Serpentine Belt Wear

Serpentine Belt Wear
So I just purchased this 2005 S Convertible. It only has 62,000 miles on it but it needs some TLC. The serpentine belt was cracked and worn on the back side so I decided to replace it today. The install went weird, the tensioner when flexed back would not let me lock it into position. The metal piece with the holes is completely loose in side the spring, so I had the wife hold the bar while removing and installing the new belt. After installing the new belt I could smell it burning up as it began to wear on the back side just as the old one was worn, on the inside towards the engine. The tensioner does not seem loose, is not rattling, but I am thinking that that metal piece with the holes should be attached. All the pulleys spin freely without play. So should I replace the tensioner? Obviously something is off here.

check the crank pulley. Start it up and see if the face of the crank pulley is turning but not the belt grooves. This is a very common failure and would smell like burning rubber.
We only use the ATI damper when we replace them.

The tensioner was definitely bad, pulled it off today the whole thing fell apart after I unbolted it. Now I put the new tensioner with new belt and released tension. The belt is too loose, is flaps a little and I’m getting squeal. It’s definitely routed correctly, any ideas on why it is loose. Oh and I double checked the belt model and actually went and purchased a second. Both loose.

Also did you replace the idler pulley? When you replace it there are two holes it will fit in. you want it in the upper forward hole. Also does the the super charger have an upgraded pulley on it if so the belt the part store will give you will be wrong. If your talking O'Reilly they seem to have the wrong belt on file.
I copied this list from out motoring.
gates: #060406 =1050mm = stock Cooper belt
gates: #060547 =1404mm = stock Cooper S belt
gates: #060539 = 1385mm = ok for stock OR w/ 15% pulley or 17% pulley
gates: #060535 = 1379mm = best w/ 15% (and with either the 0% or 2% crank pulley)
O'Reilly can get you the right belt just add a k to the beginning of the gates part number. It will still be a gates belt they just have there own part number system.

If you don't have the upgraded pulley I cant recommended it enough. I had to replace my supper charger and splurged a little while ordering it and man I cant seem to wipe this dang grin off of my face. The little extra power is nice and really makes the car zip.
