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.Google+

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 leaking from radiator. Dealer said radiator had two leaks. Had to have radiator replaced.

Leaking yet again. This will be the 5th radiator.
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.
