Frontier 2WD V6-3.3L (VG33E) (2003)
Radiator Cooling Fan: Service and Repair
COOLING FAN (CRANKSHAFT DRIVEN)
Removal and Installation
^
Do not release the drive belt tension by removing the fan/water pump pulley.
^
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.
^
Install the drive belt only after the fan and fan coupling to water pump flange bolts/nuts have been properly torqued.
^
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
WARNING: When the engine is running, keep hands and clothing away from moving parts such as drive belts and fan.
^
Check fan coupling for rough operation, wobbling, oil leakage or
bent bimetal fins.
^
After assembly, verify the fan does not wobble or flap while the engine is running.
