1997 Mercury Grand Marquis 4.6 liter mileage: 48,000. When replacing the engine coolant as suggested by the owners manual at 48,000 miles, I simply drain the old coolant from the bottom plug from the radiator then add new coolant into radiator. How much coolant and how much water should I add?
have the same problem?
