  4. The thermal viscous fan drive is attached (threaded) to the water pump hub shaft Remove fan/viscous fan drive assembly from water pump by turning mounting nut counterclockwise as viewed from front. Threads on viscous fan drive are RIGHT HAND. A Snap-On 36 MM Fan Wrench (number SP346 from Snap-On Cummins Diesel Tool Set number 2017DSP) and Special Tool 6958 Spanner Wrench with Adapter Pins 8346 can be used. Place Special Tool 6958 Spanner Wrench onto the water pump pulley with Adapter Pins 8346 inserted into the holes on the pulley to prevent pulley from rotating. Do not attempt to remove fan/viscous fan drive assembly from vehicle at this time.
  5. If water pump is being replaced, do not unbolt fan blade assembly from thermal viscous fan drive.
  6. Remove fan shroud attaching hardware (two bolts at bottom-two clips at top)
  7. Remove fan shroud and fan blade/viscous fan drive assembly from vehicle as a complete unit.
  8. After removing fan blade/viscous fan drive assembly, do not place thermal viscous fan drive in horizontal position. If stored horizontally, silicone fluid in viscous fan drive could drain into its bearing assembly and contaminate lubricant.
  9. Remove accessory drive belt as follows: The drive belt is equipped with a spring loaded automatic tensioner
  10. Relax tension from belt by rotating tensioner clockwise (as viewed from front)
  11. When all belt tension has been relaxed, remove accessory drive belt.
  12. Remove lower radiator hose clamp and remove lower hose at water pump.
  13. Remove heater hose clamp and heater hose from heater hose coolant return tube.

  1. Clean gasket mating surfaces.
  2. Using a new gasket, install water pump to engine as follows: Guide water pump nipple into bypass hose as pump is being installed. Install water pump bolts. Tighten water pump mounting bolts to 40 N·m (30 ft. lbs.) torque.
  3. Position bypass hose clamp to bypass hose.
  4. Spin water pump to be sure that pump impeller does not rub against timing chain case/cover.
  5. Install a new O-ring to the heater hose coolant return tube
  6. Coat the new O-ring with antifreeze before installation.
