Sinister Diesel 03-07 Dodge 5.9L Cummins Coolant Filtration System w/ Wix Filter

The 5.9L Cummins engine in your 2003-2007 Dodge Ram 2500 or 3500 can benefit from cleaner coolant. This kit from Sinister Diesel is designed to remove microscopic particles like casting sand, rust, and metal shavings that can get into your cooling system. These contaminants can cause premature wear on your water pump bearings and clog the small passages in your EGR and oil coolers, leading to expensive repairs.

This kit features a filter block machined from 6061 billet aluminum, which includes threaded inlet and outlet ports. It comes with abrasion-resistant hoses and a mounting bracket that installs into factory holes, so no drilling is required. The system includes a WIX coolant filter, and Sinister Diesel recommends replacing the first filter after 500 miles, the next two after 3,000 miles each, and then annually thereafter. This setup helps ensure your cooling system operates at maximum efficiency for years to come.
