   • Disconnect any sensors or pipes attached to the manifold.
   • Remove the bolts and nuts securing the manifold to the engine cylinder head and the downpipe.
   • Carefully remove the old manifold and gaskets. Inspect the cylinder head surface for damage or corrosion.
3. Installation of New Manifold:
   • Clean the mating surfaces on the cylinder head and downpipe thoroughly.
   • Position the new gaskets onto the cylinder head studs.
   • Carefully place the new Dorman 674-250 exhaust manifold onto the studs.
   • Install the new nuts and bolts, tightening them finger-tight initially.
   • Connect the manifold to the downpipe using the provided hardware and new gasket.
