First thing to do would be find and fix the coolant leak, if it is coolant and not just a leak from around the back of the hood or from melting ice. Maybe you could trace the water trail back from where it looks like it's coming from to get to the plug. Does that make sense- coolant will leave an oil-like trace when it dries. Use a good dielectric grease on the boot- that may help keep the water from shorting out that plug.
