coolant leaking

Hey I took my bike out for the first ride this summer in Minnesota the other day. When I got back, I noticed this white fluid leaking out of a hose on the left side of my bike. Sorry I'm not too mechanical. Can anyone tell me what this is and how easy/difficult it's going to be to fix? Thanks...

Hey brothers I just noticed two drops of coolant on the floor today and I can't figure out what it's coming from the hose or that bolt on the bottom of the engine which is second picture and should my hose be over top of that nub or is that correct on the third picture any advise would help...
