I was heading home with the girlfriend yesterday and notice my battery light came on, then my A/C went warm and I lost my power steering and heard the most horrid squeal come from the motor and smelt burnt rubber and I knew right away what happened. The tow-truck driver put the car in the garage for me which was cool. I wouldn't have had it towed if it wasn't free (gotta love AAA)

anyway . . .
I opened the hood to find shredded belt tangled up all over the place :bang: and the tensioner pully was just dangling on the bolt. AFter picking pieces of the belt out of all the accessories, I took off the tensioner pully. The damn thing was mangled and the bearing fell into a million pieces onto the garage floor and the balls bounced all over the place. The whole thing was blue from the heat.

Has anyone had this happen? I don't know how the tensioner pully could go like that :shrug: It was making noise for about a month but I didn't realize it was the tensioner making the noises in there.
 
ive heard of it a time or two before (on foxes, which have a few years on your guys' rides).
was it just the actual pulley that took a dump, or the entire tensioner mechanism? a new pulley is about 15 bucks at the parts store, but be warned it is plastic. ive run one for about a year and it seems fine. but if you turn a lot of RPM's, i dont know that i would run one - it doesnt inspire confidence (i hate plastic anything).

if you swap the pulley, IIRC the bolt is reverse threaded.
id check real quick to make sure that each pulley spins freely, also.
im sure you know all of this - i just felt like typing. :)
good luck, John.
 
Well I fixed in in like 20 minutes, it was only the pulley, the bearing just seized. I got a new one and it looked just like the stocker and it's metal. It took all that time just to get the pieces of belt out from behind the alternator pully. The bolt isn't reversed though, I use a socket to turn it to get the belt on and it tightens it. I was just wondering if it was a common problem cuz I really would hate for that to happen on the highway or something.
 
On my truck, my a/c clutch compressor bearing locked up on me, and the belt started to smoke really bad. Idle pulley on mom's truck did the same. These things happen; I wouldn't worry too much about it.

I replaced the pulleys on both, and haven't had a problem since. My truck went an extra 30k miles & mom's has gone at least another 5k; Both without any problems.

But this is the first time I have heard of this problem on a mustang before.

John, nice work. i apologize for the bad info on the idler pulley bolt being reverse threaded (i could have sworn it was. i got rocks upstairs).

where did you get a metal one, if you dont mind my asking? when i got mine, the plastic one for 15 was the cheapest i found (checker).
