Two days before fixing the starter on my 90, my 110 started with a new noise.
300Tdi.
It seems to begin after fully warm. Most often at highway speed. Sounds like the squeaking/squealing of a lose alternator belt. But I don't think a serpentine belt can slip or squeal like that.
Or can it? The idler pulley seems to keep the correct tension.
My next thought was the accessories. I've checked idler pulley, water pump, alternator, nothing obvious. Except the idler has a little play.
I have an electric fan, so no viscus fan.
Ideas? What else to check for? How do I verify the idler is good or bad?
I'm avoiding driving it for now. Good thing I have my 90 running again.:grin
Thanks as always.
