I have an 05 Magnum RT w a 5.7 HEMI, about 80K miles on it. It runs fine, but I just noticed that last night that it loses antifreeze slowly. Last summer I had a mechanic friend of mine change the AC compressor, and at that time he told me it was a little low on antifreeze and topped it up. I checked it last night (engine cold) and sure enough it's down about 1/2 gallon. In that time span I've probably put between 8-10K miles on it.
It doesn't leak that I can see and I can't smell it, and it's not getting into the oil cause I change the oil at 5K miles and its relatively clear, oils not milky at all. Is it burning it? Slowly leaking past the head gasket somewhere and getting into a cylinder?
I'm going to be changing the plugs soon, could u tell from the plugs if it was burning it?
