Car starts every time, but it makes a rather shrill screeching noise. And it has been turning several times before starting up recently, although when I bought it a few months ago it started up on the 2nd or 3rd turn. Do I need a new starter, or is something maybe just loose? Could it be somehow connected to me having an old battery? Is a starter replacement something a moderately determined do-it-yourselfer can do without buying (another) garage full of equipment? And, if I keep using the starter that's in it as it is until it simply won't start anymore, what other damage am I risking?
