Cooling fan

Check

1 If the engine is overheating and the cooling fan isn't coming on, first check the cooling fan circuit fuse (see Chapter 9). If the fuse is good, check the fan switch as described below.

2 If the fan does not come on (and the fan switch is good), the fault lies in either the cooling fan motor or the relevant wiring. Test all the wiring and connections as described in Chapter 9, following the relevant Wiring Diagram. Disconnect the fan wiling connector and check that there is battery voltage at the black/blue or blue/black (according to model) wire terminal on the loom side of the connector with the ignition ON. If there is no voltage, check the wiring.

3 To test the cooling fan motor, on XL600V and XRV750 models remove the right-hand fairing side panel, and on XL650V models remove the fairing (see Chapter 8). Disconnect the fan wiring connector and the fan switch wiring connector (see illustrations). Using a 12 volt battery and two jumper wires with suitable connectors, connect the battery positive (+) lead to the black/blue or blue/black (according to model) wire terminal on the fan side of the wiring connector, and the battery negative (-) lead to the fan switch wiring connector. Once connected the fan should operate. II it does not. and the wiring Is all good, then the fan motor is faulty. Individual components are available for the fan assembly. Replacement

A Warning: The engine must be completely cool before carrying out this procedure.

4 Remove the right-hand radiator (see Section 6).

5 Disconnect the wiring connector from the fan switch (see illustration). Free the wiring from any clips.

6 Undo the bolts securing the fan assembly to the radiator, noting that one of them also secures the earth (ground) wire (see Illustration)

7 Unscrew the fan blade nut and remove the blade, noting how it locates. Undo the nuts on the front of the fan motor securing it to the shroud and separate them.

8 Installation is the reverse of removal. Apply a suitable non-permanent thread locking compound the fan blade nut and tighten it to the torque setting specified at the beginning of the Chapter. Also tighten the fan motor nuts to the specified torque. Do not forget to attach the earth (ground) cable to the radiator when fitting the fan assembly bolts.

9 Install the radiator (see Section 6).
