2008 Lincoln Mark LT Exhaust Manifold Parts Questions & Experts Answers

• Q: How to service the right-hand exhaust manifold on 2008 Lincoln Mark LT?

  A: The service operation of right-hand exhaust manifold requires starting with a hoisted vehicle in neutral gear position. Start the procedure by uninstalling both the starter and the right-hand inner fender well. Then detach the two nuts which fasten the exhaust manifold to the catalytic converter and tighten the new nuts to 40 Nm (30 lb-ft) during installation. The servicing operation requires first lowering the sway bar after removing the four bolts and applying a 30 Nm (22 lb-ft) torque during reinstallation. The installation requires new exhaust manifold nuts assuming the removal of eight old nuts followed by proper tightening of the new nuts to 25 Nm (18 lb-ft) based on a certain sequence. As part of the installation process replace all eight exhaust manifold-to-cylinder head studs while discarding the older pieces and using 12 Nm (9 lb-ft) torque settings for tightening them. You should throw away the gaskets from the right-hand exhaust manifold before cleaning the sealing areas with a plastic scraper and metal surface prep which must exclude any abrasive tools that might lead to damage. Examine the exhaust manifold surface flatness as the first step before you reinstall the new components according to the reverse removal procedure.
