• Q: How to replace the left exhaust manifold on 2001 Chevrolet Lumina?

  A: The first step for replacing the left Exhaust Manifold requires users to detach the battery ground cable. The work starts by taking off the throttle body air inlet duct after which you should handle the right engine mount strut bracket. Begin by removing the exhaust crossover pipe heat shield after which you should unfasten the bolts that secure the crossover pipe to the left hand Exhaust Manifold. Secondly disconnect the bolts securing the left hand Exhaust Manifold heat shield before removing both the heat shield and the manifold with its installed nuts. The procedure requires removal of the left hand Exhaust Manifold Gasket while both the left hand Exhaust Manifold surface and left hand Cylinder Head need thorough cleaning. Position the new left hand Exhaust Manifold Gasket after which you should install the left hand Exhaust Manifold into place. Tighten all left hand Exhaust Manifold nuts to 16 nm (12 ft. Lbs.) before installing the left hand Exhaust Manifold heat shield and securing it through bolt torques set to 10 nm (89 inch lbs.). You should install the bolts which will attach the exhaust crossover pipe to the left hand Exhaust Manifold followed by installation of the exhaust crossover pipe heat shield. After installing the throttle body air inlet duct and the right engine mount strut bracket users need to finish their work by reconnecting the battery ground (negative) cable.
