2012 chevy sonic possible oil cooler leak. Coolant in oil. Can i flush the engine and fix the oil cooler or cut my losses.
My question is can I fix it or is it a waste of time. So we just aquired a 2012 chevy sonic with 181k on it. I noticed when i got home the oil looked newer and a bit to full. I changed the oil it came out very black instead of like the newer color i saw the dat before. I also noticed the coolant level was down, so i added more coolant. The next day the coolant was down again. I was showing someone the car and in the back was some old coilant jugs and water jugs.
