2006 Lincoln LS Exhaust Manifold Parts Questions & Experts Answers

• Q: How to service the left-hand exhaust manifold on 2006 Lincoln LS?

  A: Start the left-hand exhaust manifold service on the vehicle through hoisting with the transmission set to neutral position. A proper holding mechanism should be used to stabilize the steering wheel in a straight-ahead position before disconnecting the intermediate shaft to avoid Clock Spring damage. Begin by removing the catalytic converters and next step should be to loosen the intermediate shaft slider bolt. You must disassemble the intermediate shaft from the steering gear using one intermediate shaft-to-steering gear bolt for discarding purposes. Start by taking out the oil level indicator tube followed by removing screws and slash shield at the lower left-hand side. Start by removing four heat shield bolts before proceeding to unscrew eight nuts to separate the exhaust manifold. Keep all nuts for disposal. Reset the heat shield stud bolt before discarding the exhaust manifold gasket and then remove and discard all eight exhaust manifold studs. Thoroughly examine the exhaust manifold components before assembling the gasket. Begin by mounting eight new exhaust manifold studs and secure them at 19 Nm (14 ft. lbs.) torque before adding the new exhaust manifold gasket and the heat shield stud bolt that requires 50 Nm (37 ft. lbs.) torque. Use eight new nuts to fasten the exhaust manifold tonight each one to 25 Nm (18 ft. lbs.) according to the designated sequence. Follow the heat shield installation by using four bolts which must be tightened to 3 Nm (27 inch lbs.). Then reinstall the lower left-hand splash shield and screws followed by the oil level indicator tube. Install a new intermediate shaft-to-steering gear bolt before tightening it to 35 Nm (26 ft. lbs.) followed by intermediate shaft slider bolt tightening to an equivalent torque. Finally, reinstall the catalytic converters.
