They battery tray is toast. No leaks from the tank or hoses for washer fluid. But both are new. Tank replaced by PO and battery by me, although the OEM battery before did not appear to leak.

So at one time, I suspect maybe some issues. I will probably pull the battery soon anyway, time to de-leaf the car.
