(for vehicles without air conditioning)
Replace fuse
F01
.
Check fuse F01 from engine compartment. Is it good?
Replace water temperature sensor.
Replace the control relay of the cooling engine fan.
Replace the cooling engine fan assembly . Start the vehicle’s
engine.
Disconnect the water
temperature sensor. Is the
cooling engine fan working?
Check the control relay of the cooling engine fan Is it good?
Is any voltage between pins 1
and 2 of the cooling engine fan connector?
The wirin g
is
damaged. Fix it. Stop the vehicle engine.
Check the continuity and resistance
against vehicle mass between:
- pin B2 connector of water temperature sensor pin 13 UCE i njection;
- pin B1 connector of water temperature sensor pin 73 UCE i njection;
- pin 3 connector of cooling engine fan control relay exit fuse F01;
- pin 5 connector of cooling engine fan control relay pin 2 connector of
cooling engine fan

Cooling engine fan for vehicles with air conditioning
DISMOUNTIN G
Disconnect the battery (-) terminal.
Remove the air inlet pipe from the attachment of the battery screen.
Detach from clip the power steering oil reservoir from the battery screen.
Disconnect the engine fan connector ( 1)
Detach wiring from clips ( 2) and (3).
Disconnect the connector of the cooling engine fan resistance (4).
Carefully dismount the engine fan assembly from the radiator, from sustaining points (5).
REMOUNTING
Check the condition of the fan impeller and of the engine fan electric motor.
Carefully mount the engine fan assembly in the sustaining points (5).
Connect the connector of the engine fan resistance ( 4).
Connect the cooling engine fan connector ( 1) and attach it in clip (3) then in clip (2).
Attach in clips the power steering oil reservoir on the battery screen. Mount the air inlet
pipe.
Connect the battery (-) terminal. In case the vehicle is equipped with programmable
r adio-cassettes player, electronic clock, etc, there are t o be re-programmed before returning
the vehicle to the client. Check the engine fan operation: start the vehicle engine and disconnect the water
temperature sensor. The engine fan must start. Reconnect the water temperature sensor
then by means of the CLIP tester erase the memorized failure corresponding to the water
temperature sensor.

CL E ANING
It is very important not to scratch the surfaces for gaskets of the aluminum parts.
In order to dissolve the gasket particles stacked, product “ Decapjoint” is to be used.
A pply the product on the surfaces to be c leaned, leave it for a bout 10 minutes, then clean
using a wood palette knife. During performing this operation, use protection gloves.
REMOU NT I NG
The water pump sealing is ensured by means of LOCTITE 518 ; l ayer H, is 0.6 – 1 mm
thick and must be applied according to the bellow presented drawing. Remount the distribution belt (see chapter 11 “Distribution belt “).
Perform the cooling circuit filling and purging (see chapter “Filling – Draining”) .

COOLING - EXHAUST - TANKExhaust Assembly
ATTENTION !
Descending pipe in operation, may reach high temperatures and consequently must not
co me in contact with flammable materials which may lead to their auto-ignition.
Catalytic converter is to be mechanical shock protected.
DISMOUNTIN G
In order to di smount the noise a bsorber assembly ( 1), lift t he ve hicle on an elevator and
perform the following operation s:
Loosen the nuts ( 2) of the attachment collar between the expansion chamber ( 3) and the
noise silencer ( 1).
Di smount the thre e a ttachment e lastic supports of the noise a bsorber, on the carri age
body, rear pa rt. Release the noise silencer.
In order to dismount the assembled expansion chamber (3), perform the following operations:
Di smount the c ollar ( 4) and disengage the e xpansion chamber assembled with the de -
scending pipe.
Dismount the three elastic supports of the assembled expansion chamber.
Loosen the attachment collar nuts ( 2) and remove the assembled expansion chamber by
easy rotation and onward pulling.
In order to dismount the descending pipe assembly (6), perform the following operations:
Dismount the engine shield.
Dismoun t the catalytic converter attachment nuts ( 7) on the two studs of the exhaust manifold
flange. Dismount the attachment screws of the converter support ( 5).
For EURO 96, dismount the oxygen sensor located in upstream of the catalytic converter.
For EURO 00, dismount the oxygen sensors located in upstream, consequently, in
downstream of the catalytic converter.
Dismount the collar (4) and disengage the assembled catalytic converter from the assembled
expansion chamber.
Remove the descending pipe.
REMOU NT I NG
Perform the dismounting operations in the reverse order.
Ensure a perfect sealing between the exhaust assembly elements, using sealing paste Wurth,
on the joining area length (inside) between the noise absorber – expansion chamber (0.013 Kg);
The oxygen sensor gasket is to be replaced at each dismounting.
The tightening moment between noise absorber and expansion chamber is: 3.6 daNm.
The tightening moment of descending pipe attachment nuts on the exhaust manifold flange is:
2 daNm. Tightening moment between the catalytic converter and expansion chamber: 2.5 daNm.
All elements are to be assembled having the ambient temperature.

IMPORTANT:
During the int erventi on on the fuel tank
and on the fuel supply circuit, at t he working
place, do not smoke and do not bring near
an y incandescent parts.
Fuel tank draining i s not implying tank
dismountin g. The access is allowed through the
vehicle interior (trunk).
Dismo unt :
-tr unk carpet;
-v isitin g whole cover (by dismounting the
three attachment screws);
- disconnect the rapid coupling A;
- adjust to exit A, an enough long hose to
be introduced in a vessel outside the vehicle.
From the fuse box located inside the engine
compartment, remove the H relay of the petrol
pump and bridge across plugs 3 and 5 of the
relay connector, ensuring the petrol pump
working (12V).
Stop the pum p working when petrol
discontin uous draining s noticed.
Detach the plugs bridge.
Mount the petrol pump relay.

FILLING CAP
Fuel tank
The fuel tank is having a filling cap, sealed-type, with key. The filling cap for unleaded fuel has
a filler whole incompatible with a c lassical filling gun (lead has a negative effect upon the de-
pollution system : oxygen sensor and catalyst).
In case of vehicle overturning, the anti-overturning valve is getting blocked, avoiding in this
wa y, the petrol leakage towards the carbon can.

Lift the vehicle on a two columns elevator.
Dismount the four-attachment screws (6) of
the fuel tank on the carriage body, then maintained
in tilted position, disconnect the rapid coupling
on the anti-overturning valve ( 7).
D etach from clips collar ( 3) of the aerating
pipe on the upper filling cap.
Release the fuel tank together with the aerating
connection. Dismount the thermal screen ( 5) off the three
maintaining clips. Dismount the attachment clip ( 1) of the filling
cap muff on the lower filling cap.
Dism ount t he fue l pum p a sse mbly by
dismounting the attachment nut by means of the
MOT 1397 device.
REMOUNTIN G
Perform the dismounting operatio ns in the
reverse order. The t ightening moment of t he fuel tank
attachment screws on the carriage body is of
2.1 daNm and the tightening moment for fuel
pump assembly attachment nut, is of minimal
7daNm .
REMARK :
Collar (1) is for single use only.
When remounting, use a new click collar
