4 Radiator problem of the 1997 Mercury Grand Marquis

Failure Date: 11/01/2002

In November of 2001 I left for a trip in my Mercury, about halfway to my destination, the intake manifold of my car failed, the entire contents of my coolant system evacuated in less than one minute. I thought I had ruptured a hose, upon closer inspection; it appeared to me that a hose had blown close to the engine block in a place that I could not see well. A mechanic at the dealership informed me the next day that the intake manifold was plastic and that it had cracked. But luckily for me he would help me out, he happened to have a spare manifold that he had taken off of another car like mine. Apparently, someone had blown a head gasket in their 97 Grand Marquis and the owners were convinced that it was the intake manifold. So the mechanic replaced their manifold and kept their old one that was still good. The mechanic was willing to sell me the manifold and replace the broken one on my car for about half the price it was going to cost me to have the dealership replace it. The dealer would have billed me nearly $600. 00, so I told him to perform the repairs. He told me that they had some problems with the plastic intakes and had redesigned them. The one he placed on my car was supposedly of the new design. . Read more...
