Cooling Fan (Crankshaft driven)
REMOVAL AND INSTALLATION
=NBLC0038
I
Do not release the drive belt tension by removing the fan/water
pump pulley.
I
Fan coupling cannot be disassembled and should be replaced
as a unit. If front mark F is present, install fan so that side
marked F faces the front.
I
Install the drive belt only after the fan and fan coupling to water
pump flange bolts/nuts have been properly torqued.
I
Proper alignment of these components is essential. Improper
alignment will cause them to wobble and may eventually cause
the fan to separate from the water pump causing extensive
damage.

INSPECTION
NBLC0039
Check fan coupling for rough operation, wobbling, oil leakage or
bent bimetal.
SLC151B

When the engine is running, keep hands and clothing
away from moving parts such as drive belts and fan.
