Coolant overflow?

Yep. And in Honda's brilliance, they made it impossible to see the actual level of the coolant in it. I'd suggest moving it it elsewhere in the cabin. I did, because my K20A swap's belt ate right through it, but even for a stock engine, I think it's something that should be fixed if you can/want to.
