Here's the stock one, the belt ten. was stretched past the max because I have a slightly bigger idler pulley from the ebay special that was in it in the past.
Here it is side by side, its oreillys brand out of a 05 Buick Rainier with 5.3L, I got the new one because the reman was $139 +25 core, and the new was $159 + 5 core so with no core it was a easy choice.
I put the pully from the ebay rewound on because the car idles low.
Here it is, idle volts are way better now, im going to grind down the rear support to made it fit but for now i just made a little heat sheild out of roof flashing.
