Rick - I would be a little skeptical about this one. Galvanic corrosion occurs when there are dissimilar metals and an electrolyte present. The resulting potential difference (voltage difference) between the two metals causes a current flow through the electrolyte (coolant) and a degradation of the anodic metal in the couple. I don't see how the inside of the hose could be affected, as the hose can't act as an anode.
If the hoses were reinforced with a metal mesh, and the hose degraded with age, allowing access of the coolant and therefore allowing a galvanic cell to operate, then maybe.....
Anybody know if some hoses have metallic reinforcing?
Cheers,
Glen
