Yeah, online their sold "by the dozen", so I think it's just a hole plug...there's no fluid(s) anywhere...
I'll give it to the dealer and let them figure it out.
Odd though
I found one on my driveway also. Helpful respondents directed me to an exploded view part diagram and I found a blind hole that it fit into. I don't know if it stayed put, and probably doesn't matter. Strange that it happened to drop on the driveway in the first couple of days.
This gives me the idea to gather random engine parts and place them under peoples cars to freak them out. hehehe
that would be a good prank, go pick up some used power steering hoses and a wiring harness.
We were going to pour some water with green food coloring in it under a coworkers car who refused to fix a leak and then finally fixed it a month later. We were also really thinking of pouring it under the rear of his car to really mess with his brain.
