Hello, I have a 2005 Pacifica with the 3.8L V6. Today I noticed a water or coolant leak on the driver side where the exhaust manifold goes around from the front to the back of the engine. It is actually dripping from the bottom of the exhaust manifold down onto the transmission. I looked as far down as I could see on the back of the engine and I can see a small amount of water or coolant has dripped back there too. Does anyone know what would cause this? Thanks.
