2009 coolant overflow cap

So this is for the reservoir right behind the radiator before the engine probably going to have to go to the dealer or get one off of a junk car by walking up to it and pulling it off I sure how you lost it because it's usually secured with a piece of plastic and hangs when you undo it and give somebody broke it

A friend of mine Old mage is out that way I just sent him some stuff not too long ago for one of his Prius I do know he said there's a few places around with these cars so it shouldn't be a humongous problem it's a round up the little cap you need In the meantime just ball up a plastic bag and stick it in there nothing really goes on in there it's not really under pressure Make sure the cooling is sitting at the plastic guides just under the filler neck and let it rip nothing's happening in there when you go flying by some place like a tow lot or whatever and you see one sitting in there popping there and pull it off and take it with you
