Removing and installing intake manifold (bottom section)
Use bit -3320/2- to remove and install securing bolt -arrow-.
  Note
t  If you only want to remove the the bottom section of the intake manifold, make sure the injectors remain in the cylinder head. If necessary, have a second mechanic hold the injectors in position.
t  Reason: If the injectors are removed, the combustion chamber ring seals and the support ring must be renewed.
