Get superior engine protection for longer periods of time with the specially-formulated NAPA Extended Life Antifreeze & Coolant. Featuring a technology that is compatible for use in all automobiles, light-duty trucks and motorcycles (regardless of make, model, year or original antifreeze color), this all-vehicle antifreeze utilizes long-lasting inhibitors to prevent rust, corrosion and scale buildup within the cooling system. Its specialized formula effectively regulates engine temperature.

NAPA 50/50 prediluted antifreeze and coolant is premixed with a 50% concentration of ethylene glycol base and 50% deionized water, which eliminates the need for any guesswork or measuring when adding it to your vehicle. By raising the boiling point and lowering the freezing point of the water within the cooling system, this precise predilution ensures optimal freeze and overheat protection, safeguarding your engine in both extreme cold and scorching heat.

Providing worry-free protection and reliable performance across all makes and models, this universal antifreeze coolant is a convenient, ready-to-use solution. When a complete cooling system flush and fill is performed, the extended-life technology can keep your engine secure for up to five years or 150,000 miles. By choosing NAPA Extended Life Antifreeze & Coolant, you benefit from fewer coolant changes, reduced maintenance costs and guaranteed long-term engine preservation.
