Works well on 2003 ChevyTrailblazer 4.2L Vortec
Installation was simple. The old part was accessible for clearance. Removal time: 20 minutes on a cool engine and serpentine belt reinstallation, but your time may vary.

Easy Install
The part came in a decent box with with generic instructions, but it's a pretty easy install. The only reason I gave it 4 stars is because the pulley is plastic and the old factory one is steel. I don't think there will be any issues, but it's something to be aware of. Overall a good part and noise problem solved.
