Service bulletin TSB-14-0198

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

SSM 492102020-10-06. Service bulletin. Some 2009-2020 Ford and Lincoln vehicles equipped with turbochargers may exhibit an oil leak from the turbocharger oil supply or return tubes, O-rings or 6.7L pedestal gasket. Although oil may collect on the turbocharger, it is very rare for a turbocharger to leak oil. To isolate the source of the leak, refer to Workshop Manual (WSM), Section 303-00 General Information > Diagnosis and Testing > Engine > Engine Oil Leaks - Fluorescent Oil Additive Method procedure. When an oil leak is present at a turbocharger oil supply or drain tube, remove the affected oil tube and inspect for damage, and replace the O-ring seals, pedestal gasket or oil tube as required. Refer to WSM, Section 303-04. For claiming, use the affected oil tube or pedestal gasket as the causal part and applicable labor operations in Sections 6 and 9 of the Service Labor Time Standards (SLTS) Manual.
SSM 479482019-05-07. Service bulletin. SSM 47948 - 2010-2019 Various Vehicles - Turbocharged Engines - Oil Supply Filter Replacement When Replacing The Turbocharger Or The Turbocharger Oil Supply Tube For 2010-2019 vehicles equipped with turbocharged engines, when diagnosing and/or replacing turbo related concerns, all steps within the Workshop Manual (WSM) procedure must be followed including replacement of all mandatory discarded parts. When specified in the WSM, the turbocharger oil supply filter must be replaced whenever the turbocharger or the turbocharger oil supply tube are replaced. Turbocharger bearing failure may occur if oil starvation occurs due to a restricted filter.
SSM 477972019-04-08. Service bulletin. Some 2009-2017 Expedition/Navigator, 2009-2014 F-150/Mustang, 2008-2009 Sable, 2008-2019 Taurus/Flex/MKT, 2013-2019 Police Interceptor Sedan/Utility, and 2011-2019 Explorer vehicles may exhibit inoperative or intermittent HVAC blower motor function at various fan speed settings. This may be due to a poor electrical connection at the blower motor speed control. If the blower motor speed control is determined to be the causal part, replacement of the electrical connector pigtail harness (14S411) to the blower motor speed control is also recommended to avoid repeat repairs. Refer to Wiring Diagram, Cell 5 for recommended splicing procedures. Refer to Wiring Diagram, Cells 54/55 to obtain the service pigtail connector part number.
SSM 476622019-01-07. Service bulletin. For 2010-2019 vehicles equipped with turbocharged engines, when diagnosing and/or replacing turbo related concerns, all steps within the Workshop Manual (WSM) procedure must be followed including replacement of all mandatory discarded parts. For all turbocharged engine applications, the turbocharger oil supply filter (6C683 gas engine/6L625 connector style or 6A968 diesel engine) must be replaced whenever the turbocharger or the turbocharger oil supply tube are replaced. Turbocharger bearing failure may occur if oil starvation occurs due to a restricted filter.
SSM 472302018-05-21. Service bulletin. Some 2007-2016 Edge/MKX/Flex/MKT/MKZ/MKS/Taurus/Police Interceptor Sedan/Explorer/Police Interceptor Utility vehicles equipped with AWD and built on or before 30-Jun-2016 may exhibit a propane or natural gas odor during idle or low speed driving. This may be due to break down of the power transfer unit (PTU) fluid caused by excessive heat. If the source of the odor is identified as originating from the PTU, an idler bearing repair kit is available to repair the PTU. Refer to the Workshop Manual (WSM), Section 308-07. If the PTU is determined to be repairable, utilize kit GB5Z-7P258-A and the included instruction sheet. For claiming use causal part 7P258 and applicable labor operations in section 07 of the Service Labor Time Standards (SLTS) Manual.
SSM 460852017-08-01. Service bulletin. The Powertrain Control/Emissions Diagnosis (PC/ED) manual has been revised for diagnosing electronic throttle bodies (ETBs). The ETC_ACT and ETC_DSD PIDs should not used to diagnose possible ETB concerns. The IDS has a limited refresh rate when reading these PIDs and cannot display quickly enough to validate a concern. The PCM automatically monitors these inputs more accurately and will set diagnostic trouble codes (DTCs) when appropriate. Using these PIDs for diagnostics will lead to inaccurate results and improper ETB replacements. If a concern is intermittent and no DTCs are present, refer to historical DTCs and the PC/ED, Section 3 No DTCs Present Index chart for further information.
SSM 465222017-08-01. Service bulletin. 2013-2017 Edge/MKX/Flex/MKT/MKZ/MKS/Taurus/Taurus Police/Explorer/Explorer Police/Continental vehicles equipped with a 3.5L or 3.7L engine, all wheel drive (AWD) and a power transfer unit (PTU) that is being repaired or replaced for an internal failure must also have the vent hose replaced due to contamination in the hose.
