Specially formulated with state-of-the-art Si-Organic Acid Technology (Si-OAT) in an ethylene glycol base, Zerex is made for your car and protects better than industry standards against corrosion, leaking, deposits as well as freezing and boiling – the four main causes of cooling system failure, which is the leading cause of engine breakdown. Our premium grade long-life Si-OAT formula is nitrite, amine and phosphate-free. It protects from corrosion, scale and rust, so radiators, water pumps and other metal cooling system parts (including aluminum) stay clean and your antifreeze flows and functions properly. Zerex G40 Antifreeze/Coolant contains no imidazole, borates or nitrates. So whether you’re topping off your radiator or doing a complete system flush, trust Zerex G40 Antifreeze/Coolant.
