Problem w/PRW radiator

[Jvan]

I have a serious problem w/PRW radiator that was installed years ago. All of a sudden I lost all of my fluid in the radiator. Luckily I had just pulled into my driveway. Upon inspection the lower radiator hose is not connected to the radiator; there is no metal tube on the radiator. The entire lower hose is just resting on the radiator w/clamp still on the hose. Help. Has this been a problem w/PRW aluminum radiators? It's been so many years that I'm sure any original warranty is no longer in affect.
