure its freezing point is sufficient for the temperatures expected in winter.
