Zerex from Valvoline is the #1 selling OEM-approved coolant brand. Zerex Dex-Cool Antifreeze/Coolant is proven to maximize engine life in passenger cars and light trucks, and is approved for use in GM, Ford, Chrysler and SAAB vehicles with cooling systems that require an orange antifreeze with Organic Acid Technology (OAT). Specially formulated with a patented carboxylate solution, 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 OAT formula is silicate 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 Dex-Cool Antifreeze/Coolant does not contain amines, borates, nitrates or nitrites. So whether you’re topping off your radiator or doing a complete system flush, trust Zerex Dex-Cool Antifreeze/Coolant. Made for your car. Made by Valvoline.

Since this is concentrated, this one gallon will get me two, when mixed out 50/50 with water. Good buy.

Great antifreeze at a reasonable price. I buy the undiluted because it's cheaper that way. You simply use a large measuring cup to put 2 quarts of distilled waster and 2 quarts of undiluted antifreeze into a separate gallon jug. Shake well and put it in your car.

I bought this antifreeze and it works perfectly it blends with my other antifreeze already having my car no stoppage no clog. Most important thing is not overheated
