Engineered specifically for 2003 through 2007 Ford F-250, F-350, F-450, F-550 Super Duty and Excursion trucks equipped with the 6.0L Powerstroke diesel engine, the Genuine Ford EGR Cooler Installation Gasket Kit (3C3Z-9433-AB) provides all mandatory factory seals required whenever servicing or replacing the exhaust gas recirculation cooler. Reusing compressed, heat-baked factory gaskets during an EGR cooler swap is a primary cause of stubborn exhaust leaks, soot blow-by, and coolant loss under under-hood pressurization.

As a complete original equipment kit, the 3C3Z-9433-AB package includes precision-molded coolant seals, high-temperature exhaust gaskets, and mounting hardware engineered by Ford Motor Company to match exact thermal expansion rates and sealing pressures. Utilizing authentic Ford components eliminates the fitment inconsistencies and premature seal blowouts common with generic aftermarket gasket sets.

• Fitment Notice: Compatible with both early round-cooler (2003–mid 2004) and late square-cooler (late 2004–2007) 6.0L Powerstroke setups. Always verify that all old gasket material is completely scraped off the mounting surfaces before installing the new seals.
• Installation Tip: Clean all mating surfaces on the intake manifold and exhaust up-pipe thoroughly. Lightly coat coolant O-rings with clean coolant or clean engine oil during installation to prevent pinching or binding as the cooler and up-pipe are torqued down.
