“While driving on freeway at freeway speed, my 1997 grand Marquis, ls was running at normal temp. All of a sudden within a matter of a minute or two, the temp gauge maxed out, car started smoking, all coolant was lost. I pulled over immediately, and upon inspection I found that the plastic intake manifold had cracked approx a 3-4 crack. I was stranded, had to tow my car approx 134 miles to get home. This is a $269.99 part not to mention the gaskets, anti-freeze and labor involved to fix. I feel this is a manufacturer defect and I should be reimbursed for the cost of the part at the very least.”
NHTSA complaint #10158905, filed 2006-06, 2 miles“My 1997 Mercury grand Marquis overheated and blew steam and antifreeze throughout engine compartment and on to windshield. This was caused by the a crack in the water jacket portion of the intake manifold. I was told by the dealer that this is a common problem and manifold has been redesigned but is not covered by a recall and the repair expense ($989 plus tax) would be my responsibility. He also stated that this identical problem on police cars and some others is covered. A call to ford motor company rendered same results. I bought this car new and it has only 60000 miles. …”

What appeared to be smoke was pouring out between my hood and cowling. I managed to stop the car and lifted the hood. Antifreeze smell was strong, water was shooting into my alternator and the engine was excessively hot. I had the car towed to a reliable garage and they determined that the intake manifold had split open, but the smoke was actually steam and no fire had ensued. …”
