Sinister Diesel Coolant Filtration System SD-CF-6.7P-17 | RealTruck Top Pick

Even on a freshly rebuilt, or brand new engine, the coolant is usually contaminated with microscopic particles including casting sand leftover from the manufacturing process, metal shavings, rust, and mineral deposits, all of which can diminish the cooling system’s ability to absorb heat. If these particles are left inside the engine, they can actually cause premature wear to the bearings inside your water pump and cause expensive damage to the small passages inside your EGR cooler and oil cooler. With the Sinister Diesel Coolant Filtration System you can be sure your cooling system is working at maximum efficiency for a long time to come.

The Sinister Diesel Coolant Filtration System is designed to bypass and filter small amounts of the engine’s coolant while your diesel engine is running. The filter block is constructed from anodized aluminum and attaches to a supplied bracket, which mounts to factory holes so that no drilling is required. The filter block includes two threaded inlet ports and one outlet port, and includes all fittings needed for installation. The silicone hose fittings are pre-assembled for simple, leak-proof connections that are factory tested at twice the recommended radiator cap pressure.

The Sinister Diesel Coolant Filtration System comes with either a WIX or CAT Coolant Filter that can be easily unscrewed for replacement. And it is recommended that the first filter be replaced at 500 miles, with replacement of the second and third filters at 3,000 miles each. After 3 changes, the filter can be replaced once a year. Additionally, these coolant filtration systems are covered against manufacturer defects for one year.
