Serpentine Belt
Under the hood should be a diagram of the belt, this is your best reference without the service manual. All you have to determine is which direction to rotate the belt tensioner, and then put the belt back on as shown in the diagram.
If it is not you can run down to your nearest auto parts store and they can print it out for you or just buy the Hayes or chilton manual on your car. It only cost a few bucks and it well helps you out later down the line if something else brakes.
Relieve Serpentine Belt Tension.
Before removing the belt, note its routing around all applicable pulleys for ease of installation.
1. Using a box end wrench on the tensioner pulley center bolt, rotate the tensioner assembly clockwise.
2. While holding the tensioner in this position, remove the alternator drive belt from one or two of the applicable pulleys.
Use a box end wrench to rotate the tensioner pulley assembly clockwise to relieve serpentine belt tension
1. Slowly release the tensioner, and remove the box end wrench from the center bolt.
2. Remove the alternator drive belt from the remaining applicable pulleys.
To install:
When installing the drive belt on the pulleys, ensure that it is properly seated in all of the pulley grooves.
1. Using the box end wrench, rotate the tensioner clockwise again, then position the drive belt on all of the pulleys.
2. Slowly release the tensioner until it eliminates all drive belt slack.
3. Inspect the tensioner indicator to be sure that the belt is properly tensioned. If the belt tension is incorrect, the belt should be replaced with a new one, or, if installing a new belt, the belt may not be the correct belt for your vehicle.
4. Then start the engine. Ensure that the drive belt works properly.
Loosen the tensioner pulley. The tensioner pulley will slide to the right. This will loosen the alternator belt. So it can be removed.
there should be a hole on the tensioner bar that fits a 3/8 ratchet. using the ratchet rotate the bar counter-clockwise(on a 2000 mustang) to loosen the belt.
The easiest way to loosen the tensioner is to use an automatic belt tensioner. This can be used on a serpentine belt which is connected to every pulley on the engine.belt.
Use a wrench and place it on the large nut. Push the wrench like you are loosening the nut. The tensioner will rotate and remove pressure from your belt.
You put a 14mm wrench or socket on the bolt and pull it towards the passenger side. That will loosen the belt. The tension is set automatically by the tensioner.
I'm guess you're asking about relieving the tension on the belt? The tensioner swivels away from the belt, thus loosening the belt. This is done by putting a wrench or socket or whatever you can fit, onto the front of the tensioner and rotating it.
The belt tensioner should have a square hole in it either 3/8" or 1/2". Use the right ratchet and pull the tensioner away from the belt. It's spring loaded. Slip the belt off once you have the tension removed.
You need to loosen the belt tensioner. There is a large bolt that needs to be loosened in the center of the tensioner pulley. Then the small vertical bolt is turned in the direction to loosen the belt. After the tensioner is loose replace the belt and retension it.
Loosen the tensioner pulley. When the tensioner pulley is loose the belt will come off. Put the new belt on and tighten the tensioner pulley.
Place a breaker bar on the lug/hole on the tensioner; then pry against the tensioner.
Loosen the belt tensioner and take the old belt off. Put the new one on and let the tensioner back in position. If you don't have a tensioner, you'll have to loosen the alternator and ac compressor adjusting bolts.
Loosen the tensioner pulley. Put the belt around the alternator pulley and the tensioner pulley. Move the tensioner pulley to the right until the belt is tight. Tighten the tensioner pulley.
