2004 Mercury Grand Marquis Owner Comments

problem #4

Nov 052011

Grand Marquis

  • 98,116 miles


I had what seems to be a simple coolant leak but it turned out to be the plastic intake manifold cracked. Putting a plastic part on top of a motor seems to me a failure of engineering on the part of Ford. I did not receive any call back for this part. I did some searching on the web and found that many Ford owners had the same problem. I plan to call Ford company on Monday. Do you have any info for me on this subject. Thank you.

The contact owns a 2002 Buick rendezvous. The contact started the ignition and the temperature gauge displayed a hot level reading with the illumination of the coolant warning indicator. The engine began to overheat. The vehicle was taken to an independent mechanic where they replaced the head gasket. The VIN was unavailable. The failure mileage was 96,000.

Intake manifold cracked, needed replacement. This is a plastic component which is not designed for cold weather climates. This is the second time (second car) that this has happened to.
