Add filtration to help protect the cooling system and other vital engine components on your 1999-2003 Ford 7.3L Powerstroke. In most applications, a coolant filtration system installs easily into existing coolant hoses and constantly filters small amounts of engine coolant. Once installed, the coolant filter is able to catch and remove debris such as sediment, leftover casting sand, and other harmful contaminants that can clog oil coolers, EGR coolers, and damage other vital engine components. In most diesel pickup applications, these aftermarket filtration systems are typically installed as an add-on that use a "non-charged" coolant filter. This means that the filter does not contain any Supplemental Coolant Additives (SCA's) that are commonly found on HD and class 8 applications.
