2006 Mercury Mountaineer. Consumer writes in regards to failure of the water manifold housing. The consumer stated he was driving 70 mph, when the engine light illuminated. The vehicle began to overheat and steam was coming from under the hood. The water manifold housing had come apart, allowing water to boil out. The housing was plastic and made of two parts. The top and bottom were glued together and within the total circumference of about 18 inches, there were only three bolts between the top and bottom housings to secure the two parts together, except the glue. The consumer believed the construction was not enough to keep them from separating under pressure. It appeared, the design created a tendency for the top plate to pull away from the lower housing. The consumer attempted to install a new housing, but he discovered the engine was misfiring, so the vehicle had to be towed to the dealer, where the long block assembly was replaced.

Had a leak in my radiator when the truck had less then 25,000 (summer of 2009?) miles logged on it. Took it to the dealership and they replaced it for free because it was under warranty. Again this spring, with my odometer at 52000 miles, it has another leak and I was quoted $800 to get it replaced because it is no longer under warranty. This is B.S.! obviously it is a known problem. I have not had it fixed yet because I don't have the time to leave it at the dealership, or the $800 to replace a radiator that should not need to be replaced after such a short amount of use. This issue needs to be rectified by Ford! it has made me never want to buy another Ford vehicle, ever!

The radiator keeps leaking, first dealer said there was nothing wrong with the vehicle, I am always putting coolant in the vehicle. You can smell the coolant as soon as you open the hood. This has been an ongoing problem since I had 53,000 miles and now that I have 122,000 miles it is getting worse and has to be repaired again.

In July 2009 at 40000 miles the radiator had a hairline fracture and the radiator had to be replaced, paid out of pocket by owner. In March 2010, at 60000 miles, another radiator is being put in this vehicle, again out of pocket expense for owner. There should not be a need for a vehicle to have had 3 radiators at 60000 miles. The dealership states this is a known issue with this model and that these are poorly placed and manufactured radiators. Ford/Mercury should recall these vehicles and reimburse out of pocket expenses for anyone that has proof of radiators being replaced.

The radiator coolant system is junk. Busted seals and hoses all the time. I am beginning to think this car is a lemon. I replaced my radiator less than 1 year ago, had the part replaced with the factory part Ford supplies and once again I have a busted seal and have to replace the radiator again. When are they going to recall this part? seriously I've done my research and the radiators on these vehicles busting isn't an isolated incident. Is Ford going to pay $400 dollars every 6 or so months to replace my radiator. I wish someone would file a class action law suit or something.

I have leak in my radiator, and after doing some research on the internet I found out that there is alot of complaints about that type of radiator in that vehicle, and every one of the cases is identical and now I am the next victim of this radiator failure. Some thing needs to be done about the radiator problems Mercury is having on the 2006 Mountaineer. My vehicle is very well maintained and don't even have 60,000 miles on it yet.I completely understand there will always be some kind of mechanical issues to deal with nothing last forever, but most radiators usually outlast the vehicle.

My 2006 Mercury Mountaineer radiator is cracked. I 've asked mechanics and they told me that the radiators have had problems. I went online and there seems to be the same problem that I am having. I'm sure Ford is aware of the problem but they are not taking any action towards the problem. Can you help us.
