Prime® Antifreeze/Coolant Conventional Green Low Silicate Formulation is an ethylene glycol based product which meets or exceeds ASTM requirements for use in cars, light duty and heavy duty trucks. It contains inhibitors to prevent rust and corrosion for all cooling system metals including aluminum. A 50/50 mixture of Prime® Antifreeze/Coolant Conventional Green Low Silicate Formulation and water provides freeze protection to -34F and raises the cooling system boiling point to 265F when a 15 lb. pressure cap in good condition is used. When used as directed, Prime® Antifreeze/Coolant Conventional Green Low Silicate Formulation provides full protection for a minimum of one year. For Heavy Duty applications the use of Supplemental Coolant Additives (SCAs) is recommended.
CAUTION: To avoid serious burns do not remove radiator cap from a hot cooling system. Check owner's manual for any special cooling system service instructions
IMPORTANT SAFETY INFORMATION: Antifreeze/coolant is poisonous. Clean up any leaks or spills immediately. Tighten the child resistant cap and store antifreeze away from children and animals. Do not store antifreeze in open or unlabled containers.
Wash exposed skin thoroughly with soap and water after use.
Inspect system carefully to ensure that all components (hoses, clamps, etc.) are in satisfactory condition and that there are no leaks.
Completely drain the entire cooling system. Always properly dispose of used product. Flush cooling system thoroughly with clean tap water. If cooling system is dirty, flush system with a quality radiator cleaner to remove rust, scale and sediment.
Based on cooling system capacity, generally given in the owner's manual, determine from the chart on this container the quantity of Prime® Antifreeze/Coolant Conventional "Green" Low Silicate Formulation required to provide desired freeze protection. At least a 50/50 mixture of this product and water is recommended. NOTE: Maximum recommended mixture strength is two parts of this product and one part water.
Pour the desired quantity of Prime® Antifreeze/Coolant Conventional "Green" Low Silicate Formulation into the cooling system; add clean water to bring mixture to the level recommended by the manufacturer. To assure proper mixing and to release entrapped air, run engine with heater temperature control on high until normal engine operating temperature is reached. Turn off engine and allow to cool. Recheck coolant level and add water if necessary. For Heavy Duty applications the use of Supplemental Coolant Additives (SCAs) is recommended.
