The fuel filter on these vehicles is attached to the underbody, in
front of the fuel tank. Note that there are no service intervals for
in-line fuel filter replacement. Only replace the filter if performance
problems or troubleshooting indicates the filter is restricted.
Fig. Location of the fuel filter. Note a threaded fitting on the inlet and a quick-connect fitting on the outlet end.
Hope this help (remember rated this post).

The Location of the oil filter depends on which engine you have in your CTS. the 3.2 engine the oil filter is located on the bottom of the engine to the left of the oil pan. It is not a screw on type filter it is a canister filter. You will have to unscrew the lid to gain access to the oil filter. On the 3.6 Engine the oil filter is also a canister filter but it is located on the top side of the engine. On the drivers side around the center of the engine cover. It will take a 15/16 socket to remove the lid.
