Coolant Indicator ON-notice leak

Hi,

2 weeks ago my 1995 C220 Coolant Indiactor came ON, I check the plastic coolant tank (the level) is low. I waited for the engine (http://www.mercedesforum.com/m_45499/tm.htm#) to cool after a few hrs, then I top up with water. 4 days ago, the indicator cam ON again. I decided to check the base of the engine, where there is the plastic base, I notice slight liquid with green colour coolant. I think this confirms a small leak somewhere.

I notice the leak may not be from the radiator (http://www.mercedesforum.com/m_45499/tm.htm#) but below the engine. You notice on the photo I have remove the fan blade to get a better view of where the leak is. It look like from the hose connected below the engine. Can any one pls help me to diagnose.


Kind Regard
