    Q:
    What steps should be followed during the installation of the exhaust manifold for the 1989 Chevrolet C1500? Posted by Customer
    A:
    Installation is essentially the reverse of the removal procedure. Clean the manifold and head gasket surfaces to remove old gasket material, then install new gaskets. Do not use any gasket cement or sealer on exhaust system gaskets.
