WATER PUMP - V-6 AND V-8 ENGINES

REMOVAL

The water pump on all models can be removed without discharging the air conditioning system (if equipped)

The water pump on all gas powered engines is bolted directly to the engine timing chain case/cover.

On all 3.9L/5.2L/5.9L gas powered engines, a gasket is used as a seal between the water pump and timing chain case/cover.

If water pump is replaced because of bearing/shaft damage or leaking shaft seal, the mechanical cooling fan assembly should also be inspected. Inspect for fatigue cracks, loose blades or loose rivets that could have resulted from excessive vibration. Replace fan if any of these conditions are found. Also check condition of the thermal viscous fan drive. Refer to Viscous Fan Drive in this group.

  1. Disconnect negative battery cable from battery.
  2. Drain cooling system. Refer to Draining Cooling System in this group.

Do not waste reusable coolant. If solution is clean, drain coolant into a clean container for reuse.

  1. Remove windshield washer reservoir tank from radiator fan shroud. Refer to Windshield Wiper and Washer Systems.
  2. Disconnect the coolant reserve/overflow tank-to-radiator hose at the tank.
  3. Remove the four fan shroud mounting bolts at the radiator Do not attempt to remove shroud from vehicle at this time

    WARNING: CONSTANT TENSION HOSE CLAMPS ARE USED ON MOST COOLING SYSTEM HOSES. WHEN REMOVING OR INSTALLING, USE ONLY TOOLS DESIGNED FOR SERVICING THIS TYPE OF CLAMP, SUCH AS SPECIAL CLAMP TOOL (NUMBER 6094) SNAP-ON CLAMP TOOL (NUMBER HPC-20) MAY BE USED FOR LARGER CLAMPS. ALWAYS WEAR SAFETY GLASSES WHEN SERVICING CONSTANT TENSION CLAMPS.

    CAUTION: A number or letter is stamped into the tongue of constant tension clamps If replacement is necessary, use only an original equipment clamp with a matching number or letter.

  4. Remove upper radiator hose at radiator.
  5. The thermal viscous fan drive is attached (threaded) to the water pump hub shaft Remove the fan/fan drive assembly from water pump by turning the mounting nut counterclockwise (as viewed from front) Threads on the 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. Place a bar or screwdriver between the water pump pulley bolts to prevent the pulley from rotating.
  6. If water pump is being replaced, do not unbolt fan blade assembly from the thermal control fan drive.
  7. Remove fan blade/fan drive and fan shroud as an assembly from vehicle.
  8. 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 drive could drain into its bearing assembly and contaminate the bearing lubricant.
  9. Do not remove the water pump pulley bolts at this time
  10. Remove accessory drive belt as follows: The drive belt is equipped with a spring loaded automatic tensioner
  11. 3.9L V-6 or 5.2/5.9L V-8 LDC-Gas Engines: Relax the tension from the belt by rotating the tensioner clockwise (as viewed from front) When all belt tension has been relaxed, remove accessory drive belt.
  12. 5.9L HDC-Gas Engine: Relax the tension from the belt by rotating the tensioner counterclockwise (as viewed from front) When all belt tension has been relaxed, remove accessory drive belt.
  13. Remove the four water pump pulley-to-water pump hub bolts and remove pulley from vehicle.
  14. Remove the lower radiator hose and heater hose from water pump.
  15. Loosen heater hose coolant return tube mounting bolt Coolant Return Tube - 3.9L V-6 or 5.2/5.9L V-8 LDCand remove tube from water pump. Discard the old tube O-ring
  16. Remove the seven water pump mounting bolts -
  17. Loosen the clamp at the water pump end of bypass hose Slip the bypass hose from the water pump while removing pump from vehicle. Do not remove the clamp from the bypass hose.
  18. Discard old gasket

    CAUTION: Do not pry the water pump at timing chain case/cover. The machined surfaces may be damaged resulting in leaks.

INSTALLATION

  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 Coat the new o-ring with antifreeze before installation.
  6. Install coolant return tube and its mounting bolt to engine Be sure the slot in tube bracket is bottomed to mounting bolt. This will properly position return tube.
  7. Connect radiator lower hose to water pump.
  8. Connect heater hose and hose clamp to coolant return tube.
  9. Install water pump pulley. Tighten bolts to 27 N·m (20 ft. lbs.) torque. Place a bar or screwdriver between water pump pulley bolts to prevent pulley from rotating.
  10. Relax tension from automatic belt tensioner Install drive belt

    CAUTION: When installing the serpentine accessory drive belt, the belt must be routed correctly. If not, engine may overheat due to water pump rotating in wrong direction. Refer to for correct belt routing. The correct belt with correct length must be used

  11. Position fan shroud and fan blade/viscous fan drive assembly to vehicle as a complete unit.
  12. Install fan shroud.
  13. Install fan blade/viscous fan drive assembly to water pump shaft.
