3 The motor can be separated from the fan shroud by unscrewing the three securing nuts and bolts.

4 Where two cooling fans are fitted, both fans are secured to the fan shroud in the same manner.

5 Refitting is a reversal of removal, but when refitting the fan blades, ensure that the direction of rotation arrow faces away from the motor, towards the radiator.

DOHC models
6 Disconnect the battery negative lead.

7 To provide additional clearance when removing the cooling fan shroud assembly (which is removed from below the vehicle), apply the handbrake, then jack up the front of the vehicle and support it securely on axle stands (see “Jacking and Vehicle Support”).

8 Disconnect the wiring plug(s) from the motor(s), and where applicable, unclip the wiring from the fan shroud.

9 Unclip the expansion tank hose from the fan shroud.

10 Unscrew the two nuts securing the fan shroud to the top of the radiator, then tilt the top of the shroud away from the radiator, and lift the shroud to release the lower securing clips. Withdraw the assembly from below the vehicle.

11 To remove the fan blades, prise the securing clip from the end of the motor shaft.

12 The motor can be separated from the fan shroud by unscrewing the three securing nuts and bolts.

13 Where two cooling fans are fitted, both are secured to the shroud in the same manner.

14 Refitting is a reversal of removal, but when fitting the fan blades, ensure that the drive dog on the motor shaft engages with the slot in the rear of the fan blades.

Cooling fan switch - removal and refitting

On CVH models, the cooling fan switch is located on the right-hand side of the thermostat housing (see illustration). On DOHC models, the switch is located in the end of the thermostat housing.

Removal and refitting of the switch is as described for the temperature gauge sender.
