hi all
most cars have a timing belt rewnal interval such as 70k (some less, some above) you should check the oweners manual or even google it im sure youll find somthing on it, also on the wyning noise its sounds like a bearing gone but you need to narrow it down, from the info given it dose not sound like a gearbox problem, just try when ideling putting your foot on the clutch and see if it has any affect on it this will help to see if its the clutch bearing, if not try removing the fan belt it could be from a retaining bolt on the alternator or a spring loaded pully and see if the noise gose out of it this will help narrow it down to the bearing attached to the fan belt so try each one by hand and see which one is gone (Alternator first and so forth) if its still there its more than likly from the waterpump which would meen getting the timing belt replaced anyway, this is like open heart surgery for an engine and has to be done right so if you dont know what your doing get a pro to look at it (safest bet)
this is only a guide to trouble shooting and hope it helps
