FILLING AND DRAINING
The hea ting radiator does not have a tap.
The circula tion of the cooling liquid is done continuosly within the heating radiator, which con-
tributes to the heating of the engine.
F
ILLING
The tightening of the emptying stopper is checked.
Th e dr aining screw placed on the tube between the engine and the air-conditioning radiator is
taken off.
Th e circ uit is filled through the hole of the de-gassing pot.
The dr aining screw is fastened when the liquid flows in a continuous jet.
The engine is set into motion ( 2500 rot/min).
The leve l is adjusted for approx. 4 minutes.
Th e stopper of the de-gassing pot is closed.
D
RAINING
The engine is let to run for 10 minutes at 2500 rot/min until the motor-ventilator starts (i.e. the
time for the automatic de-gassing).
Check if thelevel of the liquid is close to “ Max”.
Do not open the draining screw when the engine is running.
Fasten again the stopper of the de-gassing pot with the engine still hot.

1. CHECKING WATERTIGHTNESS OF CIRCUIT
The MS 554-01 adapter is mounted instead of the valve of the de-gassing pot.
The MS 554-07 device is connected to the adapter.
The engine is heated, and then stopped.
the pump is used in order to put the circuit under pressure. The pumping is stopped at a value 0.1 bar smaller than the tare value of the valve ( 1.2 bar).
Th e pr essure must not go down; otherwise, the leak is looked for.
Th e junction of the device for cooling system decompression is progressively unscrewed,
then the apparatus is taken off and the valve of the de-gassing pot, equipped with a new fitting,
is mounted.
2. CHECKING WATERTIGHTNESS OF CIRCUIT
The MS 554-06 devi ce, then the pressure in the circuit is reestablished; this pressure must
become stable at the tare value of the valve with the control tolerance of +/-0.1 bar.
Th e tare value of the valve of the de-gassing pot: 1.2 bar.

DISMONTING
The battery is disconnected.
The tube s of the radiator are stopped up with the MOT 453 de v i ce s .
Dismount the hoses from the radiator by means of the elastic collar pliers MOT 1202-01.
The two screws of the stand are taken off the upper traverse of the radiator and the radiator
is taken off. The radiator is emptied and the cooling liquid is retrieved.
R
EMOUNTING
Check the existence of the supporting bushings.
The radiator is mounted.
The jack s for the fixing on the radiator are mounted, as well as the radiator stands, and the
fixing sc rews are fastened (0,57 daN).
The MOT 453 devices are taken off.
The tube s that have been taken off are mounted back and the collars are tightened.
Note : When mounting, line up the marks from the hoses and the related parts.
The ba ttery is connected.
Th e filling and the draining of the cooling circuit is done.
Tightening moments:
- the screws for the radiator stands (M6- 2 pieces) - 0,57 daN.

DISMOUNTING
Di
sconnect the (-) plug of the battery.
Di sconnect the cooling fan connector (5).
Di sconnect the cooling fa n resistance connector (1). Mark t he mounting position iden-
tification of the two connectors.
Detach the wiring from clip (6).
Cut the clip attaching the wiring on the cooling fan assembly in point (7).
Dismount the four-attachement screws (3) of the cooling fan on the radiator, recovering the
washers (2) and (4). Remove the cooling fan assembly.
REMOUNTING
Check the condition of the fan propeller, cooling fan electri c motor, washers.
Tighten the attachement screw (3) of the assembly.
Replace the clip from point (7).
Mount the wiring of t he cooling fan assembly taking i nto the considera tion the mount-
ing position m arked before dismounting. This is to be fi xed by means of a clip in point (7)
and will pass trough the clip (6). Connect the cooling fan re sistance connector (1).
Connect the cooling fan c onnector (5). Observe t he m ounting position i dentification of
the two connectors. Connect the battery plug (-). In case the vehicle is equipped with progammable radio-
cassettes, electronic clock, e tc, these a re to be reset before returning the vehicle to t he client. Check t he c ooling fan opera tion: start the vehicle engine and disconnect the water
temperature sensor. The cooling fa n must start. Reconnect the water t emperature sensor,
then by means of the CLIP tester, erase the memorized failure related to the water t em-
perature sensor.
