Before removing the electric fan assembly, disconnect the negative cable from the battery. Remove the fastening brackets and take out the water deflector 1 (see fig. 172) and sealant. Disconnect the electrical wire under the instrument panel, going to the electric motor, and the wire fixed under the left front nut of the heater 5 to the air intake box. Unscrew the two fixing screws and remove the electric fan assembly.
Disconnect casing 3 (see fig. 170) and 6 of the electric fan and remove the electric motor 4 of the heater assembly with the impeller 5, having previously disconnected the mounting brackets.
The assembly of the electric fan and its installation is carried out in the reverse order. When assembling, it is necessary to pay attention to the correct installation of the sealant of the electric fan casings. To avoid imbalance, it is not allowed to remove the impeller from the motor shaft.
