Ford BT4Z-5G232-C Exhaust Manifold And Catalyst Assembly

Before beginning this procedure, allow the engine to cool completely and apply penetrating oil to the manifold and converter fasteners. On 2.7L engines, the exhaust manifold is integrated into the cylinder head, and the turbochargers bolt directly to the cylinder heads. For 2011 through 2014 3.5L and 3.7L models, the front exhaust manifold and the catalytic converter are integrated into one piece, while in 2015 and later 3.5L models, both exhaust manifolds are integrated with the catalytic converters. To remove the front exhaust manifold, disconnect the cable from the negative battery terminal, disconnect the electrical connector for the oxygen sensor and the catalytic converter monitor, and on 2015 and later models, remove the cooling fan shroud assembly. Raise the front of the vehicle and support it securely on jackstands, then disconnect the exhaust Y-pipe from below. Remove the heat shield over the front exhaust manifold, discard the six nuts securing the exhaust manifold, and remove the manifold and converter. Extract the exhaust manifold studs using a stud holding tool or a pair of nuts tightened together over a stud, and discard them. Use a scraper to remove all old gasket material and carbon deposits from the manifold and cylinder head mating surfaces, being cautious not to gouge the aluminum engine parts. Install new exhaust manifold studs with light oil on the threads, place a new manifold gasket over the studs, and install the manifold with new self-locking nuts. Tighten the nuts, starting with the center fasteners and working towards the ends, to the specified torque, and complete the installation in reverse order. For the rear exhaust manifold, disconnect the cable from the negative battery terminal and the connector to the rear bank oxygen sensor, then raise the vehicle and support it securely on jackstands. Remove the Y-pipe-to-catalytic converter flange nuts and disconnect the Y-pipe, and for 2014 and earlier models, remove the rear-bank catalytic converter. Discard the six exhaust manifold mounting nuts and remove the manifold from the engine, along with the manifold gasket. Extract the exhaust manifold studs and discard them, then scrape off all gasket material and carbon deposits from the mating surfaces, taking care with aluminum parts. Install new exhaust manifold studs with light oil on the threads, place a new manifold gasket over the studs, and install the manifold with new self-locking nuts. Tighten the nuts, starting with the center fasteners and working towards the ends, to the specified torque, and complete the installation in reverse order.

To replace the catalytic converter in four-cylinder engines, start by raising the vehicle and placing it securely on jackstands. Locate and disconnect the downstream oxygen sensor on the upper central part of the catalyst. Unscrew and remove the downstream oxygen sensor/catalyst sensor from the catalyst. Loosen the fasteners on the clamp that secures the front end of the catalyst to the turbocharger. Remove the nuts and bolts that secure the flange at the rear end of the catalyst to the exhaust pipe. Remove the catalytic converter and discard the old gasket between the exhaust down pipe and the catalyst mounting flange. Installation is the reverse of removal, using a new gasket and new fasteners if necessary.
