Description:

Valvoline’s ZEREX™ Original Green antifreeze coolant is a universal ethylene glycol-based formulation suitable for passenger cars, light trucks and heavy duty vehicles. The formulation is designed for both gasoline and diesel engines and has a service life of up to five years or 100,000 miles. Its patented* low silicate formulation protects all engine cooling system metals from corrosion including aluminum. The ASTM test data shown on this sheet reflects the high performance corrosion inhibitors package.

ZEREX™ Original Green, when diluted 50% with water, protects modern engine components from winter freezing and summer boil over. The chart at the top right provides mixing information. ZEREX antifreeze coolant is compatible with major American brands of coolant. It contains a high quality defoamer and will not harm gaskets, hoses, plastics or original vehicle finishes.

ZEREX antifreeze coolant meets ASTM specification D3306 for automobiles and light trucks and ASTM D4985 for heavy duty trucks. It contains less than 250 parts per million of silicon as required by the heavy duty trucking industry. Valvoline recommends the use of a supplemental coolant additive (SCA) for heavy duty applications.
