The tension on a serpentine belt is automatically set by the Idler Tension Pulley. If you find it is not correctly setting the tension, the the spring may be broken.

Serpentine belts have a pulley that is spring loaded. Tension is set automatically when the belt is installed.

There is no idle vacuum line on P/S. I don't know how you tightened a serpentine belt when their is no provision for doing that. The tension is controlled by the idler tension pulley. If you are referring to a normal drive belt, then set the deflection at mid point of the belt to approximately 1/4". Check with Chrysler for the exact specs on deflection.

This vehcile uses a serpentine belt. The belt tension is set automatically by the tensioner. If the tensioner is stuck and will not apply tension to the belt then it is defective and needs replacing.

a serpentine belt if installed correctly has a blet tensioner. this will apply correct tensionwithout any adjustments

Use a socket and ratchet on the belt tensioner pulley bolt. Pull the ratchet to the side to let tension from the belt. Remove the belt. Install the new belt ( a helper will make the job easier.) Release the ratchet to set the belt tension.

There are a few different ways to adjust the drive belt or V-belt tension in a vehicle. The most popular used nowadays is a serpentine belt that connects to and activates every pulley in the engine. These serpentine belts require no tension adjustment as they incorporate an automatic belt tensioner. This type of tensioner has an internal pre-set spring and applies the correct amount of tension to the belt. Some older vehicles and some imports may use a combination of V-belts and serpentine belts in offset pulleys still controlled by the crankshaft pulley. Most often, there are belt tensioners on these vehicles that allow proper tension to be adjusted.

If you just want it looser...its factory set....To remove it, locate the tension pulley and us a open face wrench to take off the tension...belt will come right off.

You have no "adjuster bolt". You have a serpentine drive belt and it's tension is maintained by an automatic belt tensioner. It is a pulley mounted on a housing containing a "clock spring" that keeps the belt under a pre-set tension and compensates for belt-wear. It is released by a special belt tool or a flex-drive handle. Mark---Raleigh, NC

must find the belt tension rotator and then either lossen it or use a crow bar to move tension arm . install the serpintine belt and at the same time the tension arm must move to alow the belt to set right on all pullies. it should be obvious as to how the belt goes and the arm,,,once motivated to move up tighten the belt once the install of the belt is done.

Loosen the belt tensioner. Make sure that the belt can be removed easily. Replace the belt with a new one. Check that belt is clean before installing. Clean the pulleys if you have to. Tighten the belt tensioner to set proper tension.

1. Make sure that when you purchase a new belt, they don't try to sell you the full size serpentine belt. 2. There is a diagram of the belt routing on your truck when you lift the hood. Follow that. 3. Unfortunately, you need to remove the serpentine belt to replace the air conditioning belt.... the belt routing for the serpentine belt is also shown on the diagram. 4. To remove the serpentine belt, get a ratchet set, and crank the "self tensioning" assembly to release tension on the serpentine belt, and remove the belt. 5. There is another "self tensioning" assembly for the air conditioning belt. Crank to place the new AC belt on and release. 6. Re-install the serpentine belt. This is an easy fix... it took me less than 20 minutes, I'm not a mechanic.

On top of the engine there is a serpentine belt (5 grooves). The tension is autmatically set by the belt tensioner. It is an arm with a pulley on the end of it. The other end has a 3/8 inch connector for a ratchet. Put a ratchet on the end of it and pull it towards you. This should relieve the tension enough to take the belt off the pulleys.

The serpentine belt has an easy adjustment. Loosen the nut holding the tensioner wheel and turn the adjusting screw until proper belt tension is achieved. Tighten tensioner wheel nut.

Disconnect battery find out how the belt has tension (i'm not familiar with that engine set up) and remove tension. Remove serpentine belt remove all bolts holding alternater on there are 2 wires connected to it: 1 has a nut that must be removed and the other is a plastic connecter install new part and replace everything you disassembled tip: draw a picture of serpentine belt routing (if there is no sticker with picture)

The serpentine belt tension is not adjustable. It is set by a spring loaded idler pully. "Idler" just means that it is not used to drive anything. It is spring loaded to tension the belt and control belt position. The bracket for the idler pully has a square hole in it that is used to compress the spring during belt installation or removal. You can put a 1/2" drive ratchet or breaker bar in the square opening and apply pressure against the spring to remove the old belt or install a new one. Ratchets and breaker bars are normally used with a socket to loosen nuts, but no socket is required to use them in the idler pully bracket. If your belt is making noise or looks loose it probably needs to be replaced. Typical belt life is 3-5 years. The tension is set with an automatic tensioner. It must be replaced.

The serpentine belt is usually the belt that winds over the pulley wheel that drives the alternator, which charges the battery. If the belt is missing or mis-routed, the alternator won't turn and the battery will not be recharged. If the belt is slipping on the alternator pulley, the battery may charge insufficiently or irregularly. Causes for a slipping belt include heavy wear, contamination with oil or other fluids, and misadjusted tension. There is usually a positioning arm connected to the alternator (and/or another pulley around which the belt travels) that can be, and must be, adjusted. Set it to apply enough pressure on the belt to provide the tension needed to drive all the driven pulleys without slipping. There are tools that will measure that tension and manuals that state the proper amount.

Loosen the central nut of the belt tension pulley. Loosen the tightening bolt. Remove the belt, install a new one. Set proper tension. Tighten the central nut.

Generally, serpentine belt systems have a spring loaded tensioner pulley in them that don't require adjustment. However if your belt is loose, look for an idler pulley (one that does not drive anything). These will sometimes have an adjustment on them. A word of caution, serpentine belts require a specific tension that, if adjustable, require specialized tools to set them. Too tight and you will wear components driven by the belt prematurely, too loose and there can be problems with a component in the system. If you are a proficient do-it-yourselfer, I would suggest buying a service manual and following the proper procedures outlined in there.

Put you car on jack stands, remove the right wheel. Loosen the tension pulley for the accessory belt (AC, alternator). Remove the belt. Loosen the tension pulley for the power steering, remove the belt. Install a new belt, and set proper tension. If you do not have a tool to measure tension, use rule of thumb. When the belt is under proper tension you should be able to twist only 3/4 of full twist. Do the same for the accessory belt.

Line up your timing marks on the cams and crank (install belt) and it will be in time, Turn the crank manually with a socket and breaker bar a couple revolutions to make sure the marks are still lined up after tighting the belt tension.

If your vehicle has an automatic belt tensioner with a serpentine belt, the belt is worn and needs to be replaced. On older models, the belt tension can be set by adjusting it at the alternator bracket. Loosen but do not remove the two bolts that hold the alternator in place (one at the bracket and one on the block) and pull the alternator to tighten the belt. Hold in position while re-tightening the bracket bolt then tighten the bolt on the block.

dont know about the petrol engines but I have a 1.9 tdi and you dont tension it it has an automatic tensioner when set in the correct position puts the correct tension on the belt it is spring loaded I cant remember exactly how it works but you should dor more research into this before attempting to tension a worn belt or changing one as a failed timimng belt can cause massive engine damage

to release tension on a serpentine belt. the easiest way is to use a 1/2 inch socket set breaker bar insert square part of bar into square hole on tension pulley mount and move in direction of arrow.once you move it far enuff you can slide blet off at least one pully.then slowly release bar putting new belt on opposite of taking off,but make sure you route the belt the proper way or you wont get the tension needed to operate

**STOP** PRIOR TO REMOVING THE BELT TAKE NOTE OF THE BELT ROUTING, CHECK FOR A DIAGRAM ON THE RADIATOR SHROUD Now to replace the belt, rotate the automatic belt tensioner counterclockwise to release belt tension. remove the belt from the auxiliary components and slowly release the tensioner. Route the new belt over the various pulleys, **see note above**, then rotate the tensioner and set the belt in the grooves. be sure the belt is seated in the grooves on all pulleys, then release slowly.

The most reliable way is to go directly to the belt manufacturer's site. In your owners manual, and near the serpentine belt there should be a routing diagram for your model that will show you the configurations(AC / no AC). also your owners manual should have a full set of specs for your specific model of vehicle. The belt routing is dependent upon the car you have.
