Why did my upper radiator hose burst?
The most common cause for radiator hose collapse is a vacuum issue caused by a faulty radiator cap. Another common problem is clogging of the smaller radiator runoff hose, which leads to the coolant tank. As the engine cools, if fluid cannot return to the tank, this will also cause a vacuum.
Can I drive with a busted radiator hose?
