Given they are about 9 years old I just replaced the supercharger / PS pump, accessory and oil pump belts.
The top 3 Torx screws of the oil pump cover are a PITA to remove and install. There isn't too much clearance for tools and the threads are quite long. So I made this small tool to spin them on or off once they are broken loose with the short 1/4" drive T30 bit. It is just a T30 bit pushed through a small hole drilled into wood dowel (cut broom handle).
