SAFETY REQUIREMENTS: HDi DIRECT INJECTION SYSTEM
Engines: HDi ALL TYPES
CLEANLINESS REQUIREMENTS.
Preliminary operations.
IMPERATIVE: The technician should wear clean overalls.
Before working on the injection system, it may be necessary to clean the apertures of the following sensitive components:(refer to corresponding procedures) Fuel filter.
High pressure fuel pump.
High pressure fuel injection common rail. High pressure fuel pipes
Diesel injector carriers.
IMPERATIVE: After dismantling, immediately block the apertures of the sensitive components with plugs, to avoid the entry of impurities.
