【Efficient "T" Port Design for Dual Flushing】 Our coolant flush kit features a unique "T" port adapter, allowing simultaneous connection to both air and water hoses for thorough back-flushing. This design ensures optimal cleaning of factory EGR coolers or trucks with off-road EGR delete kits, preventing costly engine damage and maintaining peak performance. 【Reusable & Cost-Effective Solution】 Crafted from durable aluminum and brass, this oil flush is built to last. Reuse it multiple times without leaving any parts on the vehicle, saving you money compared to replacement coolers or professional servicing. Ideal for DIY enthusiasts and mechanics. 【Prevents Leaks with Included Teflon Tape】 For a secure, leak-free connection, we include high-quality Teflon tape. Wrapping the adapter threads ensures a tight seal during the flushing process, preventing leaks and guaranteeing an efficient, mess-free clean. 【Easy Installation】 Drain the cooling system, attach the flush adapter to the manifold cover (using the provided Teflon tape), and connect your garden hose. Flush until water runs clear—no complex tools or permanent modifications needed. 【Wide Compatibility for Ford Diesel Models】 Compatible with: 2004-2005 Ford E - 350 Club Wagon, 2004-2010 Ford E-350 Super Duty, 2004-2010 Ford E - 450 Super Duty, 2003-2007 Ford F -250 Super Duty, 2003-2007 Ford F - 350 Super Duty, 2003-2007 Ford F -450 Super Duty, 2003-2007 Ford F-550 Super Duty, 2004-2008 Ford F650, 2004-2008 Ford F750, 2003-2005 Ford Excursion, 2003-2010 Ford 6.0L Diesel (VT365/VT275).
