For more than 20 years, Engine Ice has been the leader in coolant for your Powersports and motorsports vehicles. Engine Ice's proprietary propylene glycol-based blend is both an antifreeze and coolant. It provides boil-over protection to 256F and freezing protection to -26F. Engine Ice chooses propylene glycol as the base because of its performance and environmental benefits. It is considerably less toxic than the ethylene glycol base found in many other antifreeze/coolants on the market. Motorcycles, ATV's, SXS's, Snowmobiles, and all 2-Cycle engines benefit by using Engine Ice Powersport Coolant in the convenient 1.75 Liter pouch.
