What type of antifreeze does the 2011 chevy traverse use?

The 2011 Chevy Traverse uses dexcool antifreeze in the vehicle. It is important that You do not mix different types of antifreeze in Your car together because it can cause damage and corrosion to the cooling system in Your SUV. When You have Your coolant changed at a dealership they will always use dexcool in the vehicle, but if You had it changed at a third party shop they may have used something different. In general if You are unsure of the type of coolant in Your car You should top it of with distilled water. Distilled water will reduce the cooling capacity slightly, but it will not harm anything in Your vehicle and then You can find out what type of coolant You have.
