This Part of the Chapter is devoted to the repair of the V6 SOHC engine of the VG30E 3.0 l series, not related to the extraction from the car (in situ). The descriptions of most of the procedures under consideration are based on the assumption that the power unit remains in its regular place in the engine compartment of the car. In view of the above, if the engine has already been removed and installed on a workbench or mounting stand, many of the described steps should be omitted.
