Add years of life to your Dodge Cummins 6.7 Liter diesel engine with this Water Coolant Filter Bypass System. Removing contaminates such as the casting sand and metal shavings (remnants left over from the casting and machining process when your Cummins was made), means your water pump, engine oil cooler, and EGR cooler (if equipped) will last longer. This kit is designed to bypass and filter small amounts of your Dodge or Ram coolant while your engine is running. The CNC machined billet 6061 aluminum anodized construction filter boss attaches to supplied bracket, which mounts to factory holes in your Dodge or Ram truck chassis. The filter boss includes 2 threaded inlet ports and 1 outlet port. This kit includes all fittings needed for installation. The filter can be easily unscrewed for replacement. We recommend replacement of the first filter at 500 miles with replacement of the second and third filters is at 3,000 miles each. After 3 filter changes, replacement can be done once a year. The silicone hose fittings are pre-assembled for simple, leak-proof connections and are factory tested at twice the recommended radiator cap pressure. The mounting bracket installs into factory holes. No drilling required. SKU: SD-COOLFilL-6.7C qualifies for free shipping!
