The Cat 435-5142 Advanced High Efficiency Coolant Filter helps extend engine life and reduce machine-shop operating costs. Coolant filters have typically been used to dose systems using Cat DEAC (Diesel Engine Antifreeze Coolant) and Cat NGEC (Natural Gas Engine Coolant) with Cat SCA (Supplemental Coolant Additive). Using Genuine Cat Coolant Filters keeps the coolant properly treated with inhibitors which protects your cooling system from corrosion, mineral deposit formation, and cavitation of the cylinder liners.
