Three problems related to radiator have been reported for the 2011 Ford F-250. The most recently reported issues are listed below.
The truck that I own has no accidents, no damages, 75k miles on it and the radiator is prematurely failing. This coolant leak on the lower driver's side is a reoccurring issue with this model vehicle and would cause the engine to overheat. Ford is aware of the issue and has refused to recall the part.
The contact owns a 2011 Ford F-250. The contact stated that after coming to a stop, there was an abnormal odor coming from the radiator. The contact noticed coolant leaking from the radiator. The failure recurred numerous times. The vehicle was taken to a dealer where it was diagnosed that the radiator needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 88,000.
Vehicle primary cooling system (radiator) began leaking where the aluminum coils are attached to the plastic tank. I took vehicle to Ford dealer for inspection and they verified. Leak was slow for first couple of weeks, then progressed. Replacement was inserted before radiator leak could cause further damage to vehicle or persons. This is a very common occurrence with this year/model and owners feel this should be addressed with a recall from Ford motor company due to inadequate testing or product specifications. The public rate of occurrence is very high. Of course fomoco will not publish data until forced. Reports of radiators failing < 50,000 miles is not uncommon.
