sp today I went out for a couple of hours.  nothing broke and the car did not overheat !!

but I noticed that I am getting a loud screeching sound which sounds like its coming from the front end.  it happens like clock-work at 3500 in any gear, and gets louder about 3500.  below 3500 no screeching.  sounds almost like a slipping belt.  anybody have any ideas?  thanks

 
belt was my first thought
Yup - belt tension or mis-alignment ?  Interesting only at that speed.  I had similar problem & found that a smear of talcum powder on the inside of the belt solved it but you'll possibly need to repeat occasionally as it wears off.  Rub the powder on all the exposed surfaces of the belt between each pulley.

Hope it's that easy.
