Heavy-Duty Antifreeze Coolant 50/50 Prediluted for Fleets

Get ultimate protection for all heavy-duty engines with NAPA SCA Precharged Heavy-Duty Antifreeze & Coolant. Containing an advanced technology known as Supplemental Coolant Additives, NAPA heavy-duty, ready-to-use engine oil provides extra anti-corrosion and cavitation protection for demanding fleet operations, along with safeguarding against freezing and overheating. This heavy-duty antifreeze coolant requires no additional SCAs during the initial fill, plus it helps maintain integrity when topping off each time.

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.

This diesel engine antifreeze coolant is also compatible with all heavy-duty gasoline and natural gas cooling systems. It features a phosphate-free, low-silicate formulation with nitrite for exceptional wet sleeve liner cavitation protection. The additives form a layer on metal surfaces, preventing rust and scale buildup that lead to reduced cooling and costly repairs. NAPA SCA Precharged Heavy-Duty Antifreeze & Coolant ensures optimal engine performance, reduces downtime and extends the life of your vehicles.
