SOURCE: Coolant leaking from underneath car near oil pan.
THIS IS STRANGE, BECAUSE THE NEXT PAN BEHIND THE OIL PAN IS THE TRANSMISSION PAN. UNLESS MECURY HAS DEVELOPED SOME STRANGE SYSTEM THERE SHOULD BE NO WATER OR COOLANT ANYWHERE IN THAT LOCATION? IF THE PLASTIC PLUG IS LEAKING IT CAN BE FIXED BY REMOVING IT AND WRAPPING THE THREAD WITH TEFLON TAPE AND RE-INSERTING IT AND TIGHTEN IT. IT THE PAN ITSELF IS LEAKING, THERE ARE ONLY TWO THINGS HERE. ONE, YOU CAN RE-TIGHTEN THE BOLTS TO SEE IF THEY ARE LOOSE AND SEE IT THIS STOPS THE LEAKING. OR, IF THE LEAKING DOESN'T STOP, YOU NEED TO REPLACE THE PAN GASKET WITH A NEW ONE AND REFILL THE TRANSMISSION WITH NEW OIL. YOU MIGHT AS WELL CHANGE THE FILTER WHEN YOU HAVE THE PAN OFF, BECAUSE IT IS PROBABLY OVERDUE. I THINK YOU WILL FIND THIS LEAK IS A STICKY RED FLUID CALLED ATF OR AUTOMATIC TRANS. FLUID. THAT WILL NEED TO BE REPLACED. NEW FILTER, NEW GASKET RETORQUE THE BOLTS, IMPORTANT, DON'T WANT THAT THING FALLING OFF, NEW FLUID, YOUR BABY SHOULD PURR AND NOT WIZ ON THE FLOOR ANYMORE. NOT SURE HOW TO DO ALL THIS? BEAT FEET TO THE NEAREST PARTS STORE AND BUY OR ORDER THE CHILTON OR HAYNES MANUAL FOR 93GRAND MARQUIS AND YOU WILL HAVE PICTURES AND STORIES YOU WON'T BELIEVE! CAN'T GO WRONG! GOOD LUCK!

If u have a moderate climate, 10W-30W, if cold climate 5W-30W, do not use any heavier weight of oils.
SOURCE: 2000 grand marquis cruise control not working
Have seen this problem before. You need to look under dash at brake pedal and find a blue switch with plunger contacting pedal, disconnect connector and jump with a peice of wire and drive to see if cruise works and if it does replace deactivation switch this should get you going.
SOURCE: where are the spark plugs located on a 2000 Mercury Grand Marquis
There are eight COPs (coil-on-plugs) to remove. Using a 7mm or 9/32" socket, remove each bolt securing each COP to the intake manifold on top of the engine. Remove all eight COPs, and the spark plugs are underneath. When replacing the spark plugs, use only the proper Ford/Motorcraft plugs, even if they cost twice as much as the aftermarket ones. You will avoid further headaches this way. Hope this helps.
