after they told me car is fixed I drive for 20 min and the temprature was below the middel after I park my car with few minutes the hose and the clamp explode again and all water comes out of the radiator again. I know there is pressure proplem still with the cooling system but I don't know what else I need to replace after all of the long list above.
