  9. If not equipped with a turbocharger, disconnect the exhaust manifold from the exhaust pipe.
  10.  
  11. If equipped with a turbocharger, perform the following procedures:
    1. Disconnect the intake and exhaust hoses from the turbocharger.
    2.  
    3. Disconnect the oil lines from the turbocharger.
