How do i remove water pump from a 2002 discovery, which way does the large nut on the shaft tighten? to the right or to the left?

The question is: How remove clutch in order to remove fan mounted on its engine-side face.

• Generally, the clutch drive half shaft must be uncoupled from coolant pump (impeller drive) half shaft using special wrench kit available as loaner from AutoZone (free with $79 approx deposit).
• Best done after shroud & radiator remove after coolant drained.

1. Uncouple coolant pump and fan clutch drive shaft(s) as follows:
   
   1. span across combo-pulley-sheaves-unit mounting bolt heads with large tool kit wrench, and
   2. span inline clutch coupling nut with small tool kit wrench. Then,
   3. turn small wrench (and coupling nut) CW while resisting with large wrench (CCW) to turn coupling nut until disengaged from coolant pump drive shaft.
2. Remove fan/clutch assembly.
3. Note direction of mounted fan hub and fan blades orientation to ensure proper re-assembly.
4. On rear of clutch assy, remove 4 bolts to disengage and remove fan.
5. Assemble new fan to clutch (or, preferably, new clutch and new fan) using new bolts and washers provided with fan.
6. Couple fan-clutch assy to coolant pump drive shaft as per opposite of uncoupling step 1, above. (Turn inline nut CCW to tighten...30 ft-lb.
7. Check that fan can be hand turned...CW.)
8. Rest shroud over and onto fan.
9. Replace radiator; remount shroud; reclamp hoses, and refill and air purge cooling system.

You don't change the cv joint. You purchase a half shaft left or right side and you replace the whole axle shaft they are around $150.00. Take off the tire, remove axle shaft nut, remove spindle from lower ball joint and pull the axle out of spindle then you take a large pry bar and carfully pop the axle shaft out of the transmission. Very easy job only takes about 1 hour to for complete job.

Hello ggagne.
Here is the procedure.

1. Raise and suitably support the vehicle.
2. Remove the left tire and wheel assembly.
3. Remove the pinch bolt from the lower intermediate steering shaft
4. Loosen all insulator clamp attaching bolts.
5. Place a jack stand under the center of the rear frame cross member.
6. Remove the rear frame-to-body bolts.
7. Lower the rear of the frame just enough to gain access to the stabilizer shaft.
8. Remove the insulator clamp bolts and the clamps from the frame.
9. Remove the insulators from the stabilizer bar.
10. Remove the stabilizer bar links from the control arms.
11. Pull the stabilizer shaft rearward.

Installation

1. Insert the stabilizer shaft to the left side of the vehicle. Important: DO NOT tighten the stabilizer link nut at this time. The weight of the vehicle must be supported by the control arms such that you can obtain the vehicle design trim heights before tightening the link nut.
2. Loosely install the stabilizer shaft link at the control arm.
3. Install the insulators on to the stabilizer bar.
4. Connect the insulator clamps to the frame.
• Tighten the stabilizer shaft bracket bolts to 48 Nm (35 ft. lbs.) .
5. Raise the frame into position while you guide the steering shaft onto the gear.
6. Install the new frame-to-body attaching bolts.
7. Remove the jack stand.
8. Install the pinch bolt and tighten.
9. Install the left tire and wheel assembly.
10. Lower the vehicle.
11. Support the weight of the vehicle by the control arms.
12. Tighten the stabilizer link nut.
• Tighten the stabilizer shaft link nut to 23 Nm (17 ft. lbs.)
  

There you are, I hope your job goes well.
Thank you for using FixYa.

Use something to place between two of the bolts on the belt pulley to hold it from turning. Use a large wrench (cresent will work) and turn the large nut head of the fan clutch in the same direction that the pulley turns. It might be tight so you may have to pop it.

The water pump and related area may be leaking antifreeze. Check near the belt pulley for the water pump. There may be other issues that require the gasket further in the engine changed which is related to engine oil. My family had a 1998 Ford Taurus that had this problem and it cost a few hundred to have it fixed.

One may also look for a leak at the radiator (or hoses )which is further forward.

Water pump bolt torque sequence (3.0L (2V) engine)

Not sure if it is the same, but I have a 1996 328i and the fan is attached to the front of the water pump via a large nut. That nut is a 32 mm (1 and 1/4 inch fits it as well), and is BACKWARDS threaded (i.e right to loosen and left to tighten). You may need to use a pair of vise grips and lock onto the belt to keep the entire front of the motor from turning. I have also heard giving it a few good whacks from a rubber mallet tends to get them to break free. If you do have to use the Visa grips on the belt be careful to not break your water pump pulley. Although it looks to be made of metal it is actually made of plastic and will break if it gets caught up in the tension of turning that fan nut. When the motor is running it is turning in the tightening direction, so I put some anti-sieze on the threads before re-installing. Hope that helps.

what's up led, the large viscous nut is loosened in the clockwise direction. after you remove the 4 nuts on the water pump, you should see one hole on each side of the water pump body. if you take 2 bolts out of the thermostat housing, you can use those to thread in the pump body holes.slowly tighten each bolt equally and the pump should come out. to install a new pump, lubricate the o-ring on the new pump and just push in by hand.
