Question about 1993 Mercury Grand Marquis

1 Answer

Coolant leaking from underneath car near oil pan.

We have a coolant leak in our Grand Marquis. We see the water leaking underneath the car just past the oil pan. It appears that it is leaking out of a pan that is just past the oil pan as you are going from front to back. Also, this next pan has a plastic plug that also has coolant leaking from it. Any idea what's going on here and how to stop the leak?

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!

Coolant leak


Most likely cause would be a leaky coolant hose near the engine block. When the car is warmed up and you turn it off, open the hood and look and listen for a hissing or a stream of coolant coming from one of the coolant hoses. If you can't see the source from above, you might need to look from underneath. If you can see where it's leaking, it might be as easy to fix as a hose change. Or it might be something a little harder to fix. But you need to start by finding the source of the leak.

Why is my car losing antifreeze but there are no visible leaks, even under pressure??


Usually means you have a head gasket leaking coolant into the cylinders and the engine is burning it out the exhaust pipe. Once the leak gets bigger than what the cylinders can burn, it will show up in the engine oil.

I just bought a1995 Mercury Grand Marquis and it is low on oil and does not have coolant. So my question is, what is the best coolant and oil to use for my Mercury Grand Marquis?


Cheap until you know the condition of the motor. Top up the fluids with store brand or whatever is on sale and get the engine running. Let it warm up to operating temperature and start looking for leaks that need to be fixed. There's a reason why there's no coolant and it's not likely to be that the other guy drained it out for another car. There are a number of reasons there is no coolant, bad rad, bad water pump, bad heater core, leaking hoses, bad head gasket, warped heads. Fix this first and then most any name brand coolant is good.

Oil wise again name brands are your best choice. At least 10W30 or maybe 10W40 depending on mileage. Mileage in the 200,000 range would use 10W40 without any problems. Hope this helps.

Water was found leaking from my oil pan and car is overheating. I have a 95 Mazda MX3


Is it leaking FROM the oil pan, or dripping OFF the oil pan?

If its dripping OFF the oil pan, that leads me to beleive you have a coolant leak somewhere. Check the coolant level. Check for leaks.

Check your oil, if the oil is milky/coffee colored. Or if your coolant looks kinda nasty, you may be looking at a headgasket.

Over past 3 weeks car has used 2 gallons of coolant with no leak


It is either being burned off in the combustion chamber or leaking into the oil pan.
Check your oil level on the dipstick and note any abnormalities; way overfilled, foamy, tan colored, etc.

If nothing, have the cooling system pressure tested.

Note that GM issued a recall on these vehicles for intake manifold coolant leaks, resulting in your situation exactly. Verify the recall has been performed.

Coolant/temp Warning light


Yes, fill your reservoir and see if you have a leak there....if it is something worse, drain some oil from the oil pan and see if you have coolant or a milky look to the oil. Another thing to is your water pump may have bit the big one.

93 mercury grand marquis oil pan leak


Sometimes you can remove the engine mounts and jack the engine up high enough to remove the pan. If it is really rusty it is hard to get any type of epoxy or metal repair to stick.
