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 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 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

Can't tell much from that photo, might need to get underneath it to verify. Also, you need to tidy up that engine....with a clean engine you can see any leaks much easier...

The wet patch areas are beneath the spring hose. I think the leak from beneath or from that hose. Can I open the plastic base for me to take a better view from under the car? How do I open that plastic base?

Kind Regards

Thanks.

I have taken a few more photos of the water pump, left & right side of Radiator. Which hose would be the culprit?

Kind Regards
