Service bulletin TSB-10-21-6

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 522432024-02-14. Service bulletin. When performing any transmission fluid change or topoff involving Motorcraft® Premium ATF, MERCON® V has replaced all versions of Motorcraft® Premium ATF and can be used going forward. Mixing Motorcraft® Premium ATF and MERCON® V in the same transmission is acceptable. After 31-Jan-2024, Motorcraft® Premium ATF will no longer be manufactured and will only be available until inventory depletes.
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.
DOR-M9J4S-072020-07-27. Service bulletin. These SKUs are Exhaust Manifolds with Catalytic Converters. The customer communication requested return of unsold inventory due to a loss of CARB certification. These SKUs can no longer be sold as they do not meet CARB standards, but parts on vehicles are not effected.
DOR-N3Z7B-032020-03-30. Service bulletin. This SKU is an Oil Dipstick. The customer communication requested return of unsold inventory to inspect the dipstick tube. The dipstick tube inner diameter may be small enough that it prevents installation of the OE dipstick.
SSM 482382019-11-05. Service bulletin. Some 2010-2012 Fusion hybrid electric vehicle (HEV), 2010-2011 Milan HEV and 2011-2012 MKZ HEV vehicles may experience reduced electric vehicle operation and increased gasoline engine operation. Do not attempt repairs at this time. Engineering is investigating, monitor OASIS for updates.
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.

If diagnosis leads to only camshaft/camshaft roller follower(s) requiring replacement, replace all of the camshaft roller followers on both banks/cylinder heads with part number 3L3Z-6564-A, not just the faulty roller follower(s). When replacing the camshaft roller followers, refer to Workshop Manual (WSM), Section 303-01.
