2008 Lincoln MKX Exhaust Manifold Parts Q&A

• Q: How to service and repair the LH exhaust manifold on 2008 Lincoln MKX?

  A: You should start the LH exhaust manifold repair by eliminating the LH catalytic converter together with the LH heated oxygen sensor (HO2S). Start by removing the 3 bolts holding the LH exhaust manifold heat shield before you detach the 6 nuts securing the LH exhaust manifold. Discard both elements with the nuts and gasket. The LH exhaust manifold receives cleaning and inspection before the technician discards the 6 LH exhaust manifold studs. It is essential to clean the cylinder head exhaust manifold mating surface with plastic scrapers using the metal surface prep as detailed in the packaging instructions. Using metal scrapers or wire brushes is dangerous because they might damage the sealing surfaces. For installation you must install six new LH exhaust manifold studs before tightening them to 12 Nm (9 lb-ft). You must repeat exhausting the exhaust manifold nuts according to specifications because this step prevents leakage from occurring. New nuts along with a fresh gasket enable the correct installation of the RH exhaust manifold which requires a two-step torque procedure starting at 20 Nm (15 lb-ft) then reaching 20 Nm (15 lb-ft) in the second stage. Athite the new LH exhaust manifold heat shield in place through its 3 bolts until they reach 14 Nm (10 lb-ft) torque specifications followed by placing the LH HO2S and LH catalytic converter installation.
