I have a 1996 Cougar XR7 that was leaking, and it turned out it was the intake manifold. Was leaking in front of the passenger side on the back. New one was 480.00. Dang car has always had a leak somewhere since it was bought new.
Radiator or hoses. Possible water pump
from your overflow valve
Knowing the YEAR would help answer your question a little better. Check these things : Water pump, INTAKE MANIFOLD GASKET, And there could be a heater hose fitting screewed into the front left corner of the intake that could be leaking. That's you standing in front of the engine looking at it. There is also a Freeze plug that is hidden on the left front side of the timing cover that could be leaking.
AnswerCheck the water pump. If the water pump bearing is worn out there will be a streak of antifreeze leaking from the bottom of the input shaft.Another prime area for coolant leaks is the intake manifold gaskets. The original gaskets fail at the front corners where the intake manifold meets the heads.

On a 2001 Mercury Cougar : The radiator is located in the engine compartment , at the front of the vehicle
front of engine at top on right side facing engine
Rear main engine seal or front transmission seals
Into the engine's radiator at the front of the engine compartment ; see the link below to a video tutorial .
If the fluid is GREEN in color and you mean near the passenger side front tire it sounds like it could be engine coolant ( usually a 50 / 50 mix of antifreeze and distilled water )
If oil is leaking from the riverside of a 1998 Honda Accord the vehicle may be experiencing a front seal leak. The main front seal is located on the crankshaft of the engine.
