The composite (plastic) intake manifold may crack near the thermostat housing and cause a coolant leak. Ford released an updated manifold that was reinforced to prevent a recurrence. No recall was issued for this problem but Ford did extend the warranty to seven years on some models from the date of purchase.

1997 Mercury Grand Marquis Problems
The heater hose outlet may leak coolant at the back of the intake manifold. Sometimes this is misdiagnosed as a leaking intake manifold gasket because it resembles a leaking manifold.
The EGR valve position (EVP) sensor can fail on this vehicle. The EVP sensor measures the EGR valve position and transmits the date to the engine control computer. If it fails, drivability and fuel economy can suffer, the Check Engine Light will commonly illuminate.
An oil leak may develop from the the right side head gasket. Oil from this type of leak will commonly drip onto the starter. Our technician tell us an updated head gasket is available to correct this concern.
Certain police, fleet, and natural gas models may experience lower ball joint wear, requiring replacement in the front. This was a safety recall.

1997 Mercury Grand Marquis Reviews
Have had my 1997 Grand Marquis for over 6 years....now has 220,000 miles on it..does not use oil, run great and averages 25-27 mpg on a trip with exception of mountains....then it will average about 23 mpg..does not like 87 octane and yes, the plastic manifold cracked and set me back $1100...and of course, Ford, would not repair it...seems it should have cracked 6 months earlier...after that, I have loved the car...one of the best I have ever had...and I own two Toyotas....they are great, but watch out under that pretty exterior, because they are rust buckets....plan on grabbing another Marquis when this down for good....I think the 2006 isn't so hot, but the 97 definitely is...........
my wife and I bought our Jade Green/tan leather Grand Marquis LS with 54,000 miles on it in about 2002. We now have close to 210,00 miles on it. Just about everything works on it and the trunk is clean as new. The only thing that has worn out is the driver's armrest. If I get time I can take the pin out that holds it in place and flip it over and you would not know there is a problem. The engine and transmission are great and I have had only one problem that could have cost over a thousand dollars but a friend and I spent almost a whole week dropping the entire dash board to get to the air plenum and change the switch that opens and closes the heating and cooling vents.
I would highly recommend this car and if I can find a nice one with under 100,000 miles, I would buy it. There is a nice one at the Gurley Leep Southside Ford store in South Bend, IN White with blue leather. Under 100K for about $6500.
It seems like the only thing I have done many times on the car is brake jobs. The only thing that has been a pain is the windshield wipers. I cannot get them to adhere to the glass and big areas are missed. I even tried the ANCO with guranteed glass contact and there was no improvement.
1997 GS 327,500 miles avg 16city/25 highway. Engine still runs strong. Just a little bit of smoke, still original engine. all the common problems which have been identified I have repaired in the past two years. I consider it part of maintenance especially with the mileage. All repairs I do myself. with the exception of control arm bushing along with new coil springs. what a difference. The cars still looks like new for factory (light gold). FYI considering from day 1 (0 miles to 270,000+ miles it was a taxi on Chicago city streets). My father took exceptional care of his car during its service years every month routine maintenance (oil, etc). Upon retirment form taxi service the car was stripped, repainted to original color and buffed. The Interior was also stripped and cleaned along with new factory carpet. Experience well mechanically maintained vehicle will last.
Hey all..My 1997 Grand Marquis is in perfect condition since i got the intake manifold fixed.it set me back $800 to get it fixed but it was well worth it.At first i thought it was just running hot intill i saw smoke coming from the hood.Now its my Ac i think i need some Freon since its blowing hard hot air..Yea i dont think i would be feeling anything if my hose had a hole in it.
For all of you that think that you have a lot of life left in your 97-98 Mercury Grand Marquis just wait till the plastic intake manifold cracks. Very common problem. Makes an excellant car into a piece of junk.
