My car need a lot of work on the maintenance. So quick question when I replace my serpentine belt should I replace the whole belt tensioner assembly or just the tensioner belt pulley?

Just the belt. It's super easy to do. The tensioner isn't a wear item.

Not so fast....the tensioner pully can make similar (but usually less sever) clicking noise as does TCT (although they are nothing alike mechanically). But this is a very easy fix labor wise, so if it isn't broke, you can fix it seperately if it ever gives you problems. Mine went at 68K miles. I'd just replace the belt, some folks prefer to do these kind of maintenance items in groups, which would dictate the tensioner pully & idler pully as well.
