2008-2010 F250 & F350 6.4L Sinister Diesel Coolant Filtration System SD-COOLFIL-6.4-W

Filters out Coolant Contaminants for Improved Reliability and Cooling

Ford's 6.4L Powerstroke is known for dirtying up its coolant in relatively short amounts of time, which leads to ineffective cooling capabilities, a loss of performance, and less reliability for your water-cooled engine components. Sinister Diesel's 6.4L Powerstroke Coolant Filtration System can change all that by giving your aggressive Super Duty build a way to keep its coolant clean to improve the reliability and performance of your entire Powerstroke V8. Sinister's coolant filtration system adds a coolant filter to your truck using high-quality components and coolant lines so that your truck's engine coolant stays absolutely pristine. The kit comes with everything you need to drop it into your truck's engine bay and get it up and running in a relatively simple bolt-on installation.

High-Quality Billet Aluminum with Silicone Hoses

The Sinister Coolant Filtration System is a complete coolant filter kit that taps right into your Super Duty's factory cooling system and efficiently filters your truck's coolant without causing a loss in coolant flow or causing other problems. The kit bypasses a small amount of engine coolant at a time over to the kit's filter and pulls out any contaminants. The filtration system is built around a filter boss made from CNC machined 6061 billet aluminum that attaches to a complete mounting bracket that bolts into existing holes in your truck's body. Coolant is fed into the filter and returned to your truck's cooling system using pre-cut silicone lines with high-quality fittings that help prevent leaks and are durable enough for just about any application.

Filter Change Interval: Sinister Diesel recommends changing the first filter out at 500 miles, the next three filters at 3000 mile intervals, and all changes after that just once a year in order to filter out initial contamination.
