Larry:
Check the width of the belt you are using. Too narrow of a belt will
bottom out in the groove and not get sufficient loading of the sides of
the vee to drive properly.
The belt should be 9.5mm and when laid into the pulley groove should not
bottom out.
A problem with the alternator can also cause belt squeal.
On your late car it is also possible for the pressed steel water pump
pulley to fail, this will allow the belt to bottom out and not drive
properly.
Hope this helps.
