REMOVAL & INSTALLATION



It is always advisable to purchase new parts before proceeding with a job. Exhaust gaskets and down pipe gaskets can be purchased separately if need be. If you are planning on doing more than this procedure, a head set, which comes with all gaskets will do just as good. It is also advisable to look at the engine to see if while you are doing a job, you may need to replace a hose or wire that could be damaged. Even though it may not pertain to the current procedure, it can't take but a minute to fix another problem about to occur.

V6 and V8 Gasoline Engines

See Figures 1, 2 and 3

  1. Disconnect the negative battery cable.
  2.  
  3. Disconnect the exhaust manifold at the flange where it mates to the exhaust pipe.
  4.  
  5. If the vehicle is equipped with air injection and/or a carburetor-heated air stove, remove them.
  6.  
  7. Remove the exhaust manifold by removing the securing nuts, washers and screws. To reach these pieces, it may be necessary to jack the engine slightly off its front mounts. When the exhaust manifold is removed, sometimes the securing studs will screw out with the nuts. If this occurs, the studs must be replaced with the aid of sealing compound on the coarse thread ends. If this is not done, water leaks may develop at the studs.
