Water in the radiator cap 206

friends, cover the radiator, open the cover, close the cover, like a rubber, it breaks with the biscuit that day, I took the hood a lot of water was flowing from the cover, what should I do from the water is doing it in reducing the oil.

if you want to change the cover

The radiator door has a problem, my brother zero is 25 TL. But if the water tank is very dirty and dirty, I recommend you to change it in a figure like 65 TL.
