1998 Grand Marquis LS
173,00 kilometers
4.6 litre



As previously stated when I accelerate from standing or while the car is in motion i receive a tone and the temp guage goes from norm to all bars indicated(high) then back to norm. I was wondering if the fail safe cooling system was getting a false signal as all coolant levels are perfect. If so what sensor controls this and would replacing it solve the problem
