Sorry for delay in responding.
Did you spray the pulley with the engine running? If so you may have also sprayed the belt. It is possible the new belt could be the problem, have seen that a few times.
If making noise again spray the bolt again before starting. Also when replace the pulley did you make sure it spun freely? With some new pulleys the original washer doesn't work so well and will cause problems.
