There is a tensioner for the serpentine belt, it is spring loaded so it adjusts by itself. if the belt is loose then the spring in the tensioner has gone south. you need a new tensioner, about 50 bucks but replacing it is beyond normal owner servicing. there are many videos of folks replacing tensioners on youtube. note the tools they have, and most videos are shot from under a lift. if you have all those on hand, then you would not have asked the question. buy the part and take it to a repair shop.

Need to know tbe steps to replace the belts on 2009 kia sportage. Every video i play stop at the spot i am at for some reason. Really need to get my car back on the road asap

There should be 2 belts. Remove the plastic under belly cover and the side cover to expose the under and side where the belts are located. The alternator has a tension adjustment bolt that tightens up the belt by moving the alternator, Loosen this bolt so you can slide the alternator and remove the belt. The second belt has a tensioner pulley and an adjustment bolt like the alternator. Loosen this bolt to get slack in the belt to remove. Install the back belt and tighten the tensioner pulley. Don't over tighten, You should be able to move the belt by about 1 cm with 10-15 kgs of force at the longest free section. Once tightened, install the outer belt and tighten using the alternator adjustment bolt. Again, about 1 cm movement with 10-15 kgs of force. I usually start the car at this point to be sure the belts are on correctly and everything looks good. Install the plastic covers.

How do I locate the tensioner for the alternator belt on a 2003 kia spectra?

I wondered the same thing and looked for days on end. To my surprise, there is no tension pulley for the 2003 Kia Spectra. The Kia 4 cyl has two (2) belts. The outside belt services the power steering and air conditioning. The inside belt (the one you want to service) services the alternator and water pump. The alternator tension is set by two (2) adjustment screws located on the alternator. One screw is used as a locking bolt and the upper bolt is used as the adjuster. You must first loosen the locking bolt which is located between the belt and the alternator housing. Loosen about 6 to 8 travels of the wrench (size 13mm), then tighten the upper bolt until you have no more than 1/2 inch of movement in the belt when you press down. After the correct tension is achieved, tighten the locking bolt and your done. As long as you're down there, you might as well check the outer belt as well. Same principle, one locking and one adjuster. Good Luck, Fred

I am trying to hange the serpentine belt on my 09 lancer rallyart and it keeps slipping off

Locate the two belts on the left side (passenger side) of your Mitsubishi Lancer. The outer belt is a serpentine belt, operating four pulleys and the inner belt is your alternator belt.

  • 2 Follow the serpentine (outer) belt to the three pulleys lined up vertically near the front of the engine compartment. Locate the middle pulley, which is the tension pulley for the belt.
  • 3 Loosen the bolt on the middle pulley with a socket wrench by turning counter-clockwise. Do not remove the bolt, just turn it a couple of times. Loosen the tensioner bolt on the side of the of the pulley, facing the front of the vehicle.
  • 4 Remove the serpentine belt and then loosen the bolt on the alternator. With the alternator loose, move it forward so that the alternator belt loosens up and then remove belt from the pulleys.
  • 5 Install the new alternator belt by placing it over both inside pulleys. Tighten the tension on the alternator belt by moving the alternator back and keeping tension on it by holding it back with a long screwdriver. While the alternator belt is tight, use a socket wrench to tighten up the bolt on the alternator.
  • 6 Place the serpentine belt back on the pulleys and then use a socket wrench on the bolt on the front of the tension pulley. Once the serpentine belt is tight, tighten up the bolt in the middle of the tension pulley.
  • 7 Start the Mitsubishi Lancer's engine to test the alternator belt and make sure it is working properly. Once you have verified it is working, turn the engine off.

    HOW TO INSTALL ALTERNATOR BELT DIAGRAM

    ALTERNATOR/WATER PUMP DRIVE BELT(courtesy of autozone)

    On most of the 1981-88 model year engines covered in this information, the alternator/water pump drive belt is tensioned by a screw type tensioner, which makes precise tension adjustment easy.

    1. On 1981-87 models, loosen the locknut, located on the locking screw or lockbolt-located in a slotted portion of the outboard alternator mounting bracket.
    2. On 1988 models, loosen the T-bolt, located in the center of the disc shaped portion of the outboard alternator bracket.
    3. Tighten or loosen the drive belt tensioning bolt. This bolt is tightened to increase belt tension and loosened to decrease it.
    4. When the belt tension is correct, tighten the lockbolt.

    this is the 2.2 gas engine, if its different here is a link to the info at autozone

    How do u change a serpentine belt for a 1999 ford escort zx2

    ADJUSTMENT 1.8L Engines ALTERNATOR AND WATER PUMP BELT
    1. Loosen the alternator adjusting bolt.
    2. Raise and safely support the vehicle.
    3. Loosen the alternator mounting bolt. NOTE: Do not pry against the stator frame. Position the prybar against a stronger point, such as the area around a case bolt. Fig. 1: A belt tension gauge should be placed on the longest span of the belt to check tension — 1.8L engine 90981g05.gif

    4. Position a suitable belt tension gauge on the longest accessible span of belt and tighten the belt.
    5. Adjust the tension to 86–103 lbs. (383–461 N) for a new belt or 68–86 lbs. (304–383 kg) for a used belt.
    6. If a belt tension gauge is not available, adjust the tension to 0.31–0.35 in. (8–9mm) deflection for a new belt or 0.35–0.39 in. (9–10mm) deflection for a used belt.
    7. Tighten the alternator adjusting bolt to 14–19 ft. lbs. (19–25 Nm).
    8. Tighten the alternator mounting bolt to 27–38 ft. lbs. (37–52 Nm).
    9. Lower the vehicle. Fig. 2: Alternator and water pump pulley belt routing — 1.8L engine 90981g06.gif
    POWER STEERING PUMP BELT
    1. Raise and safely support the vehicle.
    2. Loosen the power steering pump mounting bolt and nuts.
    3. Adjust the power steering pump and, if equipped, the air conditioning compressor belt tension by turning the pump adjusting bolt. Fig. 3: Power steering pump belt routing and locations of the mounting bolts, nuts and adjusting nut — models without A/C 90981g07.gif

    4. Tighten the power steering pump mounting nut near the pump adjusting bolt.
    5. Position a suitable belt tension gauge on the longest accessible span of belt and tighten the belt.
    6. Adjust the tension to 110–132 lbs. (491–589 N) for a new belt or 95–110 lbs. (422–491 N) for a used belt.
    7. Check for proper belt deflection. For a new belt (one with less than 10 minutes of run time), the deflection should be 0.31–0.35 in. (8–9mm). For a used belt (one with more than 10 minutes of run time), the deflection should be 0.35–0.39 in. (9–10mm).
    8. Tighten the power steering pump mounting nut, located near the adjusting bolt, to 27–38 ft. lbs. (37–52 Nm).
    9. Tighten the pump mounting bolt behind the pulley to 27–40 ft. lbs. (36–54 Nm), and the remaining pump mounting nut to 23–34 ft. lbs. (31–46 Nm).
    10. Lower the vehicle. Fig. 4: Power steering pump belt routing and locations of the mounting bolts, nuts and adjusting nut — models with A/C 90981g08.gif
    1.9L Engines The accessory drive belt for 1.9L engines has no provision for manual belt adjustment, since these engines use an automatic belt tensioner. Drive belt slack is taken up by the automatic tensioner. NOTE: Movement of the automatic tensioner assembly during engine operation is not a sign of a malfunctioning tensioner. This movement is the tensioner self-adjusting and is required to maintain constant belt tension. Fig. 5: Drive belt routing — 1.9L engines 86751052.gif
    2.0L Engines The accessory drive belt for 2.0L engines has no provision for manual belt adjustment, since these engines use an automatic belt tensioner. Drive belt slack is taken up by the automatic tensioner. NOTE: Movement of the automatic tensioner assembly during engine operation is not a sign of a malfunctioning tensioner. This movement is the tensioner self-adjusting and is required to maintain constant belt tension. The belt tensioner has a belt length indicator. If the indicator marks are not between the MIN and MAX marks, the belt must be replaced. Fig. 6: Drive belt routing — 2.0L SOHC engine with A/C 90981g23.gif

    Trying to put belt back on and it has to loop over tensioner pulley?? how does that happen ?

    This sounds like a serpentine belt (has grooves on one side) - the smooth side of the belt will lay across the tensioner it's easier (usually) to run the belt around and use the tensioner to set the belt in place (use ratchet and socket).

    Or, start with the tensioner and use the alternator (loosen the alternator) to tighten the belt.

    Either way you choose, it's best to have two people do it - One hold the tensionor (or pries the altenator to tighten and tightens bolts on alternator) and the other puts the belt over the tensioner; then the person on the tensioner slowly lets off the pressure of the tensioner.

    Please let me know if you need further assistance.

    I have a 1991 dodge colt vista 2.0 l engine, and need to know where to get info on replacing ( how to or what to do ) the alternator belt. thanks

    There is a curved bracket that the alternator is bolted to. This allows you to adjust the belt tension. Loosen this bolt and locate the other bolt that mounts the alternator to your engine. Loosen this one, as well. Now swing your alternator in the direction that will allow you to free the belt and remove it. Put the new belt on and swing the alternator to get good tension on the belt. Tighten both of the bolts on the alternator, but leave them loose enough that you can still adjust the belt's tension. Now use a bar to pry the alternator in the direction that will increase the tension on the belt a little bit and tighten the bolt on the curved bracket with your free hand. Now, tighten the other bolt. Start the car and verify that the belt has decent tension and does not slip (this will cause premature wear, squealing and bad charging). If everything is good, you should be all set. If it is too tight or too loose, you will need to readjust the tension of the belt.

    Hope this helps,
    matt
