Hi, all.

While checking the oil over the weekend, I noticed and odd "clean" spot on the underside of the hood. Further inspection revealed that the rubber coolant line (?) is rubbing on the hood. It's rubbed the paint off and has worn a flat spot on the rubber hose.

So, firstly, be sure to check that hose to ensure it's not wearing prematurely. With the warmer months coming up, it stands to reason that the coolant lines will be under more stress than in the winter, so I'd hate to see anyone stranded out on the trails with a ruptured line.

Secondly, what can I do to prevent this from continuing? I did "push" gently on the hose path but don't want to kink any of the hard lines. Would a sleeve over that part of the hose make sense? I don't love the idea of it rubbing at all, as I'd be worried about corrosion on the hood underside.
