Similar to my Bonneville. There is a tensioner pully on the left front of the motor. Take a wrench (I think 15mm) and place on the bolt head of the pulley. You should be able to move assembly so you can take the belt off.

How to replace a 1998 Ford contour alternater


The Contour alternator is somewhat harder to remove and replace than many cars. The 2.5-liter V6 engine is especially difficult, requiring removal of the right half-shaft to gain access.

WARNING!: ON BOTH ENGINES, BE CERTAIN TO REMOVE THE NEGATIVE BATTERY CABLE! FAILURE TO DO SO CAN RESULT IN DAMAGE AND/OR INJURY!

2.0 Liter engine (4-cylinder)

1. Disconnect the negative battery cable.
2. Remove air intake resonators.
3. Remove the air cleaner-to-throttle body tube and the mass airflow sensor.
4. Unplug the connectors and remove the cables from the alternator.
5. Raise and support the vehicle.
6. Release the drive belt tensioner and remove the drive belt from around the alternator. (It is not necessary to remove the drive belt from the engine.)
. Remove the alternator mounting bracket bolts and remove the mounting bracket.
8. Lower the vehicle.
9. Remove the power steering pressure hose bracket retaining nut and bolt and remove the bracket with the hose from the engine lifting eye.
10. Remove the alternator mounting bolts and remove the alternator from the vehicle.
11. To install, reverse the procedure.
==================================================
2.5 Liter engine (V6 engine)

1. Disconnect the negative battery terminal.
2. use a box-end wrench to turn the tensioner pulley clockwise to release tension on the belt. Remove the drive belt from around the alternator. (It is not necessary to remove the drive belt from the engine.)
3. Raise and support the vehicle.
4. Remove the wheel.
5. Remove the wheel well splash shield assembly.
6. Disconnect the outer tie rod from the knuckle assembly, then remove the hub nut from the hub.Tap on the outer spline of the half shaft to make sure it is separated from the hub. Use a hammer and a block of wood to avoid damaging the spline by directly hammering it.
7. Remove the front exhaust Y-pipe from the exhaust system.
8. Unplug all the wires and connectors attached to the alternator.
9. Remove the retaining bolts from the alternator brace and then remove the brace.
10. Remove the halfshaft by pushing out on the knuckle to separate it from the hub and then prying it out of the transaxle with a large pry bar. (Be sure to set a pan beneath the transaxle to catch the fluid that will drain out.)
11. Remove the alternator mounting bolts and remove the alternator from the vehicle.
12. To install, reverse the procedure.


Good luck!

How to remove belts from 1994 dodge caravan 2.5 liter


Drive Belts

Print


INSPECTION

See Figures 1, 2, 3, 4 and 5
Check the condition and tension of all drive belts every 12,000 miles, or at least once a year. Loose drive belts can lead to poor engine cooling and diminished alternator, power steering pump, air conditioning compressor, or emission air pump output. A belt that is too tight places a strain on the bearings in the driven component.

Fig. Fig. 2: An example of a healthy drive belt


0900c15280215ae6.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 3: Deep cracks in this belt will cause flex, building up heat that will eventually lead to belt failure


0900c15280215ae7.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 4: The cover of this belt is worn, exposing the critical reinforcing cords to excessive wear


0900c15280215ae8.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 5: Installing too wide a belt can result in serious belt wear and/or breakage
Replace any drive belt that is glazed, worn, cracked, or stretched to the point where correct adjustment tension is impossible. If two belts are used to drive a component, always replace both belts when replacement is necessary. After installing a new belt, run the engine for ten minutes, shut OFF the engine and recheck the belt tension. Readjust if necessary.


ADJUSTMENT

Fig. Fig. 10: Engine belt tension chart-1994-95 models
Two popular methods of checking drive belt adjustment are; the Belt Tension Gauge Method and the Belt Deflection Method. The former requires a special gauge and the latter requires a straight edge and scale or just a good eye for measurement. The deflection method will be used in the following belt replacement instructions. A rule of thumb for checking belt tension by the deflection method is to determine the midpoint between two pulleys of the drive belt and press down at that point with moderate thumb pressure. The belt should deflect to the measurement indicated in the following installation procedures. Adjustment is necessary if the belt is either too loose or too tight.

WARNING A belt adjustment which is either too loose or too tight will eventually damage the accessory that belt is driving. A too loose adjustment allows free-play in the belt which could transfer a whipping motion or shock to the accessory drive pulley. Similarly, a belt which is too tight will preload the accessory bearings, leading to early failure.


REMOVAL & INSTALLATION

See Figure 11
Raise the front of the vehicle, support on jackstands and remove the lower splash shield if access is hampered due to space limitations when changing drive belts.

Serpentine belt diagram for a 2003 Chevy unpalatable 4.3


Pop the hood of the car and locate the serpentine belt routing diagram. The diagram on the 2003 Chevrolet Impala is on top of the fan shroud. The diagram will be a picture of all of the accessory pulleys and how the serpentine belt is routed among the pulleys. This diagram will give you the exact direction for routing the new belt onto the pulleys. If you cannot find a serpentine belt routing diagram, take a notepad and pen and draw out the exact routing diagram of the old belt across the pulleys.

  • 2 Locate the serpentine belt tensioner. It is located below the alternator on the left front side of the engine. The tensioner on the 3.4 liter, 3.5 liter and the 3.9 liter engines will require a 3/8 ratchet to release the belt tensioner. The 3.8 liter engine will require a ratchet and a 15 mm socket for the belt tensioner. Rotate the belt tensioner clockwise to loosen and remove the belt from the belt tensioner pulley.
  • 3 Slide the old belt from the belt tensioner pulley. Remove the belt from the remaining pulleys and pull the belt from the engine compartment.
  • 4 Route the new belt across the crankshaft pulley first. The crankshaft pulley is the big pulley on the bottom of the engine in the center. Then route the serpentine belt across the remaining pulleys as directed by the serpentine belt routing diagram. Leave the belt tensioner pulley for last.
  • 5 Rotate the belt tensioner clockwise again to relieve the tension and slide the new belt across the top of the belt tensioner pulley. Release the belt tensioner and the belt will tighten up as the tensioner applies pressure to the belt. Make sure the new belt is properly seated in all the pulleys.
  • 6 Crank the engine and inspect the belt again to make sure that it stays seated in the pulleys.

    Which motor mount bolts do I need to remove to threat the serpentine belt on a 99 Cutlass 3.1 liter, or do I need to remove any? Thanks a lot.


    my manual indicates this is only required on 97-98 models. you should not have to remove any motor mounts. Here is the procedure from autozone.com:

    1. Disconnect the negative battery cable.
    2. If necessary on the 1999-00 3.1L engine, remove the coolant recovery reservoir.
    3. Remove the belt guard located on top of the belt, between the water pump and the power steering pump, if necessary on the 3.1L engine.
    NOTE: For the 3.1L engine use a long 3 / 8 inch drive ratchet or breaker bar.
    1. For the 2.4L engine and 1999-00 3.1L engine, remove the drive belt from the vehicle.
    1. Rotate the belt tensioner.
    2. Place the drive belt around the pulleys according to the belt routing diagram.
    1. Slowly release the belt tensioner.
    2. Check belt for proper routing. Also, make sure belt is not twisted.
    3. If removed, install the belt guard and/or coolant recovery reservoir, as applicable.
    4. Connect the negative battery cable.
    WARNING Before starting engine, make sure the belt is not incorrectly routed or twisted. Check to make sure no stray tools are in engine compartment. Starting the engine with an improperly installed belt may damage belt, engine, or accessories.


    CAUTION Incorrectly installed belts and stray tools may cause flying debris. Clear area before starting engine.

    1. Start the engine and check for any belt noises such as whine, rumbling, or squeal.

    How do you change serpatin belt on 98 buick lesabre with a 3.8 liter engine..it looks like you have to take motor mount loose?


    The manual has this step in it: "remove the engine mounting bracket lower nut, stud and spacer. Carefully lower the vehicle."

    It never said to raise the vehicle, so I think there is an error here.
    However, it is an indication that the belt needs to slip under the motor mount.

    Recommend you put a floor jack under the engine, prop it up, remove the mount stud, and lower or raise the engine as needed to get the belt out.

    If you don't have a floor jack, you can accomplish the same using the car jack on the regular jack point, jacking it up, and then putting some bricks and 2 by 4s under the pan. Then let the car down until the engine touches. Take the nut off the stud and raise or lower the car as needed to open a gap for the belt to pass thru.

    OK? If you have more questions, please let me know.

    How do you replace the serpintine belt on a 1998 contour?


    Open the hood and locate the belt tensioner. The serpentine belt drive is located on the front of the engine on the passenger side of the engine compartment. The spring-loaded belt tensioner on the 1998 Contour is located slightly to the left of and below the water pump pulley
    Release the tension on the belt using the serpentine belt removal tool. On vehicles equipped with the 2.5 liter V-6 engine, snap the 3/8 inch-drive adapter onto the removal tool. Slip the tool into the square, 3/8-inch hole in the end of the tensioner arm. Rotate the tensioner clockwise to release the tension. While holding the tensioner back, remove the belt from one of the pulleys. Release the tensioner, remove the belt from the remaining pulleys and pull it out of the engine compartment
    Snap a13 mm socket adapter into the belt removal tool for the 2.0 liter, four cylinder Contour. Place the tool onto the 13 mm bolt that holds the tensioner pulley to the tensioner arm and rotate the tensioner clockwise. While hold the tensioner back, slip the belt off one of the pulleys. Release the tensioner, slip the belt from the remaining pulleys then remove it from the engine compartment
    Route the new belt around the pulleys, according to the belt routing guide. The belt routing guide on the 1998 Contour is located on a decal on the left (passenger side) strut tower. If this decal is missing, or unreadable, the belt routing guide can also be found in your service manual. Rotate the tensioner pulley one more turn to allow the new belt to slip under the tensioner pulley.
    Check the belt for proper alignment on the pulleys. It should lay flat on the pulley and not overhang the edges. If the belt must be repositioned, release the tensioner and reposition as needed.
