Our '94 Cavalier does not have a tension bolt, it simply needs the rightinstallation, as per the diagram on the car. After scraping off the crudwe could see the diagram.
The belt doesn't go in a 'loop' fashion, it loops around the first few thanUP to a pulley and DOWN to last pulley then across to front. .

The center pulley is the "tension" pulley you have to push it down to get the belt on. I also take the top bolt out of the alternator and loosen the bottom one so I can move it forward a little to get it on. I'm a girl and I don't have the muscle power to do it the other way. I also. :-)
The tensioner is automatic, if it fails to tension the belt enough a new tensioner and belt should be fitted, beware it in not an easy job. Dave.
undo the bottom bolt on the alternator and the top tension adjuster bolt. unbolt the ground wire going to it and pull the plug going to it. reverse all steps to put new alternator in.
if the car doesn't have an automatic tensioner than if the belt is around the alternator pully you loosen the bolt holding the alternator on and move the alternator to tighten the belt.
If the alternator is driven by a drive belt, the answer is yes. You adjust the tension by loosing the bolts on the alternator mounting brackets and sliding the alternator until the proper tension, (around 1/4" deflection at mid point of the belt) is achieved. If however it has a Serpentine Belt driving the alternator, then there is no adjustment. Tension is held by the idler pulley. If it is loose then the belt is worn out, the idler tensioner is defective, or both.
Use a 1/2 or 3/8 breaker bar to relieve tension on belt tensioner to remove and replace belt - the automatic belt tensioner is the only adjustment
To change the alternator belt an a 1985 Chevy Celebrity: 1. Loosen the adjuster bolt and the mounting bolt. 2. Move the alternator to release the belt tension and remove the belt. Reverse to reinstall a new belt.
The "serpentine" belt does not serpentine. It runs the alternator and water pump only. To change you will need to work from underneath. If you have AC remove the AC belt by loosing the AC adjuster bolt and sliding the compressor over. If you have to take the AC belt off better change it, they are cheap and you don't want to do this again for a long time. Loosen the alternator adjuster pinch bolt. Some Fireos has a adjuster screw, some don't Move the alternator to loosen belt. Remove and install new. Tension belt to recommended tension on packaging on new belt. Reinstall AC belt, use the tension instructions on the package.
It should have a spring loaded automatic tensioner, if the spring is broke replace the tensioner arm assembly
There A bolt half inch located outside a plate of the alternator on the fire wall side turn it counterclockwise either with a long wrench from on top or under the car
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
how do you reset the tension on a 1999 Chevy cavalier 2.4 litre
If it's the 2ltr diesel it has an automatic spring loaded tensioner mounted down below the alternator. A bit tight for space down there if you need to change it.
