When looking at the engine from the top, it is on the right side of the engine. It has a black plastic cover on it, it will take a 1" 1/4 or so socket with a long extension on it. 03-05 Cavaliers don't have a canister for the oil filter; it's more like cartage. You can not change it from underneath; it has to be done from the top. I do the oil changes on mine.
