Ford 8S4Z-5G232-C Exhaust Manifold And Catalyst Assembly

A substantial loss of power may indicate a blocked converter, which may require replacement.

Remove the nuts and detach the exhaust manifold and gasket, taking care not to damage vulnerable components. For additional clearance, unscrew the studs from the cylinder head using a female Torx-type socket if necessary.

To install the intake manifold on models through 2004, follow these steps. Clean the mating faces of the intake manifold and cylinder head. Use new gaskets during installation. Tighten the nuts/bolts to the specified torque. Once the engine is fully warmed-up, check for signs of fuel, intake, or vacuum leaks. Test the vehicle and check for proper operation of all disturbed components.
