Question about 1993 Mercury Grand Marquis
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!
