You will need to keep the pulley from turning, somehow. Or use the correct tool. Sometimes you can give the wrench a good whack and it will knock it loose.

Remove and replace alternator


Hello,

Just follow these steps to remove and replace the alternator. You will need this tools, Serpentine belt tool, Battery wrench, Lug wrench, Floor jack, Jack stand, Socket set,

  1. Open the hood, locate the serpentine belt tensioner and move the tensioner off the
    serpentine belt with the serpentine belt tool. Slip the belt off the tensioner
    pulley with your other hand and then slowly move the tensioner back to its normal
    position. You can pinpoint the location of the belt tensioner by following the belt
    routing diagram, printed on the fan shroud.
  2. Disconnect the negative battery cable from the battery with the battery wrench.
    Push the cable end away from the battery so it doesn't make contact during the
    repair.
  3. Turn the lug nuts on the right-front wheel counterclockwise until they're loose
    enough for hand removal, but leave them on for now.
  4. Lift the right-front end with the floor jack and support it on a jack stand placed
    underneath the right-front frame. Remove the lug nuts and right-front wheel by hand
    and set them aside.
  5. Slip the serpentine belt off the alternator pulley by hand. You can access the
    alternator through the wheel well. Unplug the wiring harness from the alternator
    by hand and remove the ground strap with your socket set.
  6. Remove the alternator mounting bolts with your socket set. Lift the alternator out
    of the engine well, through the wheel well. Insert the new alternator in reverse of
    how you removed the old one.
  7. Thread the alternator mounting bolt through the new alternator and into the
    alternator bracket by hand. Tighten the bolts with your socket set.
  8. Attach the alternator ground strap with your socket set. Plug the alternator
    wiring harness in by hand.
  9. Slip the serpentine belt over the new alternator pulley. Reinstall the wheel and
    lug nuts by hand. Lower the Taurus of the jack stand with the floor jack.
  10. Move the belt tensioner aside again and place the belt on the tensioner pulley with
    your free hand. Hold the belt on the pulley and slowly move the tensioner back to
    its normal position. Reconnect the negative battery cable to the battery.
Hope this helps you.
Take care and good luck

JUST A DIAGRAM OF THE SERPENTINE BELT ROUTE


The diagram can be found here.
Remove the upper fan shroud and aircleaner assemblies for easy access.
To release tension on the belt turn the tensioner pulley nut clockwise and slip the belt off the alternator pulley. To refit the belt route as shown over every pulley except the alternator, once again release the tensioner and fit the belt to the alternator. See that the belt is properly seated over every pulley before restarting the engine.

How to remove fan


Congrats, I have one 1993 GC Limited and its a nice SUV...

5.2L Engines

  1. Disconnect the negative battery cable.
  2. The viscous fan drive and blade assembly is threaded into the water pump hub shaft. Remove the fan drive and blade assembly from the water pump by turning the mounting nut counterclockwise as viewed from the front while securing the water pump pulley. Do not remove or unbolt the fan drive and blade at this time.

Fig. : Fan blade and viscous drive (click for zoom)


The threads on the viscous fan drive are right hand threaded.
  1. Remove the 2 fan shroud-to-upper crossmember nuts.
  2. Remove the fan drive, blade and shroud as an assembly.
WARNING Do not place the viscous fan drive in a horizontal position. If stored horizontally, silicone fluid in the viscous fan drive could drain into its bearing assembly and the assembly would have to be replaced.
CAUTION Do not remove the water pump pulley-to-water pump bolts. The pulley is under spring tension.
  1. Remove the 4 bolts securing the fan blade assembly to the viscous fan drive.
To install:
  1. Install the fan blade on the viscous drive. Install the bolts and tighten them to 17 ft. lbs. (23 Nm).
  2. Position the fan shroud, viscous fan and blade into the engine compartment as an assembly.
  3. Position the fan shroud to the radiator. Insert the lower slots of the shroud into the crossmember. Install the upper attaching nuts.
Ensure the upper and lower portions of the fan shroud are firmly connected. All air must flow through the radiator.
  1. Install the fan drive and blade assembly to the water pump shaft and tighten the nut.
Ensure there is at least 1 inch (25mm) between the tips of the fan blades and shroud.
  1. Connect the negative battery cable.

Hope helps with this (remember comment and rated this).

Car overheated and antifreze was boiling and spewing over until engine cooled. 2004 jeep liberty 2wd. Thanks!


Need to know what caused the overheating, possible broken serpentine belt, thermostat, water pump, radiator, fan clutch, cooling fan motor. After motor has cooled down fill radiator with water till full, look make sure serpentine belt not broke, start engine run about 5 minutes, turn off, let sit 3 minutes, start engine look at temperture gauge is it over half way of gauge, Do you have a fan blade driven by water pump or electric fans?

How do you replace the Serpentine Drive Belt


look at the pulleys, and locate the tensioner. It's usually in the center of all of the pulleys, and has the belt wrap around it, but isn't an obvious accessory like the alternator, PS pump, water pump, or crankshaft. The tensioner will have a square recess in it, allowing you to put a 3/8" square drive ratchet in it. When you turn it, you will notice that teh belt loosens. When it does, slip it off of the tensioner, but hold it in place for reference. Put the new belt on, routing it exactly like the old one, take out the old one, and load the tensioner exactly like you did when you loosened it. Ensure that the belt ribs are seated in the centers of all pulleys, and you are done.

Adjust tension on fan belt


Your '90 Benz has a belt tensioner that is automatic. You just insert the correct tool to ease the tensioner pulley, (The tool is inserted into the bracket for the tensioner pulley), to the left as you're facing the car. Then slip your serpentine belt off. Reinstallation is a reversal of this process. (I believe it's to the left, don't quote me on that)

The radiator support in front, should have a diagram of how the serpentine belt goes on the pulleys.

If your serpentine belt slips, then the belt tensioner pulley assembly is bad, needs to be replaced, or the serpentine belt itself is worn out.

Need diagram for 2000 dodge dakota serpentine belt


On the 1999 Dakota with the 3.9liter, the fan shroud absolutely DOES NOT have to be removed. Very simple job. Simply use a breaker bar with a 15mm socket on the belt tesioner pulley nut. Using the breaker bar push (as though tightening) the pulley nut...the reaction will be that the tensioner removes tension from the pulley and the entire belt can be removed by easily slipping it toward the front of the vehicle...comes right off. The new belt can go back on in exactly the same manner. By the way the belt routing diagram IS CONVIENENTLY LOCATED between the hood latch and the radiator mounting for simple and quick refernce...one person job, I did removal and installation four times in less than 10 minutes. (why four times? The auto parts store was selling replacement belts that were too long and did not allow the belt tensioner to provide suffiecient tension...I had to try four different manufacturers before the tensioner was adequately tight with room to grow as the belt naturally stretches from use.). I found no stringing around the fan is required because of the way the belt is routed (it doglegs around the main engine pulley which is centered below the fanhousing and then the belt runs from there to the left side of the fan housing...avoiding the fan/fanhousing all-together (sure you can try to go past the fan/fan housing if you so desire...but you dont have to...and besides the space between the pulleys and the fan is ample to allow the belt to pass between with minimal interference or a simple rotation of the fan as you attempt this method. One hint that made my installs easy as pie...the last pulley you put it over should not be a bezeled and ridged pulley or you will needlessly make life difficult for yourself...the last pulley should be the water pump pulley which is a smooth bore and non-ridged pulley (makes you wonder how the belt even stays on it!)...making it easy as pie to slip it right over...as your last act of defiance to that mean old serpentine belt!

Harmonic balancer for 1999 dodge ram 1500


well if i remember correctly that fan clutch is reverse threads so in other words to loosen it you'll have to turn your wrench clockwise. they do this cuz the rotation of the fan will tighten itself onto the water pump. anyway what i do is leave the serpentine belt on the the pulleys and that will kinda hold them steady whilst you put the "special" wrench on the clutch and pop it loose you'll prolly need a cheater bar to make things easier but not too much or you'll overcome the traction of the belt and it will just slip.
