I recently change my serpentine belt and theres noise when starting up the car and acceleration, the noise goes away after running the car for like 30 min straight but after turning the car off comes back when you turn back on

There was no noise before i just decided to change it because i had the car for 3 yrs i hadn't change it before

What can cuase that noise the belt or did i not install it right?
how can i fix it?

Check the belt and check the belt tensioner is in the normal margins.

Might need to relax the belt, pull on the belt tensioner like you would to change the belt, maybe give the belt a little turn if you can, see if the new position sits better.

I tried it but no luck the noise is still there i took to a mechanic he said the tensioner need to get replace but i feel like noise comes from the power steering pulley, i dont feel to 100% positive about switching the tensioner

Just curious did you buy OEM or aftermarket belt?

Whine might be because of a bad tensioner. Especially if you have no tension in the tensioner and it's all the way over.

Where is the triangle (arrow) in relation to the short and tall rectangles on the tensioner?

This^ Sounds like the tensioner can't handle the tension from the new belt (it's not stretched like the old one).

It was aftermarket from amazon i chaged it back to my old oem belt and the sound went away the car running again good like new

That's the problem. Get a new oem belt. Sometimes after market ones are no good.
