Engineered specifically for 2011 through 2016 Ford F-250, F-350, F-450, and F-550 Super Duty trucks equipped with the 6.7L Powerstroke turbo diesel engine, the Dieselsite Coolant Filtration System (CFIK67) removes suspended contaminants from the engine's primary cooling loop. As the pioneers of modern diesel bypass coolant filtration, Dieselsite designed this system to target the manufacturing casting sand, mineral deposits, and metallic debris that continuously circulate through the engine block.

Without active bypass filtration, these abrasive solids score water pump impeller seals, causing premature leaks, and foul the narrow liquid channels of the primary engine oil cooler and EGR cooler. The Dieselsite kit bleeds off a small fraction of pressurized coolant, routes it through an efficient spin-on filter, and returns clean fluid back into circulation without altering operating temperatures. It also includes dual brass shut-off ball valves directly in the assembly, making filter swaps clean and effortless without spilling coolant.

Key Features & Benefits

• Original Bypass Filtration Pioneer: Effectively traps casting sand, scale, and metal shavings to extend water pump, radiator, and oil cooler life.
