Maxima Coolanol is a high performance coolant and antifreeze formulated to provide protection from overheating and freezing under even the most extreme conditions. The extensively developed formulation combines premium ethylene glycol and pure deionized water with advanced additive chemistries to provide optimum cooling, water pump lubrication and corrosion protection for all liquid-cooled engines. The robust anti-foam system minimizes pump cavitation, thereby increasing cooling capacity and extending equipment life. High performance coolant Premixed with pure, deionized water for optimum performance and convenience Enables maximum horsepower by controlling engine temperatures Advanced formulation protects against rust, corrosion and cavitation Nitrate, amine and borax free! 100% biodegradable in unused form Safely mixes with most OEM glycol-based anti-freeze/coolants 1/2 gallon MPN: 82964 Usage For all liquid-cooled engines recommending conventional or hybrid ethylene glycol-based anti-freeze/coolants. Ready-to-use formulation requires no mixing. Video California Residents: Proposition 65 warning
