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.

Three weeks after my last camping trip my truck is sitting in my driveway and starts to leak from the radiator. Went to the local Ford Dealer and they told me I need a new radiator.

Second radiator leak, same front side, drivers, near bumper. Came out for lunch, puddle under the truck this time. Ford says it will be my problem to solve in next go around (I will be out of 36K mile bumper to bumper). This will be the third radiator. Price to fix, $1700.00
