G12++ Coolant - 1 Gallon (3.78 Liters)

Valvoline ZEREX G-40 antifreeze coolant is premium automotive engine coolant developed by BASF AG and Valvoline. The patent-pending hybrid carboxylate formulation has an extended service life. It incorporates stateof-the-art organic acid technology in an ethylene glycol base for protection of all cooling system metals including aluminum.

ZEREX G-40 meets both the ASTM D3306, D4985, and D6210 specifications. When diluted 50% with water, it protects modern engine components from winter freezing and summer boiling. Valvoline recommends ZEREX G-40 for late model VAG (G12++) vehicles. It is dyed pink to distinguish its unique chemistry from traditional green and yellow coolants.
