Hey guys I am having a problem. I have a coolant leak coming somewhere from the back of the engine. It leaks only when the engine is off. While it is running there is no leak at all. It isn't coming from the heads or the intake manifold from what I can tell. I see it leaking from between the transmission and engine...right where the access to the torque converter bolts are. Does this sound like a freeze plug to you? I would think a freeze plug will leak when the engine is running and when it is off. What do you guys think about this?

You sure its not the air-conditioning, or does it smell like coolant?

Turned out to be the tube that runs under the intake manifold. I forgot to put the o-rings on it.
