DIY: Subaru Forester Engine Coolant Water Container Clean&Refill

As a standard normal procedure, i was adding some front window cleaner solvent to my forester. I was lucky that i have examined my fault before running engine: I filled the wrong container. Yes, it was the engine coolant container that filled up to head. So what i have done, after some phone call with my older brother Bülent (Like anytime that i have to take a very fast and brillant answer) was removing and cleaning the coolant water container.
