Replacing water pump


This is for the 3.9 v6 you did not specify motor size.
Hope this helps, it it does please leave feedback Thank You and Good Luck


The water pump can be removed and installed without discharging the air conditioning system (if equipped).
  1. Disconnect battery negative cable.
  2. Drain cooling system.
  3. Do not waste reusable coolant. If solution is clean, drain coolant into a clean container for reuse.
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 matching number or letter.


  1. Remove upper radiator hose clamp and hose at radiator.
Fan Blade And Viscous Fan Drive-3.9L/5.2L/5.9L Engines 81898572


  1. 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) can be used. Place a bar or screwdriver between water pump pulley bolts to prevent pulley from rotating. Do not attempt to remove fan/viscous fan drive assembly from vehicle at this time.
  2. If water pump is being replaced, do not unbolt fan blade assembly from thermal viscous fan drive.
  3. Remove fan shroud attaching hardware (two bolts at bottom-two clips at top).
  4. Remove fan shroud and fan blade/viscous fan drive assembly from vehicle as a complete unit.
  5. 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.
  6. Do not remove water pump pulley bolts at this time.
Automatic Belt Tensioner Assembly-3.9L/5.2L/5.9L Engines 81898573


  1. Remove accessory drive belt as follows: The drive belt is equipped with a spring loaded automatic tensioner. Relax tension from belt by rotating tensioner clockwise (as viewed from front). When all belt tension has been relaxed, remove accessory drive belt.
  2. Remove four water pump pulley-to-water pump hub bolts and remove pulley from vehicle.
  3. Remove lower radiator hose clamp and remove lower hose at water pump.
  4. Remove heater hose clamp and heater hose from heater hose coolant return tube.
Coolant Return Tube-3.9L/5.2L/5.9L Engines-Typical 81898574


  1. Loosen heater hose coolant return tube mounting bolt and remove tube from water pump. Discard the old tube O-ring.
Water Pump Bolts-3.9L/5.2L/5.9L Engines 81898575


  1. Remove seven water pump mounting bolts.
  2. Loosen clamp at water pump end of bypass hose. Slip bypass hose from water pump while removing pump from vehicle. Discard old gasket.

How do i change a water pump on 1996 grand cherokee limited V8


I'll assume you have a 4.0l

The 4.0L engine is equipped with a reverse rotation (counterclockwise) water pump. The word REVERSE is stamped or imprinted on the cover of the viscous fan drive and on the inner side of t he fan. The letter R is stamped onto the water pump impeller. When replacing water pump, ensure proper pump is installed. Installation of the wrong water pump will cause engine overheating.

NOTE:On models with 4.0 L engine, front grill must be removed to access radiator draincock. Draining cooling system can be accomplished by removing drain plug from side of block as well as by loosening radiator draincock. Drain plug is located on lower left side of engine block.

Disconnect negative battery cable. Drain cooling system. Disconnect electric cooling fan connector. Remove electric cooling fan and electric fan shroud assembly (if equipped).
Loosen, but do not remove, 4 water pump pulley-to-water pump hub bolts and 4 viscous fan-to-idler pulley nuts. Remove accessory drive belt. Remove 4 viscous fan to idler pulley nuts, and remove fan and shroud together.
Remove 4 water pump pulley bolts and remove pulley. Remove power steering pump and bracket. Disconnect heater hoses and lower radiator hose at water pump. Remove 4 water pump retaining bolts. Remove water pump.

WATER PUMP
The water pump is bolted directly to the engine timing chain case/cover.

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.

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

REMOVAL
Disconnect negative battery cable from battery.
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.

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.
