The information provided in this “Coolant Recommendation” section should be used with the “Lubricants Information” provided in the latest revision of Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations". This manual may be found on the Web at Safety.Cat.com.Due to the use of aluminum radiators, some coolant samples may show lower levels of nitrates or other ELC components as a result of the aluminum. Additional coolant additives may be required to aid with use in aluminum radiators. Consult your Cat dealer.The following two types of coolants may be used in Cat diesel engines:Preferred - Cat ELC (Extended Life Coolant)Acceptable - Cat DEAC (Diesel Engine Antifreeze/Coolant)
Never use water alone as a coolant. Water alone is corrosive at engine operating temperatures. In addition, water alone does not provide adequate protection against boiling or freezing.
