Some think that the factory put a spring in the lower hose to keep the water pump from sucking it shut, they did not. In the picture below you see why the factory put that spring in there. Maybe the time it takes to uncollapse that hose when vacuum filling the system matters to the factory, to me it did not. I am not rolling a new car off the assembly line every three minutes, lol.

If your lower radiator hose is collapsing at speed, you have a flow restriction somewhere, or a water pump spinning too fast.
