I have a pretty good sized coolant leak. I think it is from around the rear of the water pump. Coolant drips down on the left side of the oil pan and slashes back all the way to the tranny pan. All the hose connections look good. The two connections with the small "O" rings look tight. The pump is about 6.5 years old with about 40,000 miles on it. Does this seem premature? It is a Laso pump.

Thanks,
