I've ordered the belt to replace this but am wondering what caused it, and if I should do the belt tensioner while I'm in there?
I've been smelling burning rubber for the last couple of days (usually smell burning oil but that's another thread) and looking around the engine for the culprit I found this.
There is some residue on the alternator in the pic, as well as other areas along the belts path. It appears to have a string or cord that got caught on something because at the top and bottom of that damage there is a frayed end...and I found a small piece of string caught on the spindle where the cooling fan attaches.
Is this normal wear? I had to replace the alternator about 10 months ago and i've read that a failing tensioner will take out your alternator and give the serpentine belt weird damage, but as I'm new to this I am hoping for some forum feedback.
As always, I sincerely appreciate any time spent answering car questions. Love this thing dearly and want her to be around for a while.
