I just started my bike up the first time this year and noticed coolant was leaking so I shut it off. (It was running fine for about 10 mins before the leak started) I did not have a coolant leak last year. It looks like its leaking in a few different places, water pump bolts, alternator cover bolts, and somewhere else inside. I don't see oil in the coolant. Could it simply be that the o-rings and gaskets just went bad over the winter? It was stored inside, but unheated.

Its an 04 with 12,000 miles, and I rode it maybe 1000 miles last year.

 

Water pump bolts sound like the pump gasket is leaking. As for the others, i'm not too sure. Mine is leaking a bit as well around the water pump. Gonna replace the $4 gasket and hope that solves the issue.

 

My bike had a coolant leak this spring and all I did was flush the coolant and it went away . I guess as long as its not leaking from the weep hole on the back side of the water pump the worst it could be is a new gasket
