Hi everyone. This tale may sound basic to some you but it happened to me.
I own a 2003 WRX Impreza. Recently the top radiator hose had a hole open on its side from friction and heat caused by the bar that the holds the hood up. The bar gets all the heat from the radiator. This hose has a protector (which it is not as long as the hose). In my car's case, the protector slid to the right and left the hose unprotected from this friction. I am very surprised such a terrible design on this magnificent car. Just an FYI, check your hose!
