NAPA Fully Formulated SCA Precharged Heavy Duty Vehicles Fuchsia IAT Antifreeze + Coolant Concentrate 1 gal (US)

Heavy-Duty Antifreeze Coolant Concentrate for Fleets

Get the 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 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 helps maintain integrity when topping off each time.

NAPA concentrated coolant requires mixing with water before use, allowing you to customize the freeze and boil protection levels to perfectly match your specific climate and vehicle needs. Choosing antifreeze and coolant concentrate also offers potential cost savings in the long run, essentially giving you twice the volume compared to prediluted options. It's crucial, however, to follow the manufacturer's instructions as using incorrect dilutions can potentially damage your engine.

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.
