    Q:
    What should be done after disconnecting the exhaust pipe and other components when removing Exhaust Manifolds for the 1986 Buick Century? Posted by Verified Customer
    A:
    After disconnecting the exhaust pipe and other components, the next step involves bending back any locking tabs on the mounting nuts, soaking them with solvent, and then loosening and removing them. This allows for the removal of the manifold and seal. It's also crucial to ensure that the block's surface is thoroughly cleaned.

Remove the generator or air conditioning brackets where they attach to the exhaust manifold. 4. Disconnect the exhaust pipe where it connects to the exhaust manifold flange, using penetrating oil if needed. 5. Pry back the metal retainers from the bolt heads. 6. Remove each of the bolts securing the exhaust manifold. 7. Remove the manifold from above, noting that on some late models it may be necessary to disconnect the intermediate shaft of the steering column for better access.
