Yeah, what he said.bullzeyet said:I've had a coolant "seep" from the w-pump hole of my Gold Wing....after I've ridden the bike in the very cold weather (talking 17-20 deg temps here). Put the bike back into garage...got "some" seepage. I thought like you...seal problem. BUT, it was just the "extreme temps" that caused this problem. I keep checking the seep hole(over many days/weeks) and never had it again...till another very cold day ride. :shock: :? But as springtime came around was worried about this but the "seepage" stopped and over the high temp summer months never had a problem.
I had a KLR650 do that, only dripped in cold weather. It dripped when cold about the last year I had the bike. I added a little distilled water to the overflow tank, but not enough to raise the freezing point too much. I sold the bike when it had 81,000 miles and never did change the pump seal.
