Coolant Leak from Radiator on Ford F-250 Super Duty

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.

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

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.

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.

Dealer haut informed me I need a new radiator. Leaking from the side tank. A class action law suit should be addressed if Ford won't fix this known $1500 problem. This is mind blowing that I spent this money and less than three years the radiator which is a patented part must be replaced. Someone needs to make one that is more dependable! Disgusted and shopping for a new Chevy or dodge

Get the radiator flushed every 15,000 miles and keep up on all of the recommended services..I even change the oil and fuel filters more often,to keep it running at it's best. This seems like a defect, not a "normal wear and tear" issue.
