8 Disconnect the battery negative lead, and remove the radiator grille. On Ghia models, remove the front bumper.
9 Disconnect the fan wiring connector at the side of the condenser.
10 Remove the three securing bolts and withdraw the fan assembly. Turn the frame to position the fan wiring on the dehydrator side to avoid damaging the wiring. Take care also not to damage the condenser fins or tube.
11 To remove the fan blades from the motor, remove the retaining nut and circlip. The nut has a left-hand thread, ie, it is undone in a clockwise direction.
12 With the blades removed, the motor can be unscrewed from the frame.
13 Reassemble and refit in the reverse order of dismantling and removal.
Models from 1987
14 Disconnect the battery negative lead.
15 Remove the bonnet lock.
16 Unclip the guard from the fan frame.

24 Disconnect the thermostat from the evaporator casing and withdraw it. Also withdraw the thermostat probe from the casing.
25 Refitting is a reversal of removal.
