How to service the LH exhaust manifold on 2003 Ford F-150?

Service of the LH exhaust manifold begins with removing the oil level indicator tube followed by its nut before discarding the O-ring seal. Start by disconnecting the battery ground cable while hoisting the vehicle in the air. The first step requires removal of the LH Heated Oxygen Sensor (HO2S) electrical connector and subsequent disconnection of the two Y-pipe nuts from the exhaust manifold. Take out the LH exhaust manifold and its gasket by removing the two nuts which secure the engine lifting eye while discarding the gasket afterward. Follow the installation process by securely tightening the nuts according to their specified sequence and use the reverse order of the removal process.
