The neck where the top hose isn't broken, but sometimes the top hose will come off under the pressure when I'm driving and coolant will leak come out. Will replacing the top hose and the clamp prevent this? I have seen threads about reinforcing the neck so it wont break incase the clamp is overtightened.
