Oil Change

I cannot find the Wrench Sizes that I need For my 2002 Caviler LS with EcoTec engine. Does Anyone Know? I need to know the sizes for oil plug and filter.

Oil drain plug on aluminum oil pan is a 15mm....I use a large american fractional size socket on the filter of my 2004 Ecotec engine (can't remember the size right now)....Fred

on the filter use a 1 1/4" socket you can get one for 5 bucks at the part store
