I just came back from a test drive..lol changed the oil wanted to make sure that it was running ok, its the wifes car. 2004 natural aspiration, 3800, noticed before i changed the oil that it looked like it had been leaking, but i have had to put a quart in it between changes, so assumed thats what it was. Well took her down the road ran it hard, and guess what, water everywhere. I checked underneath, sure enough middle freeze plug, but has a wire going to it, its close to the sensor too, and starter and has a oring as well. It was out on the top just enough to let out alot of the antifreeze. Is this a common issue? Should just tapping it back in be ok? Any advice?
