If you see the "coolant over temperature" alert on your Ford Explorer, it could be due to either the coolant being too hot or a faulty coolant temperature sensor. Avoid opening the coolant reservoir when the engine is hot, but check if the engine is emitting excessive heat. Start by using an OBD-II scan tool to check for any diagnostic trouble codes (DTCs). The most common DTC associated with this warning is P1289, which indicates a failed temperature sensor. If no codes are found, consider checking the coolant levels and looking for any obstructions in the system. Make sure the antifreeze levels are adequate before proceeding with further diagnosis.
