Default Shredded Serpentine Belt

Hello out there, I was enjoying a beautiful day out here in the SF Bay Area with the top down when all of a sudden I feel a loss of power steering followed by a battery not charging light. I pulled over & could see parts of the serpentine belt shredded. Luckily I was a block away from an Indy shop & caught him b4 closing. He will check it out for me in the morning. 2010 5.0 XKR on water pump #3. Although this time it didn’t seem like the water pump. Could be an alignment issue if the pullys from the last pump swap or who the heck knows. I’ll update you as I find out.
Cheers

If it shredded, the belt was on its way out, an idler pulley seized, or an ancillary pulley did it. Since there is no belt, turning all of the pulleys should reveal something. At least it was a nice day! It's worse when the weather is against you.

The belt was replaced about 5k miles ago during the last water pump swap so I’m figuring it’s a pully that seized.
Could be worst, I’ll update you soon.

I'd lay money they tore the belt some putting it on. BTDT on my truck and it flew apart in a snow storm last month. I just nicked the edge and it eventually started pealing ribs off.

In my old X100 same symptoms in my case the belt tensioner failed, does the 150 have one of these?

£50/$60 fix plus the belt

So far I’ve been told the tensioner failed but there’s also some oil leaking in the area that they are trying to figure out. The tensioner is 1-2 days wait so don’t know if they can figure out the oil leak until the tensioner is installed. I’m going to stop at the shop in a few hours & have a look myself.

Wow a 2-3 day wait in San Fran are you buying OEM from a dealer?

I live in a rural part of England and had a tensioner pattern part fitted purchased from a local motor factors, worked fine for 50k miles, the belt for my X100 was a Dayco IIRC, but always keep a spare for any car I've owned for the last 20yrs.

My mechanic had to compress the tensioner with scissor jack and secure with the largest cable tie he could find, fitted and he cut the cable tie and it sprung into place All in all took him 30 mins to fit...and that was with the bumper in-situ.

It’s pretty hilarious that it takes that long. I haven’t come across a part I needed on the two XKR’s I’ve owned that has been in stock. Usually it’s 24hrs. Not sure why 2-3 days this time. I briefly looked online today & couldn’t find anything that would be much quicker. At this point i’m more concerned what the oil leak is, seems like it’s engine oil but won’t know till a belt is back on & everything is operational on the pulley/belt side of things.

Reminds me of the movie U Turn. Billy Bob T told Sean Penn it was gonna be a couple of weeks for a waterpump for a Mustang. I think Sean P had sex with Jennifer Lopez. You sir! Are in luck!
