## 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.

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.
