So, I'm finally at a loss with my damn alternator belt. I've tightened it over and over again. I've replace it twice and yet squealing still happens. Is there a tensioner that will go bad for the alternator belt? I know I'm loosening and tightening it properly but over time it just keeps squealing. When I'm at idle it does this stupid little repeated chirping. When A/C is on, it definitely keeps squealing as well.

Any insight guys? Annoyed with belts...

 

Ha ha...I got the same problem!!!!

I haven't been able to figure it out either so I just deal with it. I'm hoping to do the timing belt and accessory belts soon so I will see if anything changes.

 

Maby the bearing in your alternator is chirping.

 

^ does that mean the altenator is going bad??? not sure what you mean by that.

 

I know for sure it's the belt though...could the bearing be causing the the belt to become loose? The only reason I ask is because I don't want to buy the alternator to just be in the same spot

 

Have you checked the grooves of the pulley and the grooved side of the belt to ensure they are both free of grease, oil and contaminates? The issue could be that there is oil in the grooves that is causing the belt to slip and is giving the illusion of being loose. Just a thought.

 

I used to have this all the time , couldnt fix it . Tried Oem belt and all other kinds . Then i used a Gates belt and all the noises went away

 

Mine only does it when its cold, once it warms up it quiets down. But if I turn the A/C on even the car is warm it makes the noises.

 

I have. I've even taken brake cleaner to a rag and wiped down all of the pulleys.

That's how mine is. However, I do think the bearing may be bad on mine as well. I may just replace all of it.

Good thing I saved the one from my friends car.

what would cause a bearing to go bad because I didn't have a problem until I had all the belts changed last??

 

If I'm not mistaken if the belt has been tensioned too much or too loose the spinning of the belts will mess up the bearing because it's not on there properly

 

Subscribed, I'm having the same problem. Squeals when I start it until I rev the engine a couple times then it's good to go. I've replaced the water pump a couple times, the belts.... nothings worked

 

Seems to be a semi common issue. I just tighten mine up about every 6 months or so when its starts to squeal then im good for another 6 months.

 

take it for what it's worth...
My belt used to sqeak alot in damp mornings.
I put a small dab of bicycle chain grease(puty like, white stuff) on the under-side of the belt(the side that comes in contact with the pulley) and it barely ever sqeaks anymore.
