    Q:
    What should you check regarding the coolant if the light doesn't go out for the 2006 Mercury Mountaineer? Posted by Customer
    A:
    If the light doesn't go out, you should check the coolant to make sure it's correctly mixed. Plain water with no antifreeze, or coolant that's mainly water, might have too low a boiling point to activate the sending unit.
