Carburetor Problems of Mercury Grand Marquis - part 1

The intake manifold for 4. 6l engines are plastic and has been a problem since 1996 when they were recalled and Ford still used the plastic manifold anyway. My manifold cracked right behind the alternator spewing antifreeze all over the engine compartment. This has been a problem and Ford will not cover the repair or change the manifolds. Dt.

Consumer notice coolant smell inside vehicle while traveling soon after notice temperature gauge rising with indication light flashing. Consumer pull vehicle over look under hood and notice coolant under hood and ground vehicle was service intake manifold need to be replace. Mr the consumer states that Ford acknowledges this problem to fleet owners and has a recall, but aren't addressing the problem. The consumer states that he has made the repairs with parts purchased from the Ford dealer. (cracked along the seam, dumped coolant all over the upper engine and onto the ground).

Consumer states that intake is cracked. Dealer was contacted.

The plastic intake manifold ruptured causing coolant to enter the cylinders and may have caused crack in engine block.

Plastic intake manifold ruptured causing coolant to further enter cylinders and may have caused crack in engine block-this vehicle has been exceptionally well cared for including oil changes each 2000 miles-Ford & CO have essentially said I'm on my own-this integral part should certainly have been manufactured to a greater and not a minimal standard.

Plastic intake manifold split, causing coolant to enter into cylinders and appears may also have cracked engine block-seems Ford & CO could care less-this vehicle has otherwise been extremely well cared for including oil changes every 2000 miles.

The plastic intake manifold developed a fatigue crack at the coolant crossover duct. This caused coolant loss and an overheating condition. The factory replacement part is made of metal.

I purchased this vehicle which had 86,715 miles on it. Shortly after the purchase I noticed the engine would spark knock anytime the car was put under a load when the transmission was in high gear and in overdrive. Due to my schedule I did not take the car in for this problem until the drivers side window fell down while attempting to roll it down. After spending 741 dollars to repair those problems I drove the car approximately 50 miles and steam came from under the hood. The car was towed back to the dealer. The dealer evaluated the problem and advised me that the intake manifold was broken. I was advised the repair cost was $893. 75 including towing. Iwas advised by both the dealer and the Ford customer service line 1-800-392-3673 that there was no recall or warrenty for this problem. By finding this web site I have found 16 other simular conplaints.

While driving 35 mph, the consumer noticed steam coming from underneath the hood. The consumer then contacted the dealer, who determined that the plastic intake manifold had overheated, which created an antifreeze leak. The consumer states that the plastic manifold had cracked and was replaced with a metal one. The bill and the letter sent to rda group and Mercury is attached, regarding the faulty part and the request for reimbursement.

Intake manifold is plastic, new part half cast alum(front section)only called Ford defect was changed in yr. 2000 but not a recall, ?? why dealer said has replaced quite a few of these Ford mich. Said the same thing but no recall why!!!!!.

Ford motor company recognizes several vehicles affected by this condition, including the crown victoria, mustang, Lincoln town car, and Mercury cougar, all with the 4. 6l engine built with a plastic intake manifold, yet Ford refuses to acknowledge the Grand Marquis. Fortunately, our experienced failure occurred at a low speed (approximately 20-25 miles per hour) as my wife was driving into our subdivision. However, the amount of steam (which she immediately thought was "smoke") caused her to panic and nearly flee the vehicle. Had this occurred at highway speeds in traffic, this failure surely could have caused a potentially harful, even fatal incident. Ford has admitted the failure, but evidently does not consider it of noteworthy concern for most vehicles equipped with this popular and widely used engine package. (see Ford document #97m91) it is frustrating that they are unwilling to correct the problem, especially since it is a known and acknowledged defect with the engine in question. This is a costly and potentially harmful, if not potentially life-threatening defect. The super-heated steam produced by the rupture at the top of the engine (right behind the fan, no less) billowed out in a plume of steam that made road-vision nearly impossible, not to mention causing a definitely distracting panic situation! I have contacted Ford, including my local dealership (moyer Ford, foley alabama), their custuomer service "hotline" and jonathan grimm at Ford whq. All have repeated the mantra, "we're sorry, but we can't do anything for you in this situation. " on the internet, I have found numerous similar complaints, and a local mechanic has stated that he has had to replace a number of the plastic manifolds as well. I feel this is a potentiall serious problem that Ford is willing to ignore! I want to call attention to this matter for the potential safety of others, as well as to reclaim the costs of repairing an admitted defect in Ford's design and manufacturin.

Intake manifold required replacing. It had split across the front seam causing antifreeze to spill all over the engine. Our VIN number is not on the recall list even though others of the same make are. The split was across the front seam of the plastic manifold. New ones have aluminum liners in them, which makes me believe that the company knows that it`s a current problem.

While driving on highway intake maninfold broke,causing fuel and coolant to leak. Engine was destroyed. Dealer contacted. This was a common problem.

Consumer states because of a design defect, heat builds up in a plastic manifold which caused a crack. Consumer is suggesting the plastic manifold has to be replaced with an aluminum-reinforced manifold.

Coolant is leaking from intake manifold. Dealer contacted. Feel free to provide any further information.

Intake manifold cracked while driving. There were recalls on the Ford with the same engine. No injuries.

Plastic intake manifold has separated from the vehicle while driving 40 mph. Dealer and the manufacturer were notified. Feel free to provide any further information.

Intake nanifold was cracked. And leaked coolant from underneath the vehicle. Dealership was aware of problem.

While driving along a busy city street on a cold evening in January I noticed a cloud of steam behind me. It obscured my view of traffic behind me and their view of my vehicle. After pulling of the right-of-way, and examining the engine compartment, I recognized cooling system failure but was unable to identify the source of the problem. It was later determined that the "plastic" intake manifold had ruptured and sprayed coolant all over the engine cmpartment,and hot exhaust manifold, etclocal Ford dealers were closed and unavailable. Reputable auto repair garage performed the necessary repairs (6 hrs) this critical engine component should "never" fail. Ford quietly recalled police, fleet and emergency vehicles. Consumers were left to fend for themselves. They have ignored my request for financial assisstance.

The vehicles intake manifold developed a 4 1/2 inch crack at the front edge. This crack caused a total loss of all coolant.

The vehicles intake manifold developed a 4 1/2 inch crack at the front edge. This crack caused a total loss of all coolant.

The intake manifold on my vehical is the same that is on any 4. 6ltr engine that Ford has put into production in the years prior to 1998. When Ford went to a casted manifold. I know they have had several failures of this part. Even the local dealership parts man said that this part should be recalled. That tells me that they have had a high percentage of failures of this manifold. But instead the consumer has to put out around 500 dollars, to repair a defective part. Is there any recourse for this type of problem. I noticed several of the same complaints in your listing of failures.

Air intake plenum developed a crack which in turn sprayes coolant onto the rear of the alternator. I know there are many problems with this part but Ford will not replace it. There is a limited recall on this part but it begins less than 4 months after the build date on my car, even though the problem described exists on many earlier models. I would like my car included in this recall but am told no way by Ford. Any help in this matter would be greatly appreciated.

The water jacket on the intake manifold cracked right behind the alternator the dealers cary atleast 6 manifolds in stock at all times they had the problem on other vehicles and told me mine wasnt on the list.

My primary complaint is the stress crack on the intake manifold. This is a known problem by Ford, and has been the subject of a recall program for their fleet vehicles only. The coverage is for 7 years from the vehicles warranty start date, with no mileage limitation. It covers the intake manifold for 4. 6 l sohc engines on 1996-2001 crown victoria police vehicles, certain 1998 through 2001 crown victoria taxis and certain 1998-2001 Lincoln town cars, all using the same intake manifold as that on my Grand Marquis (same part number, same part!). The recall program is 01m02. The stress crack caused complete coolant loss and overheating of the engine at highway speeds and the release of coolant onto the windshields of following vehicles. In addition, the reel-type electric window system in the car fails in more than normal fequency. I have had three failres in the past two years.

While accelerating onto freeway, noticed coolant odor; watched heat gauge carefully and drove to mechanic. Plastic intake manifold had cracked across the front and all collant was lost. Costly repairs followed. I have written to the Ford motor CO. And requested reimbursement. Have not heard from them at this time.

The vehicles intake manifold cracked causing steam to start coming from under the hood while driving, the consumer is requesting reimbursement for the defective component. Nlm.

The front of the intake manifold cracked causing the antifreeze to leak out onto the engine causing a lot of steam.

This plastic part split along the seam. It's a pricy repair that looks like a wanufacturing defect.

When driving no more than a block consumer noticed temperature gauge go up. Also, steam was coming from engine compartment, all coolant was lost. Consumer contacted dealer. Dealer noticed intake manifold needed replacing. The consumer states similar year and models had a recall and this vehicle should be included.

Intake manifold is plastic and has the potential to melt. Consumer is concerned that this could eventually cause other problems to occur, such as engine over heating. There are stress cracks where the alternator is attached to plastic manifold. The dealer informed consumer that the defective part should be under recall but it wasn't. At first, Ford stated they would pay for the part, however they have now declined. This is a saftey hazard as smoke emits from the engine area obstructing the view of the driver.

While driving 40mph & was coming to a stop noticed steam coming from under hood. Intake manifold had cracked. Been in contact with dealership & manufacturer. Manufacturer did not offer any assistance regarding cracked manifold. Intake manifold was made of plastic.

These were replaced in state cars with aluminum intakes for free. We feel we should get this replaced free also with aluminum.
