## Questions & Answers

**Q: hello friend I wonder if the tensioner pulley is metal and if it profit a 2005 Aveo automatic thanks**
A: 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.

**Q: Does this fit a 2004 Yukon Denali 6.0?**
A: I used it on a 2005 Denali 6.0, so should be the same.

**Q: Does this fit a 97 Buick park Avenue ultra supercharger 3.8**
A: No clue, but I doubt it.   I bought it for an '06 Chevy Silverado pickup with a  325 V8 and it fits perfectly.

**Q: Will this fit a 03 Chevrolet avalanche 1500 z66**
A: Yes fits   4.8  and 5.3 engines
