COOLING SYSTEM COMPONENTS
Fan Control Circuit Operation / Testing
Power is supplied to the fan via the Orange/Black wire
when the relay is ON. The ground path for the fan motor
is through the Brown harness wire. Refer to “RELAYS”
later in this chapter for more information on fan functions.
CAUTION
Keep hands away from fan blades during operation.
Serious personal injury could result.
NOTE: The fan may not function or operation may
be delayed if coolant level is low or if air is trapped in
the cooling system. Be sure cooling system is full
and purged of air. Refer to Maintenance Chapter 2
for cooling system information.
Fan Control Circuit Bypass Test
1. Disconnect harness from coolant temperature
sensor on engine.
2. With the ATV in “Park” and with the parking brake on,
turn the ignition key (and engine stop switch) “ON”.
The fan should start running.
3. If the fan does not run or runs slowly, check the fan
motor wiring, ground, motor condition and
mechanical relay for proper operation (refer to “FAN
MOTOR CURRENT DRAW” in this section). Repair
or replace as necessary. If the fan runs with the
sensor harness disconnected, but will not turn on
when the engine is hot, check the coolant
temperature sensor and connector terminals.
Coolant Temperature Sensor
The coolant temperature sensor can be tested using an
ohmmeter or voltmeter.
1. With the engine and temperature sensor at room
temperature (68°F = 20°C), disconnect the harness
connector.
2. With the meter in the ohms mode, place the meter
leads onto the sensor contacts.
3. Use the table Temperature / Resistance table to
determine if the sensor needs to be replaced.
TEMPERATURE °F (°C)
RESISTANCE
68 °F (20 °C)
2.5 kΩ ± 6%
212 °F (100 °C)
0.186 Ω ± 2%
NOTE: If the coolant temperature sensor or
circuit malfunctions the radiator fan will default
to 'ON'.
The fan may not function or operation may be
delayed if coolant level is low or if air is trapped
in the cooling system. Be sure cooling system is
full and purged of air. Refer to Maintenance
Chapter 2 for cooling system information.
