my ford ran hot and it has oil mixed with gas coolant pouring out from the bottom after it ideals

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Oh boy, that's a rough situation for your Flex. When an engine runs hot and then you start seeing oil and coolant mixing – sometimes looking like a forbidden milkshake – and fluids making a hasty exit from underneath, it's a pretty clear signal that something serious has gone wrong internally. It's like the engine's internal walls have broken down, and now fluids that should never meet are having a very unwelcome party. The most common culprit for this kind of symptom, especially after an overheat, is a blown head gasket. The head gasket is the crucial seal between the engine block and the cylinder head. When it fails, it can allow coolant to get into the oil passages (hence the "water in the oil") and vice-versa. It can also cause coolant to leak externally. That "oil mixed with gas coolant" pouring out sounds like a pretty significant breach. My best advice here is to stop running the engine immediately. Driving it in this condition can cause much more severe, potentially catastrophic engine damage. This isn't a "wait and see" kind of problem; it needs to be diagnosed by a trusted mechanic as soon as possible to determine the extent of the damage and the necessary repairs.
