Need the spec on installing a tension pully for a 2003 ford taurus


Not sure what spec your looking for. I replaced the tensioner pully on my F-150 302 last year though. And basically the bolt is left hand thread and turning the bolt gives the slack in belt needed to take belt off, and put back on. Hope this helps.

I cant move the belt tensioner enough to get belt over alternator pully? Is there a trick?


Put the belt onto all groved pulleys first, then un-tension the tensioner/idler pulley and slide the belt onto it (the tensioner/idler pulley should be smooth with no lip for the belt to go over).

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


To install:

  1. Install the drive belt over all the pulleys, except for the alternator pulley on the 3.0L engine for vehicles through 1992, or the idler pulley for 1993 3.0L vehicles.
  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.
  4. For 1993 3.0L vehicles, install the drive belt over the idler pulley.

Do you have a way to find the route for a 1993 Ford Escort Serpentine Belt?


FOR A 1.9L ENGINE. CANT SEND PIC, START BY PUTTING BELT OVER ALTERNATOR PULLY,THEN TO THE RIGHT OF POWER STEERING PUMP PULLY FROM THERE TO THE LEFT SIDE OF THE IDLER PULLY , THEN UNDER THE A/C COMPR PULLY AND UNDER THE CRANK PULLY RELEASE TENSION ON TENSIONER BELT GOS UNDER TENSIONER.

Remove water pump


Disconnect battery earth lead. Do not turn crankshaft or camshaft whn timing beld removed. Remove spark plugs to ease turning engine. Turn engine in normal direction of rotation (unless otherwise stated) Do not turn engine via camshaft or other sprockets. Observe all tightening torques. Remove engine, remve RH engine mounting. Remove auxiliary drive belts, water pump pulley, crankshaft pulley, timing belt upper cover, timing belt lower cover. Turn crankshaft clockwise to TDC on No. 1 cylinder, slacken tensioner bolts 5 & 6. Move tensioner away from belt and lightly tighten bolts. Remove timing belt. Remove water pump and replace with new one. Suggest to replace cambelt as well.
Installation
Ensure timing marks aligned3 & 4. Fit timing belt in anti-clockwise direction, standing at crankshaft sprocket. Ensure belt is taut between sprockets on non-tensioned side. Slacken tensioner bolt 5. slacken tensioner bolt 6. Allow tensioner to operate. Tighten tensioner bolt 6. Tighten tensioner bolt 5. Turn crankshaft on turn clockwise. Ensure crankshaft sprocket timing marks aligned 4.
Slacken tensioner bolt 5. Slacken tensioner bolt 6. Allow tensioner to operate. Tighten tensioner 6. Tighten torque: 20 - 26 Nm. Tighten tensioner bolt 5. tighten torque: 20 - 26 Nm. Apply thumb pressure to belt at middle. Approximately 5kg. Belt should deflect to 1/4 of tensioner bolt head width 7. Belt tention can also be set using burroghs (BT-33-73F) tension gauge 10 at middle. Turn crankshaft 90 ° anti clockwise. Check belt tension is 9.5 16,5kg (engine must be cold). Install components in reverse order of removal. Fit cranckshaft pully. Tighten crankshaft pully bolts 8. G4-J: Tightening torque: 12-15Nm.
G4-N/G4-k: Tightening torque: 10-12Nm
G4EA: Tighten crankshaft pully bolt 9. Tighten torque: 140-150Nm.

Replace a serpentine belt on a 97 ford taurus


use a 15mm box wrench on the nut retaining the tensioner pulley to pry the tensioner 'arm' against the spring to release belt. note belt routing on decal under hood,or make a sketch,to aid in replacement.
on OHV engine rotate clockwise
on OHC rotate counter clockwise
be sure belt is completely seated on pulleys

Belt inst


For the 3.0L Vulcan, you have a tensioner that is located just below the power steering pully. Use a 15mm wrench or the 15mm shallow well socket that comes in a Serpentine Belt tool to push the tensioner toward the rear of the engine compartment. Take the old belt off and route the new belt. The belt begins at the crankshaft pully, goes under and around the a/c compressor, up around the power steering pump, around (with the flat edge) the idler pully, around the alternator, the flat edge then sits against the tensioner and back around to the water pump pully. You should have a belt routing diagram on the underside of the hood just above the serpentine pully assembly.

Try this procedure.

To replace a worn belt, locate the idler or generator pulley.

0900823d8004ed45.jpg


Loosen the hold-down fastener for the idler or generator pulley.

0900823d8004ed46.jpg


Pry the idler or generator pulley inward to release the belt tension and remove the belt.

0900823d8004ed47.jpg


Match the old belt up for size with the new replacement belt.

0900823d8004ed48.jpg


Observe the belt routing diagram in the engine compartment.

0900823d8004ed49.jpg


Install the new belt over each of the drive pulleys. Often the manufacturer recommends a sequence for feeding the belt around the pulleys.

Install the belt squarely in the grooves of each pulley.

Before adjusting belt tension, check for proper pulley alignment. This is especially critical with serpentine belts. Measure the belt deflection in its longest span. If a belt tension gauge is available, use it and compare the tension to specifications.
If a belt is too tight, wear to bearings for the water pump, alternator, and engine crankshaft can result.
Some late-model Chrysler engines require a torque reading to be taken when tension is applied to the generator drive belt. This is especially important on the longer, multiribbed V-belts.

0900823d8004ed76.jpg


Pry the idler or generator pulley to adjust the belt to specifications.

0900823d8004ed77.jpg


Tighten the idler or generator pulley fastener.

0900823d8004ed78.jpg


Start the engine and check the belt for proper operation.

Any more questions please ask. Good luck.
