STARTING-CHARGING
Alternator
16
REMOVAL
Place the vehicle on a two post lift .
Disconnect the battery as well as all electrical
connections leading to the alternator.
Remove :
- the alternator belt and that of the power as-
sisted steering pump for the D7F engine (if
fitted),
- the alternator.
REFITTING
Refitting is the reverse of removal.
D7F Engine
Tensioning of the alternator belt is carried out
using the locally manufactured tool shown be-
low (threaded rod 100 mm in length (X) and three
M6 nuts).
D7F / E7J
Engines
SPECIAL TOOLING REQUIRED
Mot. 1273 Tool for checking belt tension
10617R
E7J Engine
Tension the belt using the bolt at (1) and tighten
the nut at (2) , having measured the tension.
13363R
See section 07 "Accessories belt tension" for the
tension values.

SPECIAL NOTES FOR MULTIPOINT INJECTION
• 35 track SAGEM or MAGNETI MARELLI computer for vehicles without options.
• 55 track SAGEM computer ,
SAFIR or MAGNETI MARELLI type for versions with air conditioning.
•Semi-sequential multipoint injection. Injectors controlled two by two (injectors for cylinders 1 and 4 fol-
lowed by injectors for cylinders 2 and 3).
•Semi-static ignition with dual single unit coils.
•Canister bleed solenoid valve controlled by RCO signal.
•Computer configuration depending on gearbox type (manual gearbox or automatic transmission).
•The maximum engine speed permitted is 6 200 rpm.
•Idle speed correction depending on :
- battery voltage,
- air conditioning
- power assisted steering pressostat.
•Injection warning light on instrument panel not operational.
•Use fault finding fiche n° 27. D7F Engine
FITTING A 2ND GENERATION ENGINE IMMOBILISER REQUIRES A SPECIAL PROCEDURE FOR REPLACING THE
