ALLTEMP® HEAVY DUTY EXTENDED LIFE COOLANT uses advanced organic acid technology (OAT) additive/inhibitor package formulated with a proprietary stabilization system to improve the durability of its carboxylate salt base and extend its range of compatibility with both conventional inorganic salt and OAT-type antifreezes. It provides superior engine protection against freezing, boil over, cavitation erosion, corrosion and scale and a service life of 600,000 miles or 12,000 hours, with inhibitor addition required at 270,000-330,000 miles or 6000 hours. It contains no phosphates or amines, and employs mono- and dibasic organic acid salts with tolytriazole, nitrites and molybdates to protect all six standard metal alloys (copper, solder, brass, cast iron, steel, and aluminum). It meets Caterpillar EC-1. ALLTEMP®™ Heavy Duty Extended Life Antifreeze eliminates the need for SCA’s at initial fill and top off because it has a minimum nitrite level of 2400 PPM which reduces long term maintenance cost and problems related to SCA variability. Slowly depleted phosphonocarboxylates and other proprietary ingredients provide broad range metal protection and guard the cooling system against corrosion and cavitation erosion for many years. In addition, it contains additives to minimize hot surface scaling while also preventing heat transfer surface fouling due to minor oil leakage.
ALLTEMP®™ Heavy Duty Extended Life Coolant is recommended for use in heavy duty engines. It is also recommended for use in the cooling systems of all types of industrial internal combustion engines, including systems containing large amounts of aluminum.
