Replace 2000 Chevy Impala Serpentine Belt

Chevrolet Impala Picture

Having trouble replacing the serpentine belt on my 2000 Chevrolet Impala 3.4L. I’ve got the right belt, I understand the whole tensioner thing, but the belt seems too big (though it’s the same size as the one that came off.

Ok, you most likely have it routed incorrectly, which is why it there is excess belt.

Ok. I haven’t found a diagram that EXACTLY matches my car, but it really seems obvious which way it should go.

That’s the perfect diagram, and I do indeed have it routed correctly. But my tensioner is bottomed out as far as it can go, rendering it ineffective. I felt like I had the wrong belt, but I went back to the store and they crosschecked numbers and confirmed it was correct.

You could have a bad tensioner as well.

Ok, I’ll try that. Thank you very much for your assistance.

Your welcome. Glad to help.
