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 electric motor, washers.
Tighten the attachement screw (3) of the assembly.
Replace the clip from point (7).
Mount the wiring of the cooling fan assembly taking into the consideration the mount-

ing position marked before dismounting. This is to be fixed by means of a clip in point (7)
and will pass trough the clip (6).

Connect the cooling fan resistance connector (1).
Connect the cooling fan connector (5). Observe the mounting position identification of

the two connectors.

Connect the battery plug (-). In case the vehicle is equipped with progammable radio-

cassettes, electronic clock, etc, these are to be  reset before returning the vehicle to the client.

Check the cooling fan operation: start the vehicle engine and disconnect the water

temperature sensor. The cooling fan must start. Reconnect the water temperature sensor,
then by means of the CLIP tester, erase the memorized failure related to the water tem-
