I have a slow ( but noticeable ) antifreeze leak. Its coming from under the car, right before the cat-converter dripping off some hoses. What in that area could be leaking antifreeze ? And only the car is running

 

Are you sure it isn't the condensate from the A/C system?

 

bout 95% positive its not, its green, and i only ran the ac for like 5 seconds.

 

The only part of the coolant system in the back of the engine would be the cross-over pipe at the back of the heads. That and the head gaskets. Then there's the hoses/connections at the firewall for the heater. And the heater core inside the airbox, with a drain hole on the bottom of the box in case it leaks.

 

Well, i changed to a 160* Thermostat a week or so ago, and got a little antifreeze everywhere, but not back where its leaking? Unless its dribbled back there and still ther after a week ?
