SSM 523352024-03-20. Service bulletin. ENGINE AND ENGINE COOLING. For 2015-2024 Ford and Lincoln vehicles equipped with turbocharged engines and customer concern of an engine oil leak, refer to Workshop Manual (WSM), Section 303-00 for oil leak inspection and testing methods. Ford has evaluated turbochargers replaced for oil leak symptoms and although oil may collect on the external surface of a turbocharger, it is extremely rare for a turbocharger assembly to be the root cause of the oil leak. Careful inspection of the turbocharger oil feed and drain tubes should be performed along with the recommended WSM procedures as needed. Warranty claims for turbocharger replacement going forward will be assessed.
TSB 22-22482024-03-07. Service bulletin. ENGINE AND ENGINE COOLING. This article supersedes TSB 22-2201 to update the Service Procedure and Parts List. Some 2015-2019 F-Super Duty and 2016-2019 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit an oil leak from the oil filter, crankcase vent oil separator, oil cooler, or upper/lower oil pan. This may be due to the mating surfaces of the upper oil pan and the engine block or to a clogged crankcase vent oil separator.
SSM 516912023-06-16. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; POWER TRAIN. 2011-2023 F-Super Duty and 2016-2024 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit an elevated idle condition. During prolonged idle time, vehicles may experience this elevated idle to reduce unburned hydrocarbons from the SCR. The powertrain control module estimates hydrocarbon levels in the SCR and may increase idle speed to remove them. Idle speed will be increased to 1000 RPM for ambient temperatures near 26°C (80°F) and may increase to 1200 RPM at -40 °C (-40°F). Vehicles may exhibit exhaust smoke and diesel exhaust fluid smell during elevated idle condition. Exhaust smoke and smell condition will not affect reliability or durability of the engine. Power take-off (PTO) use and idle set point control will disable elevated speed. It is required that the operator monitor the vehicle and adhere to any Exhaust Filter warning messages.
SSM 512942023-01-31. Service bulletin. ENGINE AND ENGINE COOLING. Some 2016-2019 F-Super Duty/F-650/F-750 vehicles equipped with a 6.7L engine may require the lower intake manifold to be removed for various concerns. The WSM, Section 303-01, has been updated to remove the lower intake manifold leaving the crankcase vent oil separator attached. Both parts should be removed from the engine together to avoid discarding and replacing the crankcase vent oil separator.
SSM 512512023-01-05. Service bulletin. ENGINE AND ENGINE COOLING. Some 2011-2022 F-Super Duty vehicles equipped with a 6.7L diesel engine may exhibit a ticking noise at idle after an engine oil change. It is often referred to as Typewriter Noise because of its similarity to the sound of a mechanical typewriter. When engine temperatures reach 150 °F (65 °C) or higher, (from engine idle up to approximately 1700 RPM's), this noise can typically be heard at the front wheel well and is often isolated to the transmission bell housing or oil pan area. Typewriter Noise is not detrimental to engine function or durability and has no short or long term effects on the engine. Do not attempt repairs to eliminate this noise. This noise is characteristic of the 6.7L diesel engine and will typically cease or diminish significantly within the oil change maintenance interval.
TSB 22-23802022-10-31. Service bulletin. ENGINE AND ENGINE COOLING. Some 2017-2019 F-Super Duty chassis cab/dual rear wheel (DRW) pickup vehicles and 2016-2019 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit a concern of oil consumption in applications where the engine is idled for extended periods of time. This may be due to high crankcase pressure as a result of the crankcase ventilation filter element becoming restricted. To correct the condition, follow the Service Procedure to replace the crankcase oil separator and to inspect the turbocharger to determine whether the turbocharger needs to be replaced. Note: The new crankcase vent oil separator appears different from the old crankcase vent oil separator as it no longer includes a serviceable filter element.

Power take-off (PTO) use and idle set point control will disable elevated speed. It is required that the operator monitor the vehicle and adhere to any Exhaust Filter warning messages.
SSM 504482022-02-04. Service bulletin. FUEL SYSTEM, DIESEL; POWER TRAIN; ENGINE AND ENGINE COOLING:ENGINE:DIESEL. Some 2017-2022 F-Super-Duty vehicles equipped with a 6.7L diesel engine may exhibit a hard start, lack of power and/or runs rough concern with an illuminated malfunction indicator light (MIL) and diagnostic trouble codes (DTCs) P0087 and/or P008A. This may be due to low fuel level or fuel gelling in cold ambient temperatures. If no root cause is determined after normal Powertrain Control/Emissions Diagnosis (PC/ED) pinpoint test MA, recommend that the customer use a different brand of fuel and use Motorcraft® PM-23-A Diesel Fuel Anti-Gel and Performance Improver. Inform the customer that bio-diesel blended fuels have a higher occurrence of fuel gelling. Fuel gelling and or low fuel conditions causing a P0087 and/or P008A is not covered under warranty.
TSB 21-24042022-02-04. Service bulletin. ENGINE AND ENGINE COOLING; ENGINE. Some 2015-2021 F-150, 2017-2021 Super Duty and 2018-2021 Expedition/Navigator vehicles may exhibit poor air conditioning (A/C) performance, loss of airflow and/or engine cooling fans running continuously from high A/C pressures. This concern may be from the evaporator freezing up due to the evaporator temperature sensor being biased. To correct the condition, follow the Service Procedure steps to replace the evaporator temperature sensor.
TSB 21-24472022-01-01. Service bulletin. ENGINE AND ENGINE COOLING. This article supersedes TSB 21-2192 to update the Parts List and Issue. Some 2017-2019 F-Super Duty/F-650/F-750 vehicles equipped with a 6.7L may exhibit an engine oil leak. This may be due to the mating surface of the upper oil pan and the engine block.

SSM 503232021-12-26. Service bulletin. ENGINE AND ENGINE COOLING. Some 2017-2022 F-Super Duty and 2016-2022 F-650/F-750 with 6.7L diesel engines, 2015-2019 Transit with 3.2L diesel engines and 2018-2021 F-150 with 3.0L diesel engines may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P206C in the powertrain control module (PCM). Review of repair data supports that P206C is often the result of incorrect diesel exhaust fluid (DEF) concentration. Per Powertrain Control/Emissions Diagnosis (PC/ED) Pinpoint Test (PPT) RJ, a DEF concentration reading below 28% will set P206C and cause vehicle derate. If low concentration is suspected, drain fluid and replace with known good DEF before replacing any parts. Low concentration of DEF is not a warrantable condition.
20M06-S22021-11-02. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; ENGINE AND ENGINE COOLING:ENGINE:DIESEL; COMMUNICATION.

SSM 500662021-09-04. Service bulletin. ENGINE AND ENGINE COOLING. Some 2015-2019 F-Super Duty and 2016-2019 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit an oil leak from the oil filter, crankcase vent oil separator, oil cooler, upper/lower oil pan. This may be due to a clogged crankcase vent oil separator and/or a sealing concern. Do not remove/replace the engine front cover for upper oil pan leaks. Do not check for warpage on the upper oil pan. When the upper oil pan is not bolted to the vehicle, it has a natural tendency to twist slightly due to the manufacturing process for the pan and will not result in an oil leak. The Workshop Manual (Section 303-00 > Diagnosis and Testing > Engine > Engine Oil Leaks) provides information on the usage of fluorescent oil dye to locate the source of an oil leak. Refer to GSB Oil Leaks Weeps And Seeps for more oil leak diagnosis. Continue to monitor OASIS for updates.
