Zerex from Valvoline is the #1 selling OEM-approved coolant brand. Zerex G48 Antifreeze/Coolant is proven to maximize engine life in cars and light trucks. Its premium formulation is suitable for BMW, Chrysler 2001 and older, Ford 2002 and older, GM 1996 and older, Mercedes-Benz, Mini and Volvo engines. Specially formulated with NAP-free Hybrid Organic Acid Technology (HOAT) 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 lower-silicate, reduced pH, phosphate-free formula with Hybrid Organic Acid Technology (HOAT) protects all cooling system metals (including aluminum) from corrosion. It contains nitrates that protects diesel-engine cylinder liners from cavitation, while deposit control additives guard against hardwater deposits and scale. So radiators, water pumps and other metal cooling system parts stay clean and your antifreeze flows and functions properly. Whether you’re topping off your radiator or doing a complete system flush, trust Zerex G48 Antifreeze/Coolant.
