Replace the springs and all the idler and tensioner pulleys.
Why you ask? Simple when I had mine replaced, the guy got in there and started finding pieces of plastic and the belt had some nice grooves and burn marks. What happened? Either one of the idlers or the tensioner pulley that the belt runs on seized up. We are talking bad seized up. Like blue on metal colored discoloration!
So yes, change the WP, do the UDPs, and do yourself a favor, get a rebuild kit including pullies for the timing belt, and cam gears.
