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. Review: Solid product for you vehicle coolant needs - Online purchase is more cost effective than getting it at the parts store. Additionally, not all locations have this available without ordering it. I bought this for its value and convenience of desertcart delivery. Were I live (Nashville area), it is a very fast delivery. It is good to have some coolant around if doing minor adjustments or maintenance where you loose some coolant and need to top up. Or if you are doing major work requiring a full refill, get the required amount ahead of your work. Ironically, it is the coolant supplied at the dealer (but costs more needless to say). I personally like the concentrate to mix up what I need and ratio mix. I've used this product for a number of years with no difference in vehicle cooling performance from OEM.
