Complaint received via E-mail. We just had our plastic intake manifold replaced, costing $852.28. After so many miles, the pressure makes the front end of the manifold crack and leak. Our mechanic has replaced many of these faulty plastic manifolds, and he said eventually all early models of the Mercury Grand Marquis will have to have this part replaced. He said the Ford company has replaced this manifold on later models, starting with 2002 with an aluminum part where the problem was.

Intake manifold had to be replaced. The manufactured manifold is made of some sort of plastic. The replacement manifold is also made of the same sort of plastic, but has been revised. Lincoln Mercury considers the new manifold improved. The new one has an aluminum metal on the front section of manifold where alternator support bracket bolts in to hold back of alternator. Speaking to many garages dealing with these same type of vehicles it was stated that this is a common problem with these types of vehicles. Reasoning believed to be is from the vibration of alternator bracket where it bolts into the intake manifold. The intake manifold between the 2 mounting bolts of the alternator bracket cracked across the 2 bolts.

My car (1996 Mercury Grand Marquis) developed a crack in the intake manifold leading to complete loss of coolant and overheating while traveling through Wyoming. It was then towed to a small town repair shop, where this problem was brought to my attention, and that many cars had a recall for this. Unfortunately, for civilian cars there is no recall which led to a repair cost of $1132.
