Radiator Hose Springs - Yes or No ?

I've said this a few times on these forums. The only reason that spring is in usually the bottom hose was for the fast vacuum fill on the assembly line at the factory. THE ONLY REASON! Usually there is something wrong in the cooling system if your hoses suck shut. I've never used a high volume or pressure pump, so I would suppose that could have some bearing on the situation. I worked in a Goodyear plant, and I remember the hoses that went to the car plant would have the spring in it but the same exact hose that went to the parts store did not have the spring. There was a dedicated job that the operator sat at a machine that coiled the springs, all different sizes, stainless, brass and galvanized wire. I actually asked an engineer one time about the spring and this is what he told me.
