Fan Blade: Service and Repair
REMOVAL
NOTE: Fan belt removal is not necessary to remove cooling system fan.
1. Disconnect the negative battery cable at battery.
2. Remove the plastic air cleaner intake tube.
3. Remove two-piece fan shroud. Remove lower half first.
4. The thermal viscous fan drive/fan blade assembly is attached (threaded) to the water pump hub shaft. Remove the fan blade/fan drive assembly
from water pump by turning the mounting nut counterclockwise (as viewed from front). Threads on the viscous fan drive are RIGHT HAND. A
Snap-On 36 MM Fan Wrench (number SP346 from Snap-On Cummins Diesel Tool Set number 2017DSP) can be used with Special Tool 6958
Spanner Wrench and Adapter Pins 8346 to prevent the pulley from rotating.
Do not unbolt fan blade assembly from the viscous fan drive at this time.
5. After removing fan blade/fan drive assembly do not place the thermal viscous fan drive in the horizontal position. If stored horizontally, the
silicone fluid in the viscous fan drive could drain into its bearing assembly and contaminate the bearing lubricant.
