Description

Zerex from Valvoline is the #1 selling OEM-approved coolant brand. Zerex G40 Antifreeze/Coolant is proven to maximize engine life in cars and light trucks. It’s the premium carboxylate formulation recommended for BMW, Mercedes-Benz, Porsche and VW cars and light trucks, as well as older Audi and Volvo vehicles. 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. Made for your car. Made by Valvoline.
