Sinister Diesel 03-07 Ford Powerstroke 6.0L Coolant Filtration System w/ Cat Filter

If you're working on your 2003-2007 Ford F-250 Super Duty with the 6.0L Powerstroke engine, keeping the coolant clean is a big deal. Over time, casting sand, metal shavings, rust, and mineral deposits can build up in your coolant. These contaminants can reduce your cooling system's efficiency and even damage critical parts like the water pump bearings, EGR cooler, and oil cooler.

This coolant filtration system from Sinister Diesel is designed to tackle those contaminants. The filter boss is CNC machined from solid billet 6061 aluminum and attaches to a bracket that uses factory mounting holes, so no drilling is needed. It includes high-strength silicone hoses with pre-assembled fittings that are factory tested for leaks. The kit comes with a genuine CAT coolant filter, known for its 99% efficiency at 50 microns, which is a solid option for keeping your coolant clean and extending the life of your cooling system components.

Replacing the filter is straightforward, and Sinister Diesel recommends replacing the first filter after 500 miles, then the next two at 3,000 miles each. After that, you can plan on replacing it annually. This bypass filtration system helps maintain optimal coolant flow while actively cleaning the coolant.
