2006 F250s did not come with a 7.3l diesel. 2003 is the last year of the 7.3l. Either you have a 6.0l, made a typo in posting the year of your truck, or somebody swapped a 7.3 into that chassis.

Either way, the process is the same.

Totally release the belt tensioner and make sure the belt is on all the pullys correctly.pull as much slack as you can and slide the belt over the last smallest pully left.it is best to have help with this because its hard to see if the belt on the bottom end is correct and impossible to reach from the top

Does your truck have a belt tensioner on it? If so, use a 1/2" extention, with breaker bar, or ratchet, and relieve the stress from the belt. While holding the tensioner slide the belt back onto the alternator, and then let go. Make sure the belt is still driving all of your accesories. Hope this helps

How do I remove an altinator from a 2004 ford escape.


Hello there,
To replace the alternator in your car:
Open the Escape's hood, and examine the belt-routing diagram on the fan shroud. This will show you the location of the alternator and the serpentine belt tensioner.
Pull the serpentine belt tensioner away from the serpentine belt with the serpentine belt tool far enough to allow you to dislodge the belt from the alternator pulley with your other hand.
Unplug the wiring harness from the back of the alternator by hand. Remove the ground harness from the alternator with the socket set.
Unbolt the alternator from the alternator bracket with your socket set. Lift the old alternator out of the bracket by hand.
Compare the old alternator to the replacement alternator before installing the replacement. Make sure they're both physically identical before continuing. If not, take them both to the parts store to match up a proper replacement.
Set the replacement alternator in the alternator bracket by hand. Bolt it in with the socket set. Plug the wiring harness in by hand and bolt the ground harness to the back of the alternator with the socket set.
Install the serpentine belt on the replacement alternator in reverse of how you removed it from the old alternator.
All the best. Elect_Comp

How do you get the alternator out of a 2003 Focus SE, 16V Zetec DOHC?


Disconnect battery ground cable
Remove the ground wire (black) from the alternator
Disconnect the positive wire (red wire held on by a retaining nut) from the back of the alternator
Now disconnect the wire harness from the alternator
Remove the drive belt
NOTE: Some models use a belt tensioner that applies tension to the drive belt.
The best tool to use for this job is the serpentine belt too.
If you can borrow one from a neighbour you can get one at PartSource. (Part# 648451)
On other models you will have to loosen the adjusting bolt on the alternator bracket.
If you're not sure about how to remove the drive belt, visit your local PartSource for free print outs of car specific instructions.
Take off the mounting bolts from the alternator bracket
Now remove the alternator from the engine compartment

Installing Your New Alternator
Put the alternator in the engine compartment
Install the mounting bolts that connect the alternator to the alternator bracket
Connect the alternator wiring harness
Now connect the positive wire to the alternator
NOTE: Your new alternator should come with a retaining nut.
Remember to remove the nut before you install the positive wire.
If it doesn't keep the old nut.
Connect the ground wire to the alternator
Now install the drive belt
This is a great time to replace your old worn out belt. When inspecting your old belt look for signs of cracking, oil soaked, hard glazed, splitting or fraying.
All these signs mean it's time you replaced your drive belt.
If your vehicle no longer has the belt routing diagram under the hood, visit your local PartSource for a free print out of the belt routing diagram.

Where is the tension pully on a 1993 ford taurus 3.0 motor


there is no spring tensioner on some of the 3.0 engines. See instructions below. I will paste a pic on the version that DOES have a tensioner at the bottom of this post.

3.0L Engine-Except SHO
ALTERNATOR BELT WITHOUT AUTOMATIC TENSIONER

  1. Loosen the adjusting arm and pivot bolts.
  2. Turn the alternator belt adjusting screw counterclockwise until the old belt can be removed.
  3. Remove the belt.

To install:
  1. Install the new belt over the pulleys. Check that all the V-grooves make proper contact with the pulleys.
  2. Adjust the belt tension, then tighten the adjusting arm and pivot bolts.

3.0L SHO Engine
ALTERNATOR BELT
See Figure 2
  1. Loosen the nut in the center of the idler pulley.
  2. Loosen the idler adjusting screw until the old belt can be removed, then remove the belt.

To install:
  1. Install the new belt over the pulleys in proper contact with the pulleys.
  2. Adjust the new belt to specifications as follows: Turn the idler pulley nut to the right to tighten the belt to a specification of 220-265 lbs. (980-1180 N). Torque the idler pulley nut to 25-37 ft. lbs. (34-50 Nm).

POWER STEERING AND AIR CONDITIONING BELT
See Figure 2
  1. Remove the alternator belt.
  2. Loosen the nut on the tensioner pulley.
  3. Turn the belt adjusting screw on the tensioner counterclockwise until the belt can be removed, then remove the belt.

To install:
  1. Position the new belt over the proper pulleys, making sure the V-grooves are properly seated.
  2. Install the alternator belt.
  3. Adjust the power steering and air conditioning belt to a specification of 154-198 lbs. (690-980 N) with a belt tension gauge.
  4. Adjust the alternator belt.
3.0L Engine (Except SHO) and 3.8L Engine
VEHICLES THROUGH 1993 WITH AUTOMATIC TENSIONER

See Figures 4 and 5
  1. Insert a 1 / 2 in. breaker bar into the square hole in the tensioner.

On the 3.8L engine, the tensioner has a1/2in. square hole cast into the rear of the tension arm directly behind the pulley. On the 3.0L engine, the1/2in. square hole is cast into the spring housing on the front of the tensioner.
  1. Rotate the tensioner clockwise and remove the belt.

Fig. Fig. 5: 3.8L belt schematic-1993 shown

  2. Rotate tensioner counterclockwise and install the belt over the alternator pulley. Make sure that all the V-grooves make proper contact with the pulleys.

Engine running hot after a new alternater was installed


Although I CAN'T see how a new alternator would have anything to do with over heating except if it was the wrong one or incorrectly installed , the belt it rides on needs servicing(worn , to tight or too loose).
Maybe the wires on the back of the alternators are corroded not letting full B+ go to where its needed.
A visual inspection and a few simple test with a voltmeter should do the trick.
