This coolant filtration kit helps extend the life of your engine’s water pump, EGR cooler, and oil cooler by removing contaminants like casting sand and metal shavings. It filters small amounts of coolant while the engine runs and features a CNC-machined billet 6061 aluminum filter block that mounts without drilling. The kit includes all necessary fittings, and the filter is easily replaceable.
Removing contaminates such as the casting sand and metal shavings means your engine’s water pump, EGR cooler and oil cooler will last longer. This kit is designed to bypass and filter small amounts of the engine’s coolant while your diesel engine is running. The CNC machined billet 6061 aluminum anodized construction filter block attaches to a supplied bracket, which mounts to factory holes so no drilling is required. Filter block 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 changes, filter replacement can be done once a year. The silicone hoses fittings are pre-assembled for simple, leak-proof connections that factory tested at twice the recommended radiator cap pressure.
