Hello all. I’ll freely admit this question is more academic in nature than a pressing maintenance concern, but I’m too curious for my own good. I drive a 2009 Toyota RAV4 Sport. A couple days ago, I had the misfortune of hitting a deer out in rural Kansas (though I suppose the deer was less fortunate than I was). While assessing the driveability of my newly-rearranged front end, I noticed a cracked plastic container dangling down under the car (circled in the attached photo. figuring out what it did or held seemed kind of important, but I just couldn’t make sense of it. Here’s what I know about it:
-It has a single hole, roughly quarter sized, at the top.
-It looks to hold about a quart, but was dry on the inside.
-It would have originally been behind the driver’s side headlight, or near there.
-It is not a coolant overflow, wiper fluid, or brake fluid reservoir.
I’ve looked at engine diagrams online, with no luck.
