Radiator Fan

1. If coolant temperature is low (below 181°F on models less A/C; below 185°F on A/C-equipped models), proceed as follows:
a. Turn ignition switch on and check that cooling fan is not operating.
b. If fan is operating, check for faulty fan relay and/or temperature switch. Check too for separated electrical connectors or severed wire between relay and temperature switch.
c. Disconnect temperature switch wire, then check that fan rotates.
d. If fan does not rotate, check fan relay, fan motor, ignition relay and fuse. Check for short circuit between fan relay and temperature switch.
e. Connect temperature switch wire.
2. If coolant temperature is high (above 194°F on A/C-equipped models; above 199°F on models less A/C) proceed as follows:
a. Raise engine temperature above specified limit, then check that fan rotates.
b. If fan does not rotate, replace temperature switch.
