FORD 6.4L DIESEL ENGINES (2008-2010) IN F-250, F-350, F-450, AND F-550 TRUCKS CONTAIN RADIATORS THAT WERE IMPROPERLY CONSTRUCTED AND UNABLE TO WITHSTAND ENGINE PRESSURES AND LEAK COOLANT, AND CAN CAUSE CATASTROPHIC ENGINE FAILURES DUE TO OVERHEATING. FORD REPLACED COUNTLESS RADIATORS IN ITS 6.4L VEHICLES UNDER WARRANTY AND ISSUED A NUMBER OF SERVICE BULLETINS RELATED TO ITS 6.4L RADIATOR FAILURES. HOWEVER, EVEN ITS REDESIGNED RADIATORS CONTINUE TO FAIL. IN OUR VERY LOW MILEAGE F550 DIESEL, THE RADIATOR FAILED AT 23000 MILES EVEN AFTER BEING INSPECTED BY FORD AND "APPROVED" AS ADEQUATE. FORD REFUSES TO PROVIDE A FIX. THE FORD DEALERSHIP TELLS US THAT SOME CUSTOMERS HAVE REPLACED RADIATORS AS MANY AS 10 TIMES, OR MORE. AN INTERNET SEARCH (E.G., GOOGLE) FOR "FORD 6.4L RADIATOR" SHOWS COUNTLESS OTHERS HAVE EXPERIENCED MULTIPLE RADIATOR FAILURES. AGAIN, FORD IS UNWILLING TO RECALL THE DEFECTIVE ENGINE PARTS OR PROVIDE A WARRANTY REPLACEMENT. *TR
