Hello all! Short time listener, first time caller. I am here today seeking help for my 2007 G6 GT, which I have affectionately named the "Hydra:" For when one mechanical problem is solved, two more take its place.
For a while now, my heater hasn't been working well/at all until the engine reached temperatures over 225°. Even then, it didn't produce much heat. I had read some posts on here, and added more coolant (prediluted) to the cold fill line. (Note, it had been low a few times in the past few weeks) I then took it for a drive, and it maintained slightly lower than normal operating temperature the whole drive. I parked, and let it set for the night. When I went outside this morning, there was a massive puddle of coolant underneath the car. It is apparent that there is a leak, but I have no idea where to look for it. What do you fellows recommend I do?
Symptoms: Overheating, large coolant leak, nonfunctional heater, and lower MPG.
Action taken: I do not have access to many tools, or even a jack, so I have not done much to it. Oil pressure sensor has been replaced recently, if that's related at all. Coolant has been added to the cold fill line before starting the car at all. Under the hood, my untrained eyes couldn't see anything leaks (looking from the top). Coolant cap is on tight, and oil level is normal.
Any help is appreciated, and I will try and provide as much additional information as I can.
