Replace Belt tensioner 2003 CTS



Hi ALL.

Need advice. Is there any trick to changing the serpetine belt
tensioner on a 2003 cadillac CTS 3.2L. Is it easier just to replace
the pulley and bearing or should I change the entire tensioner
assembly. It looks relattively easy but I wanted to know if there are
any hidden difficulties in the procedure.
Thanks
