The recall was not on the radiator. It was to install the venturi tee fitting on the coolant hose from the radiator to the degas bottle. Ford did allow for the radiator to be replaced under warranty if it was leaking at the time the recall was being performed but not after the recall was done. Now there is a TSB
for repeat leaking radiator that has the tech moniter the engine oil temp and coolant temp and if the oil is over 8 degrees hotter than coolant temp you are to replace the thermostats and leaking radiator, but the radiator can only be covered under warranty if the thermostats need replacing. And yes ford does call for the thermostats back and if they test good they do not pay the dealer for the warranty claim on the leaking radiator.
Doesnt this TSB
say to replace the radiator anyway? Or does it not specify which warranty (radiators or thermostats)?
09-23-1 6.4L DIESEL ENGINES - REPEAT RADIATOR LEAK - BUILT ON OR BEFORE 9/14/2009
Publication Date: November 9, 2009
FORD: 2008-2010 F-Super Duty
Some 2008-2010 F-Super Duty vehicles built on or before 9/14/2009 and equipped with a 6.4L diesel engine may exhibit repeat radiator leaks due to malfunctioning (hyper-extended) high temperature thermostats.
Follow the Service Procedure steps to correct the condition.
Verify the coolant leak is from the radiator, refer to pin point test (PPT) A found in the Workshop Manual (WSM), Section 303-03.
Verify the venturi tee is installed.
If installed, confirm it is installed correctly (note - orientation direction on part). Refer to applicable Field Service Action (FSA) for vehicle built on or before 5/15/2008.
If not installed, install per applicable FSA on vehicles built on or before 5/15/2008.
Prepare the vehicle for a test drive.
If the coolant leak at the radiator is large enough to cause an unsafe test drive or potential for engine/vehicle damage, proceed to Step 5.
Before driving the vehicle confirm the coolant level is at minimum level or above in the degas bottle. If required add 50/50 mix to coolant bottle.
Test Drive - use an Integrated Diagnostic System (IDS) or equivalent and monitor engine oil temperature (EOT
) and engine coolant temperature (ECT) parameter identifiers (PIDS).
at 195 °F (91 °C) drive on the highway unloaded at 55-70 MPH (89-113 Km/h) constant speed to observe EOT
and ECT temp.
Test results/next steps:
is less than 8 °F (4.4 °C) higher than ECT, and the coolant temp fluctuates roughly 5 °F (2.7 °C) - the thermostats are okay and do not need to be replaced. Replace just the radiator. Refer to WSM, Section 303-03 (Engine Cooling).
exceeds ECT by greater than 8 °F (4.4 °C) or if the ECT readings fluctuate 10 to 12 °F (5.55-6.66 °C) roughly every 30 seconds - replace both thermostats and radiator. Refer to WSM, Section 303-03 (Engine Cooling).
If vehicle is not drivable and the coolant leak is found to be from the radiator, remove and replace both thermostats and radiator. Refer to WSM, Section 303-03 for both radiator and thermostat removal procedure and approved cooling system draining, filling and bleeding procedures.
