Hi
 
	Coolant is leaking from the upper radiator hose where it connects to the ???   Not the connection on the radiator, but the other end.  The part isn't named/numbered on the yamaha parts diagrams online.
 
	Anyway - how hard it is to replace this hose?  I tightened the upper clamp, but it is still leaking.
