I changed the alternator on my 99 alero an now it makes a loud sweeking niose is there a way to tighten the belt


LOOSE BELT MORE LIKELY YOU HAVE A BAD BELT TENSIONER.A BAD BELT TENSIONER WILL CAUSE BELT TO SLIP.WHEN THAT HAPPENS ALTERNATOR CANT SPIN FAST ENOUGH TO KEEP BATTERY CHARGE.AND IF YOUR WATER PUMP DONT SPIN FAST ENOUGH ENGINE WILL OVERHEAT AND YOU WILL HAVE POWER STEERING PROBLEMS ALSO HAVE DRIVE BELT TENSIONER CHECK OUT AT A GARAGE..

Short duration screech when car is started. Last longer in cold weather. Had top two belts replaced within last 24 months. apparently there are three belts.


One of the belts is loose. I would say it is the Alternator Belt.
What happens is that when you use the battery to start the car, the alternator immediately attempts to charge the battery back up once the car starts.
If the belt is loose, the belts slips some, making that horrible screech, until the battery is charged enough that the belt no longer slips, because the alternator no longer needs to make as much power, and the screech goes away.

Check to see that your alternator belt is the next one to replace, and tighten it up to specs.

Battery engine warning light came on. what is the likely problem. truck runs fine otherwise


Most likely cause is the alternator is not providing adequate voltage to keep the battery charged. It may be that the alternator belt is slipping. Try tightening the belt or spray it with some stop-slip. Other than that it could mean a short or a bad alternator. Register at www.autozone.com (it's free). Once registered you can download detailed info about your truck to help you accurately diagnose the problem.

Charging system stops charging when the throtle is snaped. accelerate slow charging normal. lights on charging normal


Indication of a bad alternator or the easiest and most inexpensive thing to check is the serpentine or v belt, it might be slipping during hard accerlation and the alternator is not keeping up. With out knowing the car or truck I have no way of telling you how to tighten the belt.

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

Squealing noise


Check and tighten your drive belts / fan belts. The noise you are most likely hearing is the belt slipping on the alternator pulley. Its worse in the morning because the starter takes more out of the battery when the engine is cold. This in turn leaves the alternator with more load to replenish charge. More load = more resistance on the pulley to turn, hence the belt slips if too loose.
