Hello Kia Rio driver, my sonman got a new Kia Rio, now there are 400 kilometers on it and we wanted to refill the windscreen wiper liquid. I noticed a screw opening on the engine block. It looks like a screw would be missing. In any case there is a thread in it. Maybe the man on the assembly line was not in shape and did not tighten the screw properly? And the screw was lost by vibration? Or that’s what it belongs to? I would like to save my way to the workshop. Please see photo, red circle, there is the hole. It is left next to the oil measuring rod. Model 1.2 Gasoline Thanks Greeting from Richard
