Serpetine Belt tensioner. on 1998 Chevrolet Monte Carlo

Noticed that the Belt slips a bit to the right on the tensioner itself once the engine is turned on. Assuming that it is aligning itself automatically... In addition, noticed that the pulley surface is smooth...Is that normal? Greatly appreciate any info....

This sounds normal. The belt will move side to side a bit as the engine is running, and the pulley is normally smooth. Are you having problems with the belt or just observing?
You're very welcome!
Thats what i thought. No issues with the belt so far ;). Thanks much for taking the time to respond.

It could also be if your power steering was leaking it could have been falling on the Belt.
