How do you bleed the cooling system on a 2001 Mercury Grand Marquis?

Tha same as any other car. Google, "How to bleed brakes" What I do is to elevate the cars front end so as to make the radiator neck the highest point on the vehicle, then start the car with the rad cap off and allow to idle and continue adding coolant over the next 20-30 minutes. This allows the system to cycle the thermostat and bleeds the air thru the open radiator which is elevated.
