Mike, I believe that the coil spring you mentioned is more for protection; than reinforcement of the radiator hose. But I may be wrong.
Mine intially was delivered at time of purchase without a coil spring.
That is a possibility I suppose but perhaps it serves both purpose. I'll post a pic later today. Right now I have to go out and spread 5 yards of crushed rock in front of my shop, and at my age. Gads!
