Protect the cooling system in your 2007.5-2012 Dodge Ram 2500 or 3500 with the Sinister Diesel SD-COOLFIL-6.7C-W 6.7L Cummins Coolant Filtration System. Coolant can contain casting sand, metal shavings, rust, and mineral deposits, even in a new or freshly rebuilt engine. These contaminants can reduce heat-transfer performance and contribute to premature water-pump bearing wear or damage to the narrow passages in the EGR and oil coolers. This kit continuously helps remove damaging particles so the cooling system can operate more efficiently over time.
The Sinister Diesel coolant filter kit includes a CNC-machined 6061 billet aluminum filter block, blue anodized finish, mounting bracket, silicone hoses, pre-assembled hose fittings, WIX coolant filter, and all necessary installation hardware. The filter boss features two threaded inlet ports and one outlet port for flexible routing. Installation requires no drilling because the mounting bracket uses factory mounting holes, helping simplify the installation while maintaining a clean, professional appearance in the engine compartment.
The first filter replacement is recommended after 500 miles. Replace the second and third filters after 3,000 miles each, then change the filter annually after the initial service interval. The system can also be upgraded to a CAT coolant filter. Manufactured and tested by Sinister Diesel in California, part number SD-COOLFIL-6.7C-W is designed for 2007.5-2012 Dodge Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine. Verify vehicle application before ordering.
