Belt loose to altenator - 1995 Buick Riviera

Your battery is low/dead. Charge or replace the battery. Maybe your altenator has died or the belt is loose on it and has caused your battery to die. Also possible that the battery's cables are loose and do not allow the altenator to charge it.

Tighten your serpentine belt.

you will need a 14 mm wrench a flat head screw driver 3/8 ractchet 12 mm socket short 6 inch and 1 inch extension on the front of the motor is the altenator there is a tensioner on it losen the two bolts on the front of the altenator then with th 12 mm socket turn the tensioner bolt it is on the right side of the altenator you will be looking directly down on it once the belt is loose enough remove then for the power steering pump belt jack car up remove passenger side wheel there you will see a dust cover remove it after its removed you will see the crankshaft pulley to your left there is the pump losen the rear bolt on the pump and then the front one should also have tensioner like the altenator asemble back together in reverse order after you make the intial tension on belt run for about 30 sec to one minute recheck tension.

When you hear this scream, it is caused by the altenator working. The belt is loose. If you have a serpentine belt then the belt tensioner is weak. If the altenator has it's own belt , then there is an adjustment bolt or pulley to tighten the belt.

disconnect the negative battery. remove the belt by rotate the tensioner roller clockwise. from the left car side u will see three hexagon screw 13mm under the altenator. loose out the screw and remove the altenator. before that unplug the two wire behind the altenator.tq

could be a votlage regulator problem. or altenator check for loose belt at altenator as well.

Hi the altenator belt? if it keeps snapping then your altenator is rather starting to seize up or its not fitted correctly, normally if its squeking its to loose.

Spin the altenator by hand and see what it sounds like, if its hard to turn or noisey that the fault.

hope this helps.

This sounds like the altenator belt is loose. When the altenator is under a load the magnetic field causes the altenator to require more fource to rotate. At higher engine rpms the belt can be slipping on the altenator pulley. There is one other possibility I can think of and that would be that the voltage regulator is faulty and and causing an overvoltage at higher engine speeds and therfore opening up the field circuit to prevent the altenator from over charging the battery this is a safety function of the regulator. I would check the belt first.

Your car has a spring loaded belt tensioner. If the belt is loose it is either routed wrong or the tensioner is bad.

Since the Altenator is run off a serpentine belt with an auto tensioner, this may not be the issue, although an old, stretched out belt could be the issue. If it's the original battery it may need changed or the altenator may be failing. Both of these can be tested for free at a local parts store, like Autozone, and I think they can do it while still on the vehicle.
