dont say how long it takes to overheat. try replacing thermostat,often when stuck close one hose will be cooler than the otherand check the timing,if this is out it will cause symptom. do you have the shroud around the fan still.it assists in drawing heat off radiator.other question is of course:is the temp gauge correct,see if your local garage can run their temp gun over rad etc to see what is hot and how much.or you may be able to hire one

Check the antifreeze for oil, pull your dipstick out, see if antifreeze is in oil or smells sweet or over full, sounds like you may of a bad head gasket. You can also check this by having a compression test done on the cylinders.

The Grand Marquis's have a know problem that causing overheating. The intake manifold cracks around the water inlet tubes on the intake manifold causing it to loose anti-freeze which in turn causes overheating. Mercury has a beefed up replacement intake manifold that cures the problem. It was a subject of an unannounced recall but they would replace it unless the problem occurs. The recall was for 7 years which the 1999 model wouldn't qualify for now. It happened to me and cost about $450.00 (parts and labor) to fix it. I used a local repair shop to do the work. If, after the engine is hot, you hear water/steam coming from the top of the manifold, you have the problem

This could be a broken head gasket, cracked head or block.
Pull the thermostat back out and you should be able to see water flow through the radiator. Make sure the water pump is working.
Were does the antifreeze leak from?
