Sounds like welsh plugs to me... but without knowing what the car is makes it hard.
if it leaks on left side of engine at hose,could be a bad water pump! on 3.1 engine. if pump is bad it will leak out of releif hole on bottom of pump!
it is a big possibility it is leaking from your water pump. i have a 2001 intrigue 3.5l twin cam v6 leaking from the waterpump, and am currently replacing it as i type this.
If that water is engine coolant, the heater core is leaking.
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.
Without seeing or pressure testing the system my most educated guess would be that the intake manifold is leaking.
It could be a freeze plug on the side of the engine block by the motor mount.
A leak from any water hose or the water pump, or even a freeze plug may be dripping down the side of the engine, making it appear it is a leak from under the engine. You need to get under the vrhicle to find exactly where the coolant is leaking from.
it might be the intake gasket
Heater hoses? freez plugs
If you hold the fan,with the engine NOT running, and try to move it side to side and there is not any play in it and it is not leaking, then you can assume that it is good. If it is making noise then it is defective.
On a RWD vehicle the engine is mounted front to rear. Sitting in the driver's seat, the left side of the engine is on the left side of the car. On a FWD vehicle the engine is mounted sideways. Standing looking at the side of the engine where the transmission is connected, to your left is the left side of the engine. Normally the transmission is mounted on the driver's side of the vehicle, so the left side of the engine would be the side closest to the radiator.On a RWD vehicle the engine is mounted front to rear.
