NHTSA Complaint #10205764 — 2005 FORD F-350 SD

I HAVE A 2005 FORD 350 SUPERDUTY 6.0 DIESEL TRUCK. I PULL A LARGE 5TH WHEEL UNIT. IT IS WITHIN THE WEIGHT RANGE INDICATED BY FORD. I HAVE INSTALLED A THERMOCOUPLE GAUGE TO MONITOR THE ENGINE EXHAUST TEMPERATURE. I WAS TOLD BY FORD DEALER THAT THE NORMAL EXHAUST GAS TEMPERATURE (EGT) SHOULD BE BETWEEN 750 AND 900 WHILE PULLING THE UNIT. UNDER A NOMINAL HILL CLIMB, I NOTED THE EGT NEVER GOT BELOW 1000, EVEN WHEN THE TRANSMISSION SHIFTED TO A LOWER GEAR. IT WAS HARD KEEPING THE EGT UNDER 1400. I HAD TO TRAVEL AT 55 MPH AND IN 4TH GEAR TO MAINTAIN THE 1000 DEGREE TEMPERATURE BOOST WAS BETWEEN 24 AND 28 PSI. NEAR THE TOP OF A CLIMB, THE TURBO HOSE BLEW. THE DEALER SAID IT WAS A DIRTY GATE VALVE OR DIRT IN THE VANES OF THE TURBO. DURING THE VACATION THEY REPLACED THE GATE VALVE AND THE TURBO. AFTER VACATION AND WITHOUT THE 5TH WHEEL ATTACHED, I NOTED THE EGT, UNDER NORMAL STREET DRIVING, RUNS AT 800 TO 1000 DEGREES. IF THIS IS AN INDICATION OF THE ENGINE/TURBO DESIGN, THIS ENGINE IS DOOMED TO FAIL. I BELIEVE FORD SHOULD HAVE KNOWN THESE ISSUES BEFORE THEY SOLD THESE TRUCKS. I KNOW THE TURBO WILL FAIL AGAIN. IF THERE IS RECOURSE, I WOULD LIKE TO KNOW. *JB
