SPECIAL NOTES FOR VEHICLES FITTED WITH
DRIVER’S AIR BAG
WARNING
In order to avoid any risk of damage to the rotary
switch beneath the steering wheel, the following
instructions should be followed:
• Before disconnecting the steering column from
the rack, the steering wheel MUST be immobi-
lised with the wheels straight with the aid of a
"steering wheel lock" throughout the opera-
tion.
• If there is any doubt about the rotary switch
being properly centred, the steering wheel
must be removed in order to apply the centring
method described in the Technical Note cove-
ring the 2nd generation air bag.
REMINDER: this kind of work must only be carried
out by properly trained and qualified staff.
Remove:
- both the sub-frame reinforcements,
- the earth strap mounting bolt on the body
side,
- the exhaust downpipe nuts. D7F engine

DIESEL EQUIPMENT
General
13
The use of electronic injection in Diesel engines has allowed the operational power of these engines to be
optimised, thus reducing the emission rate of pollutant gases.
The system consists of a computer, which receives information from:
- the coolant temperature sensor,
- the air temperature sensor,
- the engine speed sensor,
- the vehicle speed sensor,
- the load potentiometer,
- the injection start sensor, which forms part of the injector of cylinder n° 3 (injector with sensor).
It controls :
- the injection pump :
• the altimetric corrector (F8Q 630) via a relay
• the advance solenoid valve.
- the cold engine starting system (heater plugs and pre-postheating unit),
- the exhaust gas recycling system (EGR),
- the diesel injection fault warning light,
- the preheating warning light,
- the solenoid valve controlling the fast idle speed LDA,
- the relay controlling the power assisted steering electric pump assembly (for vehicles with air conditio-
ning), the pump assembly is supplied once the engine speed exceeds 650 rpm.
It carries out a self diagnosis procedure which may be visualised through the
XR25.
SPECIAL FEATURES
On the injection pump it is possible to replace:
- the load potentiometer,
- the advance solenoid valve,
- the altimetric corrector,
- the electrical solenoid.

that replacement values are used to ensure engine operation.

COOLING
Filling and bleeding
19
There is no heater matrix water control valve.
Water flow is continuous in the heater matrix,
which contributes to the cooling of the engine.
FILLING
Check the tightening of the drain plug(s).
Open the two bleed screws.
Fill the circuit through the opening in the expan-
sion bottle.
Tighten the bleed screws as soon as the liquid
flows in a continuous jet.
Start the engine (2 500 rpm).
Adjust the level by overflow for a period of about
4 minutes .
Close the bottle.
BLEEDING
Allow the engine to run for about 10 minutes at
2 500 rpm, until the fan(s) operate (time necessary
for automatic degassing).
Check the liquid level is at the "Maximum" mar-
ker.
DO NOT OPEN THE BLEED SCREWS WHILST THE
ENGINE IS TURNING.
RE-TIGHTEN THE EXPANSION BOTTLE CAP WHILST
THE ENGINE IS WARM.
