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.

  • Unsurpassed freeze protection and anti-boil performance outperforms industry standards
  • Si-organic acid technology resists corrosion and rust while protecting all cooling system metals (including aluminum)
  • High-quality additives protect against leaks and won’t harm gaskets, hoses, plastics or original vehicle finish
  • Pre-mixed violet formula is ready-to-use in a 50/50 ratio with deionized water to protect all modern engine components from winter freezing (-34F) and summer boiling (265F).
  • 5 year/150,000 mile guarantee protects against engine failure caused by freeze-ups or boil-overs
  • Batch-tested in the lab, fleet-tested in the real world to help car and truck owners achieve optimal performance and maximize engine life.
  • Contains 30 – 50 ppm of denatonium benzoate as a bittering agent
