2. The thermal viscous fan drive/fan blade assembly is attached (threaded) to water pump hub shaft. Remove fan blade/viscous fan drive assembly
from water pump by turning mounting nut counterclockwise as viewed from front. Threads on viscous fan drive are RIGHT HAND. Using spanner
wrench 6958 with adapter pins 8346 (4.7L engine only) and a suitable fan wrench loosen the fan drive.
3. Do not attempt to remove fan/viscous fan drive assembly from vehicle at this time.
4. Do not unbolt fan blade assembly from viscous fan drive at this time.
