Part came in handy in a pinch, it was just difficult to get to the location but that’s not the item’s fault.

This is the exact part I needed for my ‘07 Colorado 3.7l. Shipped earlier than estimated. I will order parts like this again. After all, I DO have an ‘07 Colorado!

2nd one I bought, it looks like an issue in the mold. It has a stress point where it cracks. There’s no way Gm doesn’t know about it. But they keep making the same part the same way. Typical GM.
