Whether your engine is brand new or has had a long service life, contaminants like metal shavings, rust, mineral deposits and casting sand can diminish the heat capacity of your Jeep’s cooling system. Over time, these dangerous deposits can cause damage to your water pump bearings and small passages. The CNC machined billet 6061 aluminum anodized construction filter block attaches to a supplied bracket that mounts to factory holes. No drilling is required. This kit includes all of the fittings needed for installation. The filter unscrews quickly, making replacement quick and simple. We recommend replacement of the first filter at 500 miles and replacement of the second and third filters at 3,000 miles each. After three changes, filter replacements can be replaced once a year. The silicone hose fittings come pre-assembled to ensure pure, leak-proof connections. These connections are factory tested at twice the recommended radiator cap pressure to provide unsurpassed reliability.
