Note: When installing the circuit breaker, use a new O-ring.
Removing
1. The fan switch is installed in the lower right corner of the radiator (see illustration).
2. If there is any doubt that the switch is working, check the wiring going to the fan motor by temporarily connecting the switch wiring connector pins and turning the ignition on. If the cooling fan still runs, the switch is defective and should be replaced. To remove the switch, proceed as follows.
3. Disconnect the negative cable from the battery, then disconnect the electrical wiring connector at the switch (if not already done).
4. Drain the cooling system as described in Chapter 2.
5. Unscrew the switch from the radiator and remove the O-ring.
Installation
6. Installation is carried out in the reverse order. Use a new O-ring. When finished, fill the cooling system as described in Chapter 4.
7. Finally, start the engine, let it warm up to normal operating temperature and check that the fan is working properly.
