Sinister Diesel 13-18 Dodge Cummins 6.7L Coolant Filtration System

Coolant filters protect the engine cooling system by capturing cast iron particles, rust flakes, and debris that circulate in the coolant over time.

Coolant filters for Duramax, Cummins, and Power Stroke diesel engines are especially popular because diesel cooling systems circulate higher coolant volumes and are more sensitive to silicate and cavitation erosion byproducts in the coolant. Reusable stainless mesh filter inserts reduce ongoing cost compared to paper element types.How does a coolant filter work?An inline coolant filter inserts into the c...
