FULL FORCE® Antifreeze + Coolant

Q: Why is it important to mix antifreeze with water?

A: Antifreeze contains chemicals that protect your engine against rust and corrosion, as well as freeze-up and boil over protection. Water is required to activate the chemicals in the inhibitor package. Furthermore, adding water to antifreeze actually increases the freeze-up and boil over protection provided. For example, a mix of 50% antifreeze and 50% water provides freeze-up protection down to -34°F and boil over protection up to 265°F. In comparison, a mix of 70% antifreeze and 30% water provides freeze-up protection down to -84°F and boil over protection up to 276°F. However, we do not recommend adding more than 70% antifreeze. This would limit the corrosion and freeze up protection and heat transfer capabilities of the antifreeze.

Q: Can I mix ordinary tap water with antifreeze?

A: Yes, tap water is commonly used for mixing with antifreeze, however, deionized water or distilled water is preferred. Do not use water softened with salts to mix with antifreeze.

Q: What is the shelf life of antifreeze?

A: If the product is still in the original sealed container, then it has a shelf life of many years. We recommend that antifreeze be used within one year of purchase.

Q: How should I dispose of used antifreeze?

A: All laws and regulations should be observed when disposing of Antifreeze/Coolant and Radiator Fluids. Call the EPA or the office of your state or local environment agency for details on disposal procedures.
