Coolant leak...what could this be a sign of?

The engine is running fine. I don't hear any knocking or any strange noises and the car is idling okay. I filled up the coolant about 2 weeks ago and its a little over low. What could this be a sign of?

Thanks

seeping water pump weep hole could be, one of many things could be causing this! need more info! year motor miles etc...

its a 1999 Camry Le v6 with about 115,000 miles on it

I think it has a slow oil leak as well so I am a little nervous. I havent had any misfires or anything so I am praying its something that wont break my bank.

Keep the oil and coolant topped off. Put a clean sheet of cardboard under the engine and watch for any stains that appear. Note the location, color, and texture. Watch for anything out of the ordinary coming out the tailpipe such as white vapor, bluish smoke, etc. When something reveals itself come back here.

do you know any sites that show where the water pump is exactly in a 1999 Toyota Camry?
