The point of the weep hole is to let coolant drip out if the seal goes bad. It shows you externally that there's a problem with an internal part. I've seen some misguided people seal the weep hole up with RTV or similar "to stop the leak", but it's obviously not a fix for the actual problem (the bad seal). The seal on the 500's water pump can be replaced, but I believe others have said that on the 250 you just need to get a new one.
