Remove and Inspect High Pressure Turbocharger Assembly
IMPORTANT: Follow all cautions, warnings, and notes in the Electronic Service
Manual (ESM) when working on or near the fuel system, turbocharger system, and all
parts and components related to the repair procedure in this bulletin.
CAUTION:


Cover the surrounding areas of the engine bay with suitable protection to avoid
damage to paint and all other surrounding exterior parts.



When removing components such as hoses, tubes, fuel lines, etc., be sure to cap,
plug, or tape these openings to prevent fluid from spilling or debris from entering.
 Refer to special tools J-54423 and J-54427 for caps, plugs, and tape (see page
2).
 The caps and plugs can be reused. Make sure to put them back in the kits when
they are not needed.
 When told to use tape, use the tape supplied in kit J-54423 only. When removed,
this tape does not leave a residue. Tape residue may cause leaks.

1. Clean all loose dirt and debris from the engine bay area and wherever work is to be
performed with 30 psi maximum compressed air.
WARNING: Wear appropriate eye protection and protective clothing. Failure to use
protective wear and/or operating compressed air above 30 psi may increase the
possibility of physical injury.

2. Record all audio presets.
