Based on the material data sheet I found, the major ingredient is ethylene glycol (~70%) with the balance propylene glycol and some corrosion inhibitors. Those are the same ingredients found in Prestone and Peak antifreeze respectively. Because the heat capacity of ethylene glycol is significantly less than water or a water-glycol mix, you can expect the engine to run hotter. Whether that's a problem depends on the condition of the cooling system.
Water is used because its one of the best heat transfer agents available. Glycol is added to the water to keep the it from freezing, not to make it a better heat transfer agent.
