![]() Learn About Coolant Formulation and How to Choose the Right Product Some modern vehicles are made with tight engine compartments that don’t feature good air flow, which means they could overheat in a matter of minutes without a functional cooling system.Ĭoolant also serves the purpose of protecting metals and non-metallic elastomers (like rubber and plastic parts) in the engine and the cooling circuit. ![]() Heat can only be effectively transferred with a liquid in the system, so it’s crucial to keep your coolant from freezing or evaporating.Īdditionally, if coolant boils, the vapors formed do not transfer heat well, which means the engine metal can actually melt if the coolant isn’t kept in contact with certain places that need to stay cool. The primary purpose of coolant is transferring heat and preventing engine damage caused by freezing or boiling. Depending on your type of vehicle, you may need a coolant with specialized additives, a coolant formulated for specific manufacturers, or a coolant designed for high-mileage cars. Much like oil, coolant serves the basic function of transferring heat and adding antifreeze protection. Many drivers understand that their vehicle requires coolant, but some drivers aren’t sure which type to use-or what coolant is in the first place. You will need to mix this bottle with distilled water for the desired concentration.Your Cooling System is an Essential Part of Your Vehicle If any coolant is spilled onto the ground, contain the spill and call the state authorities and ask for proper instruction on how to clean up the spill. Instead, contact your state or local municipality for instructions on where to and how to properly dispose of this coolant and protect our environment. Valvoline recommends that spent coolant never be disposed of by dumping into a septic system, storm sewer or onto the ground. ZEREX Original Green is formulated to meet or exceed the following antifreeze specifications: ZEREX Original Green is an approved formula for the following specifications: Valvoline recommends the use of a supplemental coolant additive (SCA) for heavy-duty applications. It contains less than 250 parts per million of silicon as required by the heavy-duty trucking industry. ZEREX antifreeze coolant meets ASTM specification D3306 for automobiles and light trucks and ASTM D4985 for heavy-duty trucks. This coolant is based on IAT (Inorganic Acid Technology). ![]() It contains a high-quality defoamer and will not harm gaskets, hoses, plastics, or original vehicle finishes. ZEREX antifreeze coolant is compatible with many American brands of coolant. The chart below provides mixing information. ZEREX Original Green, when diluted 50% with water, protects modern engine components from winter freezing and summer boilover. The ASTM test data shown on this sheet reflects the high-performance corrosion inhibitors package. Its patented* low silicate formulation protects all engine cooling system metals from corrosion including aluminum. The formulation is designed for both gasoline and diesel engines and has a service life of up to five years or 100,000 miles. Valvoline ZEREX Original Green Antifreeze Coolant is a universal ethylene glycol-based formulation suitable for passenger cars, light trucks, and heavy-duty vehicles.
