Are you sure you put the belt on correctly?
yes had it done at a service center
Have the service center remove the belt and check all the belt driven accessories for free movement. You may have a belt drive item that starting to fail or even the possibility of a faulty new part!
my real question is should the tensioner be moving back and for while running or be stationary?
ive had the same problem and cant really find out why this pulley gives like it does. i have also had to replace the pulley to the right of the alternator due to a worn or broken bearing.
