Not that hard to change either.

Need an adjustable wrench for the O2's and for the tensioner you need some sockets (metric). Other than that... pretty straight forward.

The O2's have one wire connectors.

The tensioner is held on by 2 bolds. Just have to get past the belt.

You can get the tool to change the oxygen sensors from autozone for like $12 or something like then then return it when you're done and get your money back.

For the O2's, you can use either a 7/8" open ended wrench, and adjustable wrench or a O2 Sensor Socket as mentioned above from Autozone. You can rent it for $12 or so or you can buy one for like $10. I went ahead and bought one for future O2 changes and I am glad I did...I needed it when I did headers and have changed them again since then.

For the tensioner, you will need a 13mm socket for the center bolt on the pulley. Turn it CLOCKWISE to release tension on the belt. Remove the belt. Then, there are two bolts the hold the pulley to the accessory bracket. Remove those and the tensioner will come off. Installation is reversal of removal.
