13. When the auto tensioner measurement is correct, install or connect the following:
    
    Engine mount Upper and lower timing belt covers Belt tensioner pulley Power steering pump pulley Crankshaft pulley Idler pulley Accessory drive belts Engine cover Negative battery cable
    
14. Reprogram the radio anti theft codes.

A listing of serpentine belt diagrams can be found HERE. It will show you the location of the tensioner pulley, which must be loosened in order to remove and install the new belt. When the new belt is on, just readjust the tension via the tensioner pulley.

locate tensioner pulley; release tension from belt; remove belt; make sure not to forget how the belt is routed; route belt around all pulleys but tensioner; put tension on tensioner pulley; route belt over tensioner pulley

4. Loosen generator mounting bolts and adjusting bolt.
5. Remove generator bolts.
6. Remove water pump pulley.
7. Remove crankshaft pulley and timing belt guide plate.
8. Remove upper and lower timing belt covers.
9. Turn crankshaft so that timing mark on timing belt pulley is aligned with timing mark on engine.
10. Check that "I" mark on intake camshaft pulley is aligned with mark on cylinder head cover and "E" mark on exhaust camshaft pulley is aligned
with mark on cylinder head cover.
NOTE: Do not move camshaft or crankshaft once timing marks have been correctly positioned.
11. Loosen tensioner pulley lock bolt.
12. Protect timing belt with a rag.
13. Remove tensioner pulley.
14. Remove timing belt.
NOTE: Mark the direction of timing belt rotation (on the timing belt) for proper reinstallation.
INSPECTION
NOTE: Never forcefully twist, turn inside out or bend timing belt. Do not allow oil or grease to come in contact with timing belt.
1. Replace timing belt if it is contaminated with oil or grease.
2. Check timing belt for uneven wear, fraying, peeling, cracking and hardening. Replace timing belt as necessary.
3. Bend timing belt into a "U" shape as shown in figure. Distance "A" must be at least 1.0 inch (25 mm).
4. Inspect both idler pulley and tensioner pulley for uneven wear and smooth bearing operation.
5. Inspect camshaft pulleys and timing belt pulley for broken teeth or damage.
NOTE: Replace any component that shows damage, excessive wear, or that appears prone to a possible failure.
INSTALLATION
1. Install tensioner pulley.
NOTE: Replace tensioner spring whenever timing belt is replaced.
2. Pull tensioner pulley to its furthest point and tighten lock bolt.
3. Check that timing mark on timing belt pulley is aligned with timing mark on engine.
4. Check that "I" mark on intake camshaft pulley is aligned with mark on cylinder head cover and "E" mark on exhaust camshaft pulley is aligned
with mark on cylinder head cover.
NOTE: If existing timing belt is being reused, install belt in proper rotation direction marked prior to removal.
5. Install timing belt onto timing belt pulley first, then idler pulley, exhaust camshaft pulley, intake camshaft pulley, and tensioner pulley in that
order.
6. Check that there is no looseness in belt between idler pulley and exhaust camshaft pulley or between intake and exhaust camshaft pulleys.
7. Loosen tensioner pulley lock bolt and allow tensioner spring to apply tension to timing belt.
NOTE: Do not add additional tension.

8. Tighten tensioner pulley lock bolt to specified torque.
Tightening torque: 28 - 38 ft. lbs. (38 - 51 Nm, 3.9 - 5.2 kg-m)
9. Rotate crankshaft two full revolutions (clockwise only) and align timing mark on timing belt pulley with timing mark on engine block.
10. Check that "I" mark on intake camshaft pulley and "E" mark on exhaust camshaft pulley are aligned with marks on cylinder head cover.
11. If they are not aligned, remove timing belt and start process from tensioner installation.
12. Measure timing belt deflection by applying moderate pressure midway between camshaft pulleys. If deflection is not correct, repeat from
tensioner installation.
Deflection pressure: 22 lb. (98 N, 10 kg)
Deflection: 0.39 - 0.50 inch (11 - 13 mm)
13. Install lower and upper timing belt covers in that order.

14. Install timing belt guide plate and crankshaft pulley.
Tightening torque: 9.0 - 12.6 ft. lbs. (12.3 - 17.2 Nm, 1.3 - 1.8 kg-m)
15. Install water pump pulley.
Tightening torque: 9.0 - 12.6 ft. lbs. (12.3 - 17.2 Nm, 1.3 - 1.8 kg-m)
16. install generator belt and adjust the tension.
17. Install P/S and/or A/C drive belt and adjust the tension.
18. Connect negative battery cable.

Removal & Installation

1. Disconnect the negative battery cable.
   
2. Rotate the auto tensioner clockwise to release tension, then remove the drive belt.
   

To install:

1. Install drive belt (A). Route the belt over the components in the following order: Crankshaft pulley → A/C pulley → idler pulley → generator pulley → water pump pulley → P/S pump pulley → tensioner pulley.
   
2. Rotate auto tensioner arm in the counter-clockwise moving auto tensioner pulley bolt with wrench.
   
3. After putting belt on auto tensioner pulley, release the auto tensioner pulley slowly.

Your truck has one belt and one idler pulley. To tighten it you will need a large bar (a breaker bar, crowbar or large screwdriver will work) Loosen the idler pulley bolt (not all the way) just enough to break it loose then use the bar against the pulley to tension the belt. If there are parts missing from the idler pulley, a new one must be purchased.

good luck,i hope this help pls dont forget to rate me thanks

UNDER THE HOOD IS A DIAGRAM OF HOW THE BELT IS ROUTED. TAKE NOTE OF THE WHITE STICKER ON THE FAN SCHROUD, JUST ABOVE THE FAN. THE TENSIONER PULLEY IS THE ONE YOU NEED TO ROTATE IN ORDER TO RELEASE THE TENSION ON THE BELT FOR REMOVAL. USING A 15 OR 16 MM SOCKET, ROTATE THE TENSIONER UNTIL YOU RELIEVE THE TENSION AND SLIDE THE BELT OFF ONE OF THE SMOOTH PULLEYS. THEN RELEASE THE RATCHET EASY SO IT DOESN'T SPRING BACK UP. UNRAVEL THE BELT AND INSTALL THE NEW ONE USING THE DIAGRAM. JUST A HINT: IF THE PULLEY HAS RIDGES THEN THE BELT HAS TO BE ON THE RIDGED SIDE OF THE BELT, IF IT HAS A SMOOTH PULLEY, THEN IT RIDES ON THE OUTSIDE OF THE BELT. WHEN YOU ALMOST HAVE THE BELT ON THE LAST PULLEY, ROTATE THE TENSIONER AGAIN AND SLIDE THE BELT ON THE LAST PULLEY. IT HELPS IF THE LAST PULLEY IS A SMOOTH ONE. HOPE THIS HELPS ENOUGH TO FINISH THE JOB. PLEASE KEEP ME POSTED. THANKS FOR AN HONEST RATING AND FOR USING FIX-YA. GOOD LUCK.

There's an automatic belt tensioner pulley that keeps the proper tension on the belt. 
To remove the belt, get a wrench (or the Ford tool) on the center bolt of the tensioner - its the only pulley that doesn't attach to anything, ie power steering,alt, water pump etc - and turn it away from the belt. When its loose enough, you can remove the belt. Remember how it goes on!

There is a square hole for a 1/2 socket or a bolt head on the tensioner pulley to connect to and pull the pulley away from the belt to enable removing the belt from the closest pulley you can with your free hand.

This can be insane and very time consuming. There were 3 types of engines made for this year. You need to know which one. All will take a 15mm offset box wrench. All types will need to be turn clockwise?

Good luck and hope this helps.

If you decide to do this yourself you will need a set of open end wrenches. Be sure to draw a diagram showing exactly how the drive belts are situated around the pulleys now so you don't make a mistake. Then loosen the belt tensioner and remove the old belts.

OR go to an auto zone store and the sales person will assist you with this for no charge as long as you buy the belts there.
