cooling system leak 1981 goldwing 1100

I live in Minnesota where the winters get very cold. I've owned my bike for two years. A couple of weeks ago the temperature dropped to about 20 below for 3 days. Soon after that i noticed that antifreeze had pooled on top of the engine. Equal amounts of coolant on top of either side of the engine. I have the same coolant in the bike as the previous year when this problem did not occur. Would this be a cylinder leak? Or maybe a reservoir leak? Do I now have a cracked engine block? Any advise would be much appreciated.
Thanks,
Dan

Welcome to the GWOF, Dan. I would start by good old fashioned visual inspection of everything. I would doubt if you have a cracked block. More inclined to think a coolant hose or as you said maybe reservoir.

Best of luck

Along Fossil/Bill's line of thinking, I'd suspect the O-rings on the coolant tubes on top of the engine. Basically wouldn't worry about it until it warms up and then run it and see if you're losing any coolant under normal conditions.

Appreciate the response. I did much reading on this forum after making my post and as you say probably O rings or hoses. Will fire up garage heat and start from the reservoir on down!

I found a 60watt incandescent light left on under the crankcase in cold weather prevents the what I call shrinkage leaks from happening.

Well all I know is that I've had hose connections on the bike that didn't leak in the spring, summer and fall weep some coolant when it got to freezing and below. All I could assume is that the Aluminum tube had shrank a bit. The bit of warmth from the light seemed to stop that.
