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
