Yes, replace the hose. Six years is long beyond the useful life to the hose. But your leak may not be the hose- it may be that the outlet is deformed and not allowing the hose to seal properly, or the outlet solder joint on the radiator tank is leaking. If the solder joint is leaking, take the radiator to a radiator shop or the repair. Unless you are pretty good at soldering with a torch.
