Conventional: Premium quality conventional coolant, which is designed for use in heavy duty diesel engines that contains a chemical inhibitor system, which is Borate/ Nitrite based to protect diesel engines from liner pitting and corrosion. This coolant is low silicate, contains a full charge of heavy duty inhibitors, and is compatible with SCA chemical filters. This coolant is recommended for use in Caterpillar, Detroit Diesel, Cummins and other heavy duty diesel engines. 

Hybrid Organic Acid Technology (HOAT): Coolant that is formulated with Nitrite for heavy duty applications. This coolant provides maximum protection against rust and corrosion. The coolant is phosphate and 2EH (Ethylhexanoic Acid) free. 

Light Duty Extended Life: Coolant that contains a pure organic acid (OAT) inhibitor system that is significant more durable than conventional coolants. This coolant has performance rated at 5 years or 150,000 miles. This coolant is Borate, Nitrite, Phosphates, Silicates and Amines free.  

Mix Fleet Extended Life: Heavy duty mix fleet global extended life organic acid (OAT) coolant specifically designed for complete mixed fleet use. Coolant is recommended for use in all makes and models of foreign and domestic passenger vehicles, light duty and heavy duty diesel applications. Performance rated at 5 years or 150,000 miles for light duty/automotive and 6 years or 600,000 miles for heavy duty diesel. This coolant is Borate, Nitrite, Amine, Phosphate and 2EH (2 Ethylhexanoic Acid) free

Heavy Duty Extended Life OAT: Heavy duty extended life organic acid (OAT) coolant that is Borate, Nitrite, Silicate, Phosphate, Amine and 2EH (2-Ethylhexonic Acid) free. This coolant is dedicated for heavy duty applications that provide up to 600,000 miles on-highway or up to 12,000 hours off-roud. This coolant also includes ingredients to disperse for minor leakage, prevent fouling, control hot surface scaling and has excellent elastomer compatibility (hoses, gaskets and seals). 

M&N Heavy Duty OAT: Heavy duty organic acid (OAT) coolant that contains Nitrite and Molybdate. This coolant provides superior protection  for all engine material of construction and wet sleeve liner cavitation protection. This coolant is CAT EC-1 compatible. The coolant is designed for heavy duty diesel on-road, off-road and farm applications.
