SSM 539732025-07-02. Service bulletin. POWER TRAIN; ENGINE. Some 2021-2024 Edge/Nautilus, 2021-2025 Bronco/Bronco Sport/E-Series/Escape/Corsair/Expedition/Navigator/Explorer/Aviator/F-150/F-Super Duty/Mustang/Ranger, and 2022-2025 Maverick vehicles may require an A/C compressor clutch assembly replacement be performed for various concerns. Workshop Manual (WSM), Section 412-00 Removal and Installation has been updated to eliminate the need to remove and install the A/C compressor to change out the A/C Compressor clutch assembly.
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.
SSM 523342024-03-20. Service bulletin. ENGINE AND ENGINE COOLING. Some 2011-2024 Mustang and F-150 vehicles equipped with a 5.0L engine may exhibit a tick tap and/or typewriter 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. The noise in question may be heard on some engines when engine temperatures reach 150°F (65°C) or higher and engine speed is at idle up to approximately 1700 RPM. It can typically be heard at the front wheel well and is often isolated to the transmission bell housing or oil pan area. The typewriter noise tick rate can be faster or slower and is not detrimental to the engine function or durability and has no short or long term effects on the engine. This an operating characteristic of the 5.0L engine and no repairs should be attempted. This information along with an example audio clip has been added to the WSM Section 303-00 Engine System General Information > Diagnosis and Testing > Engine > PPT F > Step F2.
TSB 23-21322023-05-31. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. Some 2018-2023 Mustang vehicles (non-Shelby GT-350) may exhibit various concerns with the active exhaust system. These may include Exhaust Mode Selection Not Available messages, and/or illuminated malfunction indicator lamp (MIL) with diagnostics trouble codes (DTCs) P26C5, P26C6, P26FE, P2BF9, P2BFB, P26C7, P2BF5, P2BF8, P2BFD and/or P2BFA. This may be due to an improperly seated exhaust system. To correct the condition, follow the Service Procedure to diagnose the tailpipe actuator.
