NOTE: Before installing the upper intake manifold, the EGR port must be clean and free of obstruction. Use combustion chamber cleaner and a suitable wire brush to remove carbon buildup from the EGR passages. Clean and inspect all surfaces. Install new seals and new gaskets. Use Metal Surface Cleaner F4AZ-19A536-RA or equivalent meeting Ford specification WSE-M5B392-A to clean the upper and lower intake manifold gasket surfaces. Position the upper intake manifold gasket on the fuel injection supply manifold. 2. Position the upper intake manifold and install the six nuts.
