Replaced belt AND tensioner....STILL rattle at Start up

[dblhelx]

As the title says....the infamous rattle noise at start up is usually a bad belt tensioner, a known defective part. Well I replaced the belt and the tensioner and still have that exact noise at cold start up. Goes away right away and only when I start in the morning or if the car has been sitting for 8+ hours after work.

Any other ideas oh Corolla gurus of the world?

Did you spin the other pulleys when you had the belt off?

[dblhelx]

Nope, didn't bother. Everything pointed towards the usual tensioner. Suggesting a different pulley is bad?

How long ago did you put it on? did you use on OEM one? and if so, which part# did you get, because that part has superseeded a few times.

Did this last weekend, used a new part from Autozone. if if the Autozone part isn't the upgraded version, it's new, and shouldn't be rattling already...no?

There is a Toyota TSB regarding this very situationl. They have redesigned the tensioner and the bulletin calls for replacing the belt too. I am suspecting that the Autozone one isn't up to factory Specifications. That is all I can really think of. Sorry, wish I had a better answer for you.
