This kit is designed to bypass and filter small amounts of coolant while your Ford Powerstroke engine is running. The CNC machined billet 6061 aluminum anodized construction filter head attaches to supplied bracket, which mounts to factory holes in your Ford trucks chassis. The filter boss includes 2 threaded inlet ports and 1 outlet port. This coolant bypass kit includes all fittings needed for installation. We recommend replacement of the first filter at 500 miles. 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. Mounting bracket installs into factory holes. No drilling is required.
