ARCTIQ RED 50/50 55 GAL ANTIFREEZE

It's a ready-to-use antifreeze formulated for diesel engines in heavy trucks and off-road equipment, combining organic acid inhibitors with nitrite and molybdate to protect all engine metals like steel, aluminum, cast iron, copper, and brass. You use this to prevent freezing and boil-over while protecting against cylinder liner cavitation and pitting, without needing to add supplemental coolant additives (SCAs). It's typically chosen for extended service intervals—up to 600,000 on-road miles—reducing maintenance downtime and water pump issues caused by silicate or phosphate dropout.
