I know it is coming from the gasket of the big black reservoir thingy next to the oil filter, but i am a newbie at this and have know idea what the heck that is... Any help???

 

Rocky; I had a coolant leakage two years ago and it came from one of the black plastic tanks (radiator has two attached, one each side); Chrysler dealer wanted to charge me about $900 USD for new radiator plus labor !!!! decided to take to a radiator shop...it cost me about $100 USD to "re-seal" the leakage radiator, while chatting with the shop owner he told me a new radiator was not needed, they took off the leaking black plastic tank and replaced with a new one...and working perfectly so far. He could have sold me a brand new one but he was very honest and upfront. Also I was told it is very common leakage from this specific point in Town & Country specially when maintenance manual states coolant change every 100,000 miles or so...the coolant just gets too old and begins corroding the radiator, specially on the side plastic tanks. Will try to attach images where I've got the problem...hope it helps....just can't attach images...can you advise your email ?

 

It's a oil cooler...some have it, some don't.
