# Service bulletin TSB\-20\-2105

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.

- Type: Service bulletin
- NHTSA id: 10174401
- Published by NHTSA: 2020\-05\-05
- Manufacturer's number: TSB\-20\-2105
- Manufacturer's date: 2020\-04\-01
- NHTSA component: FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING

## NHTSA's summary

Some 2017\-2019 F\-Super Duty chassis cab vehicles equipped with a 6.7L engine and an aft of axle fuel tank operating in dusty conditions may exhibit a crank/no start concern with the fuel level showing over 1/4 tank full or the fuel gauge only registers up to 1/2 tank after filling with fuel. For vehicles equipped with an auxiliary fuel delivery source, the customer may also experience the inability to deliver fuel using this equipment. This may be due to dirt being trapped around the dust cap on the front or rear rollover valve \(ROV\) preventing "make\-up air" from entering the fuel tank. To correct the condition, follow the Service Procedure steps to replace the fuel tank and possibly also the fuel pump/sender unit.

Some 2019\-2026 F\-Super Duty vehicles equipped with a 6.7L engine may require various repairs and/or maintenance to the fuel system where quick release couplings are utilized, such as the secondary fuel filter. The Workshop Manual \(WSM\), Section 310\-00 \> General Procedures \> Quick Release Coupling has been updated to include videos and instructions of proper disconnect/connect steps involving the Type 27 quick release couplings.

- [SSM 52335](/bulletins/10251952.md), 2024-03-20, 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\-2248](/bulletins/10251453.md), 2024-03-07, 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 51691](/bulletins/10237789.md), 2023-06-16, 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.
