HYBRID ORGANIC ACID TECHNOLOGY FIGHTS RUST, SCALE & CORROSION 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 YELLOW 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).


Zerex from Valvoline is the #1 selling OEM-approved coolant brand. Zerex G05 Antifreeze/Coolant is proven to maximize engine life in newer Ford, Chrysler and Mercedes-Benz cars, light trucks and heavy-duty vehicles. Suitable for both gasoline and diesel engines, its original long-life chemistry is specially formulated with the highest quality virgin ethylene glycol and Hybrid Organic Acid Technology (HOAT). 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 low-silicate, reduced pH, phosphate-free formula with Hybrid Organic Acid Technology (HOAT) protects all cooling system metals (including aluminum) from corrosion. It contains nitrites that protects diesel-engine cylinder liners from cavitation, while deposit control additives guard against hardwater deposits and scale. So radiators, water pumps and other metal cooling system parts stay clean and your antifreeze flows and functions properly. Whether you’re topping off your radiator or doing a complete system flush, trust Zerex G05 Antifreeze/Coolant. Made for your car. Made by Valvoline.

Open FAQ How Does Engine Coolant Work?

How Does Engine Coolant Work?

Engine coolant is mixed with water, usually at a 50/50 ratio, and poured into the proper reservoir in your engine. The chemical ethylene glycol is used as a base to create a liquid that is pumped through your car’s engine to regulate and maintain an optimal operating temperature during extreme hot or cold weather conditions.

Open FAQ What Makes Each Antifreeze Type Different?

What Makes Each Antifreeze Type Different?

All coolant is made up of the base chemical ethylene glycol. Whether it's green, pink or orange, they are all the same at their base. For instance, what makes Multi-Vehicle Antifreeze/Coolant different from ZEREX™ Original Green is additives and dyes that are designed for use in higher-mileage vehicle types, whereas Original Green is a more general formula used worldwide for decades.

Open FAQ How Often Does My Car Need New Coolant?

How Often Does My Car Need New Coolant?

Most fluids your vehicle needs should be drained and replaced at various intervals in order to be effective. The same goes for your coolant. At least twice a year you should check your coolant levels—before the summer heat and before the winter cold. Consult your vehicle’s owner's manual for more precise information on when to flush and replace the coolant in your vehicle.
