My Avenger has developed a significant coolant leak. It only seems to leak though, when the engine is cool. The leak seems1 to be coming from somewhere underneath the air box. The car does not overheat. Is this likely a thermostat gasket issue? Fyi, recently changed the valve cover gasket and removed and replaced the throttle body to clean it. View attachment 20405

Well from ur pictures it appears ur engine is slightly different than our 2012 Avenger SXT PLUS with the 3.6L V6....I'm assuming, if it is an Avenger also, that it must be the 2.4L V4 version cuz of how much different it looks from ours. But I know if it's the 3.6L Avenger & ur leak seems to be coming from the air box region then I can almost promise you it's got nothing to do with the thermostat or it's gaskets as u suggested cuz on the 3.6L the thermostat is clear on the other side of the engine/engine bay so it would likely be 1 of the lines that come out & go into the heater core cuz they're fairly close to the air box area & the one line that leads out of the heater core travels right next to the air box before bein routed into the engine oil cooler (or in other words, the oil pump! but Chrysler loves to call it an engine oil cooler due to the fact they run coolant through the oil pump walls in an effort to keep the engine oil cooler by doing so) so u might check that connection & make sure it's not leaking somewhere or maybe the spring loaded hose clamp slipped off (though this is extremely unlikely as those things, or at least all of the 1's on our Avenger, are insanely tight & difficult to even loosen up let alone get completely off of the their coolant hoses) but a large range of circumstances could have happened to cause that specific hose to start leaking so I'd check there & maybe it'd just be a good idea 2do a full system flush & drain & refill with correct type & amount of coolant so you know that's not got anything to do with the leak.... Best of luck.
