Description

The Sinister Diesel Coolant Filtration System helps to clean engine coolant to extend engine life. Contaminants such as casting sand, metal shavings, rust, and mineral deposits can diminish the cooling system's ability to absorb heat and cause premature wear to the water pump bearings, EGR cooler, and oil cooler.

The filter block is constructed from anodized aluminum and uses a supplied bracket that mounts to factory holes without drilling. It includes a WIX or CAT coolant filter, which can be easily unscrewed for replacement.
