E220 fan in front of the water pump is loose. can this be tightened

fan clutches are Left hand thread as they tighten up when the engine is running. If they were right hand thread then when the fan is working they would come loose off the shaft
In short undoing then actually tightens them

Instructions

1. 4.0L Explorer Engines
   • 1Place a drain pan underneath the radiator. When the engine is cool, drain the cooling system from the radiator into the pan.
     
   • 2Remove the fan shroud, the cooling fan, the accessory drive belt and the water pump pulley with the bolts.
     
   • 3Disconnect the coolant bypass hose and the lower radiator hose.
     
   • 4Loosen and remove the bolts attaching the water pump and remove the pump from the engine.
     
   • 5Clean all the mounting surfaces to the water pump.
     
   • 6Install the new pump, tightening the bolts to 89 inch pounds (20 to 28 Nm).
     
   • 7Reattach and install all components in reverse order from removal. Tighten the water pump pulley bolts to 18 foot pounds (25 Nm).
     
   • 8Refill the cooling system. Start the car and check for leaks when the engine reaches normal operating temperature.
     
   5.0L Explorer Engines
   • 9Disconnect the negative battery cable and place a drain pan underneath the radiator. When the engine is cool, drain the cooling system from the radiator into the pan.
     
   • 10Remove the fan shroud, the cooling fan, the accessory drive belt and the water pump pulley with the bolts.
     
   • 11Take out the accessory drive belt. Disconnect and remove the heater hose and the bypass hose from the pump.
     
   • 12Remove the brackets to the engine control sensor wiring. Move the harness out of the way.
     
   • 13Loosen and remove the bolts to the water pump pulley and the water pump and remove the pulley.
     
   • 14Pull the water pump out and away from the front cover. Once the water pump is out of the way, disconnect the lower radiator hose. Then, take the water pump out of the engine.
     
   • 15Clean the front cover to the water pump and all the mounting surfaces. Put some adhesive gasket sealer on both sides of a brand new gasket and put it on the pump.
     
   • 16Reattach the lower radiator hose to the pump and reattach the pump, tightening the bolts to 15 to 21 foot pounds (20 to 28 Nm).
     
   • 17Reattach and reinstall all components in reverse order to their removal.
     Reattach the negative battery cable and refill the cooling system. Start the car and check for leaks when the engine reaches normal operating temperature.
     

Place the drain pan under the radiator drain plug, open the plug and allow it to drain. Close the plug. Loosen the four nuts on the water pump pulley but do not remove them yet. Loosen the adjusting bolts in the alternator and the power steering pump with a wrench, push them away from the belts and remove the belts.

2Remove the bolts securing the fan shroud to the radiator support using a 10 mm socket. Remove the four nuts on the water pump pulley, then remove the fan and shroud as an assembly. Remove the bolts in the crankshaft pulley using a socket. Loosen and remove the crankshaft bolt using a socket.

• 3
  

Remove the top radiator hose. Extract all the 10 mm bolts securing the top and bottom timing covers and remove the covers.

4Install the crankshaft bolt temporarily. Use a socket on the bolt and turn the crankshaft clockwise until the mark on the crankshaft sprocket aligns with the timing mark on the block at the 12 o'clock position. Look at the camshaft sprockets and make sure the left sprocket has the "I" facing straight up and the right sprocket has the "E" facing up. At the same time, notice that there is a line on each sprocket adjacent to each mark--make sure they line up with the notch on the cylinder head at 12 o'clock. This allows for perfect alignment. If they do not come close to aligning, rotate the crankshaft one more time and they will align.

5Loosen the tensioner bolt and push the tensioner away from the belt. Loosely tighten the bolt to maintain position. Remove the belt.

6Install the new belt starting on the right side away from the tensioner. Keep all the tension on the right side. Loosen the tensioner bolt and allow it to apply tension on the belt. Do not tighten the bolt yet. Rotate the engine two turns clockwise and re-align the timing marks. Tighten the tensioner bolt to 35 foot-pounds.

7Install the timing belt covers. Remove the crankshaft bolt and install the crankshaft pulley. Reinstall the bolt and tighten. Install the radiator shroud and fan as an assembly. Place the fan on the water pump pulley, install the four nuts loosely, install the bolts in the fan shroud and tighten.

8Install the belts around the crank pulley, water pump pulley and alternator and pull the alternator up to tension the belt and tighten the bolts using a socket. Tighten the water pump pulley nuts using a wrench.

9Install the belt on the power steering pump, pull the pump out to tension the belt and tighten the bolts. Install the upper radiator hose. Fill the radiator with antifreeze

well if your leaking from your water pump it shouldnt be the screws loose. there is a weepm hole that when that leaks it means your ater pump is bad. but if the screws are loose just get a socket set an ratched an extention an tighten them up. the water pump is the pulley that has the fan on it.

Fig. 1: Front cover and water pump bolt size and location-3.0L engine

1. Disconnect the negative battery cable.
2. Drain and recycle the engine coolant.
3. Loosen the four water pump pulley retaining bolts while the accessory drive belts are still tight.
4. Rotate the automatic tensioner down and to the left.
5. Remove the accessory drive belt.
6. Remove the two nuts and bolt retaining the drive belt automatic tensioner to the engine, then remove the tensioner.
7. Disconnect and remove the lower radiator and heater hose from the water pump.
8. Remove the eleven water pump-to-engine retaining bolts, then lift the water pump and pulley up and out of the vehicle.
9. Remove the water pump pulley retaining bolts, then remove the pulley from the water pump.
   

To install:
Be careful not to gouge the aluminum surfaces when scraping the old gasket material from the mating surfaces of the water pump and front cover.

1. Clean the gasket surfaces on the water pump and front cover. Lightly oil all bolt and stud threads except those requiring special sealant.
2. Position a new water pump housing gasket on the water pump sealing surface using gasket sealant to hold the gasket in place.
3. With the water pump pulley and retaining bolts loosely installed on the water pump, align the water pump-to-engine front cover, then install the retaining bolts.
4. Tighten the bolts to the following specifications:
   1. Bolt numbers 1-10: 15-22 ft. lbs. (20-30 Nm).
   2. Bolt numbers 11-15: 71-106 inch lbs (8-12 Nm).
      
5. Hand-tighten the water pump pulley retaining bolts.
6. Install the automatic belt tensioner assembly. Tighten the two retaining nuts and bolt to 35 ft. lbs. (47 Nm).
7. Install the alternator and power steering belts. Final tighten the water pump pulley retaining bolts to 15-22 ft. lbs. (22-30 Nm).
8. Position the hose clamps between the alignment marks on both ends of the hose, then slide the hose on the connection. Tighten the hose clamps to 20-30 inch lbs. (2.2-3.4 Nm).
9. Fill and bleed the cooling system.
10. Connect the negative battery cable.
11. Start the engine and check for leaks.

Hope this help to solve it (remember comment and rated this).

sounds like you have a fan belt loose or misaligned

the water pump is loose thats what the fan is attached to .replace it and you will be fine thanks for your question.

You can get the special tools to remove it or some people take a air hammer with a pointed bit and give the edge of the nut a quick hit in the direction the fan spins to break loose the nut.And to tighten it thread it back on half way then start the engine and when it spins it will tighten it up.
