A coolant leak from the radiator can be caused by a defective thermostat bypass. This can cause pressure spikes in the cooling system, which leads to radiator failure. The thermostat assembly and radiator should be replaced.

    Radiator leaking and Ford wont stand up and do what's right. They know there is problem here and still wont issue a recall. This is the first Ford I've ever bought and will be the last. My solution, trade it off for a Chevy. I don't really want to give the government any more money but I sure wont buy an import.

    I too have a radiator leak. It's up top where the aluminum and the plastic meet. I went to the dealer and asked if they had a recall. He said "no" here is the customer service line if you want to complain. Thanks Ford! My friend owns a business and has 4 that are all leaking in the same spot.

    Truck died while driving, wouldn't start again- took to shop, they said no fluid in the radiator caused the engine to lock up- no repair done as this is quoted at 16,000.00 for a new engine. Even though only 42000 miles, it was months just past the 5 year warranty.

    Coolant leak from radiator. I had to have the radiator replaced, the dealer checked the system using TSB 10-5-2 but found no faults. After reading about 2008 Super-Duty radiator problems by the hunderds it would seem to me that there is a systmic problem that Ford is not owning up to.
