2003 AME E55 LEAKING COOLANT
I noticed a small spot of liquid in my driveway along with low coolant level indicator in my car.I filled it with coolant,only to have it run out again,and the car leaking coolant onto my driveway;this time in a much larger spot.The car so far does not run hot.There is no water pump or supercharged squeak or sound,that makes me feel it's the water pump,or any indication of busted top radiator hose.
Any idea what this might be,and how difficult and expensive a fix this might be?

Sounds like normal wear.
If the water pump is gone then you will need a new belt and tensioner. The simple reason is that coolant ruins these parts.
If the small pressure hose is leaking between the engine and coolant reservoir, just replace the hose.
You may also have a cracked fitting. Sometimes people overtighten the hose clamps and put tiny cracks in the plastic openings. Over time the crack grows and you need a replacement part. Sometimes this happens to radiators.
Check for any minor damage under the engine where a rock might hit the radiator.
Nothing to be worried about. All of these problems are easy to fix.
