The GMC 2500 Coolant Filtration System by Sinister Diesel is a high-performance upgrade designed for 2001-2010 Chevy/GMC 2500 and 3500 models equipped with a Duramax 6.6L engine. Crafted from CNC machined 6061 aluminum and anodized in the distinctive Sinister Blue, this filtration system provides a robust solution for protecting your engine’s vital components.

This Coolant Filtration System works by bypassing and filtering small amounts of coolant while the engine is running, effectively removing contaminants like casting sand and metal shavings. This ensures your engine's components such as the water pump, EGR cooler, and oil cooler last longer. The filter block, constructed with durability in mind, features two threaded inlet ports and one outlet port, simplifies replacement thanks to its easily unscrewable design. With installation requiring no drilling due to the use of factory mounting holes, you can easily fit this system using the included hardware and bracket.
