hello friend I wonder if the tensioner pulley is metal and if it profit a 2005 Aveo automatic thanks

Yes it is metal and it is specific for the make and model and engine of the vehicle. This one fits 5.3L V8 engines and possibly others, but I am sure it would not fit on an Aveo. You are best off to take your car to an auto mechanic.

Does this fit a 2004 Yukon Denali 6.0?

I used it on a 2005 Denali 6.0, so should be the same.

Does this fit a 97 Buick park Avenue ultra supercharger 3.8

No clue, but I doubt it. I bought it for an '06 Chevy Silverado pickup with a 325 V8 and it fits perfectly.
