Repair or replace components as necessary. If no problems exist, go to
next step.
2) Ground fan motor 3-pin connector terminal No. 3 (Black
wire). Using a fused jumper wire, connect battery voltage to 3-pin
connector terminal No. 2 (Blue wire). See WIRING DIAGRAMS. Fan motor
should operate with no abnormal noises or interferences. Repair or
replace components as necessary.
Engine Coolant Temperature (ECT) Sensor
Remove ECT sensor from vehicle. Suspend sensor in water so
that sensor does not touch container. Slowly heat water. Using an
ohmmeter, check sensor continuity as temperature increases. Replace
ECT sensor if resistance is not as specified. See
ENGINE COOLANT TEMPERATURE SENSOR RESISTANCE table.

Electric Cooling Fan Relay (Diamante, Eclipse, Galant &
Mirage)
1) Remove radiator fan motor relay from relay box located at
right side of engine compartment. Check for continuity between relay
terminals No. 1 and 3. If continuity exists, go to next step. If
continuity does not exist, replace cooling fan relay. See Fig. 8.
2) Using a fused jumper wire, connect battery voltage to
cooling fan relay terminal No. 1. Using another jumper wire, connect
cooling fan relay terminal No. 3 to battery ground. With cooling fan
relay energized, there should be continuity between cooling fan relay
terminals No. 4 and 5. With cooling fan relay not energized, there
should be no continuity between terminals No. 4 and 5. If continuity
does not exist as specified, replace cooling fan relay. See Fig. 8.
Electric Cooling Fan Relay (Montero, Montero Sport & 3000GT)
1)Remove relay from relay box in engine compartment relay
box. Check for continuity between relay terminals No. 2 and 4. If
continuity exists, go to next step. If continuity does not exist,
replace cooling fan relay. See Fig. 9.
2) Using a fused jumper wire, connect battery voltage to
Page 280 of 1501
cooling fan relay terminal No. 2. Using another jumper wire, connect
cooling fan relay terminal No. 4 to battery ground. With cooling fan
relay energized, there should be continuity between cooling fan relay
terminals No. 1 and 3. With cooling fan relay not energized, there
should be no continuity between terminals No. 1 and 3. If continuity
does not exist as specified, replace cooling fan relay. See Fig. 9.

SYSTEM TESTING
NOTE: For appropriate wiring diagram, see WIRING DIAGRAMS.
NOTE: Radiator fan on Montero and Montero Sport is mounted to a
hydraulic fan clutch which is mounted to the water pump.
Replace fan clutch if leaks are detected at case joints and
seals, fan can be rotated with very light resistance or the
bimetallic strip is damaged.
NOTE: Operation of radiator and condenser fans is controlled by
vehicle Powertrain Control Module (PCM). Based on vehicle
Page 282 of 1501
speed, coolant temperature and A/C operation request, PCM
will command low, medium or high speed fan operation.
Diamante
1) If only the radiator fan does not operate, check fusible
link No. 6 located in engine compartment relay box. If only the
condenser fan does not operate, check dedicated fuse No. 16 (20-amp)
located in engine compartment relay box. See WIRING DIAGRAMS. Repair
as necessary.
2) If radiator fan and condenser fan operate in all speeds
except low, check appropriate low speed relay. See COMPONENT TESTS.
See WIRING DIAGRAMS . If low speed relay is okay, check PCM. See
appropriate G - TESTS W/CODES article in ENGINE PERFORMANCE.
* G - TESTS W/CODES - 1997
* G - TESTS W/CODES - 1998
3) If radiator fan and condenser fan operate in all speeds
except high, check appropriate high speed relay. See COMPONENT TESTS.
See WIRING DIAGRAMS . If high speed relay is okay, check PCM. See
appropriate G - TESTS W/CODES article in ENGINE PERFORMANCE.
* G - TESTS W/CODES - 1997
* G - TESTS W/CODES - 1998
4) To confirm radiator fan or condenser fan operation, see
FAN OPERATING MODE (DIAMANTE) table. If fan operation is not as
specified, check wiring harness for opens or shorts. Repair as
necessary.
