Oil Drain Plug Size / replacement

[Saturn9]

I knew it was just a matter of time before the torx fitting would strip in the oil drain plug.

finding the correct size was a bit of work and autozone could not find it in their computer. Huh?

I hope this saves someone time and effort if they have to do so as well.

I just went to my local GM dealer with VIN and bought a replacement. It's that easy. And I bought two oil drain plugs.

So the oil plug thread size is 14mm X 1.5mm? Being spoiled with our American system of measurement and forced to add metric tools because American industry refused to switch over to the metric system years ago, its sometimes difficult to visually size up metric fasteners. I notice 1.5mm as a popular(?) thread in several shank diameters.
