2003 Mercury Sable Exhaust Manifold Parts Questions & Experts Answers

• Q: How to service the right exhaust manifold on 2003 Mercury Sable?

  A: The first step to access the right exhaust manifold service requires disconnecting the ground cable of the battery. Proceed with the job by first removing the cowl vent screen and cowl extension then disconnecting the Oxygen Sensor (HO2S) electrical connector. First remove the exhaust manifold to Exhaust Gas Recirculation (EGR) valve tube together with the exhaust manifold heat shield by dislodging the bolts. You need to remove the exhaust manifold bolts to disconnect the catalytic converter from the exhaust manifold. After that remove the six bolts securing the exhaust manifold to extract the assembly together with its exhaust manifold gasket which must be discarded. The exhaust manifold installation requires fitting an exhaust manifold gasket followed by manifold bolt tightening at two stages starting from 10 Nm (89 in. lbs.) and ending at 22 Nm (16 ft. lbs.). First connect the catalytic converter to its bolts before installing the exhaust manifold heat shield bolts along with the other bolts. Reconnect the HO2S electrical connector after you fix the exhaust manifold to EGR valve tube and you should complete the process by reinstalling the cowl vent screen and cowl extension before reconnecting the battery ground cable.
