As of April 18,2011 my radiator is cracked and I have to replace it for the third time. My Mercury Mountaineer is a 2006 and in 2008 I had to replace the radiator which cost me around $800 with labor and here we are in April of 2011 and I have to replace my radiator again. This is costing me to much money and with all these complaints about the radiator, you would think that they would have a recall on the 2006 Mercury Mountaineer radiator. Somebody needs to do something about this because a radiator should not have to be replace 3 or more time in less then 5 years. Please do something about this. Thanks

2006 Mercury Mountaineer driving on the highway, suddenly the coolant temperature went up crazily and the engine sounded horrible and lost power. Fortunately stopped by the roadside and found the radiator was leaking and coolant is almost empty. Searched around the web and found that for 4.0 engine from Ford and Mercury, this is pretty normal problem due to a design defect. People are changing radiator every year. Never heard such ridiculous thing that nowadays the radiator last so short time. It should last life time of the car. Ford apparently knew it, however, they only announced a tsb in 2009 when most of the warranties were gonna expire. They should issue a recall. This is a design problem and it poses life threatening risks. I guess they just don't care about customers. The customers need to repair out of they own pockets, which support Ford's chain dealers service departments. Well, sounds a good plan for them. Well, the customers are not stupid. They are change to Japanese cars, which have far less problems. I will never a Ford?Mercury car and would be glad to see them go bankruptcy.

My 2006 Mercury Mountaineer radiator needs replacing because it is busted. I only have an estimate of 65,000 miles on it. The part will cost me $285 not including the labor. This vehicle is only 4 years old how could a part like this already need replacing.

Radiator leak. Complete radiator was replaced with new radiator and hoses and still leaked. I believe Ford's radiators are defective.

Radiator began leaking in my 2006 Mercury Mountaineer at 51,500 miles.

The radiator in the 2006 Ford Explorer/Mercury Mountaineer is a weak link in the vehicle. My radiator is leaking and I'm not the only one, I have found other complaints of this on other Explorer and Mountaineer of this year.
- Lacombe, LA, USA
The contact owns a 2006 Mercury Mountaineer. He has experienced several failures with the vehicle. In an attempt to diagnose the failure the vehicle was taken to several different repair centers, to no avail. When contacting his local dealer the contact was advised that the vehicle would need several repairs including a failed radiator, thermostat, water pump, brake drums, rotors and a grease treatment, all at his own expense. The manufacturer was contacted and would not offer any assistance. The failure mileage was approximately 65,000 and the current mileage was 107,253.

Broken radiator in my 2006 Mercury Mountaineer with 52,000 miles.
- Peabody, MA, USA
Cracked radiator with only 41,000 miles. Dealership indicated repair cost would be $1,000. When I questioned possible defect they said they had no recalls but also indicated they had just replaced another one last week. I called another dealership to check price they estimated $750 and also indicated they had to replace 2-3 in the last few months. Judging from this site and others this is a major defect with 2006 Ford Explorer and Mountaineer. Why doesn't anyone hold the manufacturer accountable?

Leaky radiator was 1st detected by myself but mechanics were unable to determine the leak because anti-freeze was not visibly leaking but the resevoir was always empty. I was told it was a problem with my tires. The problem was not addressed by mechanics until they saw that the radiator could not hold coolant any longer. Now it has been identified as having a hole in the radiator.

Had to replace radiator at 36,500 miles. Purchased vehicle on Sept 9, 2009 as a certified Mercury vehicle and within 3 months had a leak in the radiator that needed to be replaced.

Had to replace two radiators within 30,000 miles of replacement. Exactly how many complaints, or should I say deaths (?) are needed to trigger an investigation of a company gladly receiving assistance while outputting inferior vehicles. No vehicle manufactured in 2006 should need three new radiators within 3 year and 70K miles. Stop letting Ford off the hook and get serious about getting to the bottom of their issues. Just do a search on 2006 Mercury Mountaineer and you will clearly see there are issues with the cooling as well as the automatic transmission. In fact, our model has the same issue that others have reported with the automatic transmission and it will sometimes no moves gears, slip a gear, and tug like it is pulling out of mud at a stop light. Open a full blown investigation into their lack of quality control and the lack of professionalism on the part of the dealerships for not reporting this to corporate.

I have had to replace three radiators in my vehicle since purchasing the auto in Sept of 06. The first one was replaced at 26,048 miles (under warranty) the 2nd 33,202 miles (under warranty)and the last one occurred with 53000 miles (no longer covered). Each time they replaced the radiator with a brand new one. I have also contacted Ford / Mercury to look for assistance on this problem and why this is happening and they directed me back to the dealership. I do not believe this is normal wear and tear on my vehicle.

There is a big problem with the 2006 Mercury Mountaineer and Ford Explorer with the V6's radiator. At very low mileages the radiator separates at the seams on the side causing a leak. This is very dangerous and expensive. I have done research on the problem and it is terrible that you only get 40K or less out of a radiator. There needs to be a recall on this problem!!! please help.
