2005 Cadillac STS engine?
How can you tell what kind of engine it has?
Like V6 or V8
My girlfriend has one and I would like to know. How can I do this?

It could have either a 3.6L V6 or the 4.6L Northstar V8. the quick and dirty way to check would be to pop the hood and count the sparkplug/COP wires.

You can also check the sticker in the glove box. This sticker has the RPO codes. You can visit your local dealership with the VIN and see if they will provide you with the build sheet information.
