Cummins 3666286 Engine Coolant

Research indicates that more than 40 percent of total engine repair costs are related to problems in the cooling system.

Repairs are costly, and downtime due to cooling system problems can affect your equipment's operation as well as upset customers. Cooling system products provide unmatched protection with an easy maintenance program so that you can keep engines running longer and stronger—avoiding unnecessary repairs altogether!

Products are designed to keep your engine safe from damaging cooling system problems, including scale and corrosion—as well as pitting of the water pump's liner.

Coolants are manufactured to the highest standards and meet all major OEM performance specifications. You can be sure that cooling system products will provide unmatched protection for your engine.

Coolants and coolant additives are compatible with all other kinds of coolants and can be used in engines powered by diesel, gasoline or natural gas.

Proper engine coolant selection is critical to prolonging the life of many elastomeric materials, preventing corrosion and cavitation in cylinder liners (which could lead to premature failure).

Find a coolant that meets the correct Cummins engineering standard (CES) for your engine.

Customers may use either a premixed, heavy-duty coolant or a mixture of high-quality water and concentrated coolant.
