WARNING
• Fuel is highly flammable.
Do not handle it near flames or
heat.
• Spilled fuel may catch fire and
therefore, must be wiped off com-
pletely.
CAUTION
• The harnesses and connectors between the injectors and common rail electronic control unit are under
high voltage. Be careful not to receive an electric shock. Before attempting to remove the injectors, turn
the starter switch to the LOCK position.
• Carefully handle the injector, taking care not to damage the threaded portion and nozzle as high pressure
is applied to the injector.
• To eliminate fuel injection and other problems, protect the injectors and pipes, that have been removed,
from the ingress of contaminants.
• Contact Bosch Service Station for any service needs of the injector.
Installation sequence
Follow the removal sequence in reverse.
CAUTION
• Do not attempt to clean the nozzle hole with a wire brush or other similar tools, or the hole can be dam-
aged.
• Be sure to tighten the nozzle bridge bolts to the specified torque. Overtightening the bolts can deform the
injectors, resulting in incorrect fuel injection.
