Hello all,
I'm New here and happy to have found you

My 95 Mercury Mystique LS V6 has been awesome since I bought it used a few years ago. But, I just drove from Halifax to Barrie Ontario and the engine was making a squeeling sort of noise and then died as soon as I parked it.
I was told that my belt (???) was wearing out at my last oil change but he didn't think it was an urgent repair.
The car has 160k on it now. Can anybody tell me if this sounds like just a belt breaking and about how much I can expect to pay for repairing it?
Thanks!
