To remove the exhaust manifold from a 1978 Oldsmobile, first, disconnect the negative battery cable and drain the coolant if necessary. Remove any components obstructing access, such as the heat shield or exhaust pipes. Loosen and remove the manifold bolts using a socket and ratchet, then carefully lift the manifold off the engine, taking care not to damage the gasket or surrounding components. Finally, clean the mounting surface on the engine block before installing the new manifold.
