The 93 Acclaim has a serpentine belt. The tensioner below the alternator is what keeps the tension. If you have not tension I would replace the belt first and then check the tensioner.
Adjust the belt or replace it with a new one.
Just below alternator.
It uses a spring loaded belt tensioner I believe. The tensioner is automatically set. IF there is not enough tension, then replace the tensioner. The belt may be stretched and need replacment however.
That usually means that the belt is slipping on the alternator pulley. You should be able to check the belt tension and if there is a tensioner, you may need to replace the spring. Otherwise, just tighten the belt.
There is a tensioner bolt that is connected to the alternator. You have to screw in the bolt, which will pull the alternator out and tighten the belt.
Serpentine belt? You may have to remove to tighten alternator
The adjuster is located underneath the alternator. Three bolts are involved, the first to loosen is the main bolt that hangs the alternator to its bracket, the second is underneath the unit on the left hand side - this would be the actual locking nut. The third is down underneath yet towards the front of the alternator; it actually moves the entire alternator forward or backward thus tightening or loosening the belt. Once the belt is tight, tighten the lock nut and then the main attaching bolt. About the lock nut, it is part of the adjuster mechanism underneath the alternator; both the lock nut and adjuster bolt are difficult to see especially if you have air conditioning like I use to.
To tighten the alternator best on a 240sx, loosen the bolt on the alternator on the drivers side. Pull on the alternator away from the engine to adjust the belt. When it has no more than a quarter inch of give, tighten the bolt to finish.

depending on the style of belt, on the alternator belt there is an adjustment just below the slider holding the alternator, you just simply tighten it until belt becomes tight.
Theres a pulley tensionor, loosen the bolts to it, pull it tight and retighten bolts, but dont over tighten the belt... there should be alittle play but not much, because if its to tight, it can break, to lose and it will come off, once you tighten tensionor, it should have about a quarter of an inch of play.
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.
