If the coolant level drops within a short time of replenishing

removed, causing serious injuries, such as burns.

antifreeze must be used to provide proper lubrication, corrosion protection and cool-
ing. Be sure to read the antifreeze or coolant label.

Be sure to wash it off with water to prevent it from damaging parts or paint.
