Re : Serpentine belt Noise

I have a Waja Campro 2006 Model. I changed my Serpentine Belt at 100k. When the air cond compressor starts, the belt makes a lot of noise when idling. I have just changed it again (Bando) and the noise is still there. I think it has to do regarding the pre-tensioner thing.

One mechanic used a lot of greese on it, the noise stopped for only 1 day, then it became noisy again. This is just a temporary solution.

Does anyone have any advise. Does it have to go with the belt alignment?

Before I changed the belt, totally no noise. After I changed, the noise started. But when add greese to the belt, the noise goes off. So my conclusion is the belt.

But if it's the tensioner, the how can the greese on the belt reduce this noise. And when the compressor turns off, there is no noise..... or very minimal.

So the only solution now is to change the tensioner.

Appreciate your advise. Now I understand the story behind the squeele!
