I have a 2000 Ford Mustang (Automatic/3.8L) and I have noticed a leak. It looks like it is coolant but I’m not sure where it is coming from. I don’t have any holes in any of the hoses and I don’t see any leaks coming from the bottom of car. I don’t notice anything when the car is running. It seems when my car sits for a day or two, I notice the leak.

If anyone could give me any insight on the leak (possible location, fluid?, possible fix) it would be greatly appreciated. Thank you for your time in advance.

 

That is your water pump.It might be leaking from hvac pipe (the black pipe thats circled) that go's in the water pump. Theirs a o-ring around it to seal it.

 

Agreed. That and you might want to just replace that whole pipe. It looks like it has some corrosion on it as it enters the Manifold.
