My 08 Commander 3.7 is slowly leaking coolant while not using any stored coolant in the tank. The lines fill with air over a month. If I pressurize the system and over fill it will drain into the tank like a one way check valve. Using premixed 50/50. After driving and left over night there will be 2 quarter or half dollar spot on the floor of the garage but never any more. Anyone have suggestions? Also can not find the leak location.

I'm not big on tech now days and kinda broken in the brain. What do you want me to do?
If you give me this information I will do it for you: year, model trim, engine, 4WD or not

Thank you for the help. Still don't see where to put this. Learning something new is a little hard for me but I've retained previous learned skills some how.
