How to remove and replace the right-hand exhaust manifold on Ford Flex?

The removal process for the right-hand (RH) exhaust manifold demands initial steps of catalytic converter extraction and disconnected Heated Oxygen Sensor (HO2S) electrical connection. The next step requires you to detach six nuts holding the RH exhaust manifold in place while discarding the nuts as well as the gasket. Begin by cleaning the RH exhaust manifold followed by a stud removal process of its six components which leads to disposal. The sealing surfaces require cleaning with a plastic scraper from which metal scrapers and wire brushes and abrasive tools must be avoided due to their potential to create leaking defects. Follow the packaging instructions to perform metal surface prep on the exhaust manifold mating surface of the cylinder head. Follow this installation procedure by using six new RH exhaust manifold studs that need to be tightened to 12 Nm (106 lb-in). The process of exhaust leak prevention requires two-stage torque tightening of new exhaust manifold nuts beginning with a torque of 20 Nm (177 lb-in) followed by a torque of 25 Nm (18 lb-ft). Install the RH exhaust manifold first using a new gasket before the torque sequence starts. The RH HO2S electrical connector needs to be restored while the RH catalytic converter must be installed.
