2003-2007 F250 & F350 6.0L Sinister Diesel Coolant Filtration System SD-COOLFIL-6.0-W

Helps Clear Coolant Contaminants for More Efficient Operation and Reliability

One of the many flaws of the 6.0L Ford Powerstroke V8 was its tendency to dirty up its coolant with metal shavings left over from manufacturing as well as gunk that manages to spill over from the EGR system, which naturally means that the truck's cooling efficiency is greatly lowered which means that the lifespan of any water-cooled parts of the engine were greatly effected. That's where Sinister Diesel's 2003 to 2007 Super Duty 6.0L Coolant Filtration System comes in. This complete kit adds a coolant filter to your truck's cooling system which pulls out contaminants and allows for more reliable engine operation and a longer lifespan of your EGR system, water pump, and oil cooler, making it an excellent upgrade for practically any 6.0L Super Duty truck.

Complete Kit with Filter Head, Bracket, Lines, and Fittings

The Sinister Diesel Coolant Filter Kit comes with everything you need to to get the system up and running, and features a relatively simple bolt-on design. The kit is built around a CNC machined 6061 billet aluminum filter head with a blue anodized finish that accepts Wix coolant filters. The head bolts into your truck with a supplied bracket that uses pre-existing holes in your truck's body. The filter boss has two threaded inlet ports and a single outlet port that feeds a small amount of your truck's coolant to the filter at a time so that there's not interference with your engine's operation. The kit comes standard with lines and high-quality fittings that help ensure a leak-free operation.

Filter Change Interval: Sinister recommends changing your first filter after 500 miles, the next three filters at 3,000 miles each, and then just once a year afterwards to ensure contaminants currently in your coolant are proper purged.
