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.

    Notice coolant puddle under drivers front side bumper. Went to Ford dealer. Was advised at 2 separate dealerships that I needed a new radiator installed. Had it replaced as advised. Service tech said they had seen others like this, but normally around 70k miles. $1500.00 kick in the nuts for a 3 year old truck.

    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.

    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.

    slowly used antifreeze for 3 years.
    It became a real problem this month.
    Still waiting for it.
    I was told a bad radiator hose for $375.00.
    I have never heard of a radiator hose going bad in three years esp. when thats where you look for leaks.
    I am going to question the repair.
    it caal for replacement of the radiator and egr valve. not hose.
    Am i being Hosed

    leak driver side lower radiator. For the amount of money paid for this truck at least make a solid cooler, cost cuts to manufacture and still sell the trucks at an outrageous price. Ford you should be ashamed. This is why made in the USA doesn't account for crap anymore.

    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
