No, the tensioner is spring loaded and is supposed to keep the belt tight. The spring could be getting weak, or the belt could have stretched. Or it could be glazed and slipping on the pulleys.
The reason it squeals on startup is because of the extra load put on the alternator, and the belt is cold.

SOURCE: Serpentine Belt on a 1999 Ford Escort ZX2

If you have a book picture your are screwed. You do have a tensioner but it is between air con and powersteering pullys. In front from under you can put 15mm wrenchopend with a nother for leverage pull center bolt down to release tension. simple.

Try removing the belt and turning each pulley by hand. If everything is smooth and free, with the belt still off, drive down the block once and see if the noise is there (this will eliminate all rotating accessories on the front). If you hear the noise, then there is a problem deeper inside. Oil pressure is good? Dont' forget when doing this, you will have no power steering, so be careful.

What would cause my belt to not spib & squeal realy loud on my 93 Ford mercury topez


If the belt is not turning, there will be a seized pulley. Possible alternator.. power steering.... water pump... tensioner.... idler pulley ... AC compressor seized. The belt will need to be removed and all the pulleys spun by hand to isolate tone that may be seized

High pitched screech when accelerating.


Take the drive belt off and turn all pulleys by hand to see if any have excessive resistance. You failed to mention power steering, and a/c (if equipped). Both can cause belt squeal.

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.
  3. On the 3.0L engine, install the alternator belt for vehicles through 1992.

How do you tighten the fan belt?


Focuses use an automatic belt tensioner which has no adjustment (as its spring loaded) if your belt is not tight enough replacement of the tensioner could be necessary..if you're asking due to a squealing problem check the pulley on the tensioner and the idler pulley..they are a common part to need changing

How do I asjust the serpentine belt on a 2005 ford freestar?


It should not require any adjustment. the right tension is provided by the idler pully. If you want to release the tension for serpentine removal or examination release the tension on the idler pulley in the rear of the motor, spin the nut in the center like you were tightening, and the pressure will be released from the serpentine belt. Reversely, the appropriate tension will be given using the same way when the strap is reinstalled.
