Alternater my alternater is squeeking is the belt too tight or not tight enough? i just replaced the alternater

I would be checking the tension on the belt first.

so your alternater belt is loose and you need to tighten it

could be bad earth onto chassis, also check alternater belt

They are not tight enough. Find another mechanic, the first one is incompetent. There is also an anti squeal spray if you prefer that:

is the belt stretched out! or the tensioner is weak, and not holding enough pressure on drive belt. if in doubt replace the belt. there should be marks on tensioner for the belt tension. if battery and alternater are ok. then it has to be the belt, tensioner, are the battery connection clamps, clean and tight! good-day !

Either the belt is not tight enough or your airconditioning compressor is low on oil. If the low oil is the problem, you are about to have an expensive problem when the compressor fails. So: be sure the belt is tight enough. If it is, get some oil added to the compressor. It's a special type of oil called PAG oil, by the way, so be sure to get the right stuff.

hello there
it could be caused by a slipping belt that is not tight enough try tightening the belt and see if this solves the problem if not try using some belt dressing on the belts and see if this resolves the problem hope this helps you out sincerely D.Jones

if the belt is squeeking its on its last legs, change it soon before it brakes, check that its tight and not slipping if its been slipping it will still need to be changed, but as a get you home,,, put some talc powerder on the belt that shuts them up for a time

make sure the belts are tight, the alternator belt is usually the noisey one but check them all. hope this helps.

check the alternator belt tightness, alot of the problems are caused by this :)

listen for the noise with the bonnet up, think you will find its the alternator belt squeeking or maybe a tensioner :)
