Diesel maintenance notes for this vehicle
- Filtration: Robust filtration systems are essential to protect the turbocharger and high-pressure injection components.
- Fuel Integrity: Owners should focus on fuel system integrity and management of diesel exhaust fluid (DEF) if applicable.
- Verification: Because specific engine code details and exact performance metrics can vary, always verify specifications using the vehicle’s door jamb sticker or owner’s manual before performing mechanical work.
Recall, TSB, and manufacturer communication notes
The following information is based on NHTSA research for the 2019 Ford F-350 Pickup. Owners should verify current open recalls by VIN through an authorized dealer.
- Engine Block Heater (Campaign 18V894000): Certain models may have a risk of corrosion in the block heater cable’s splice connector, which could lead to a resistive short and fire risk.
- Seat Recliner Mechanism (Campaign 19V633000): Some driver or passenger manual front seat back recliners may be missing a third pawl, potentially resulting in a loose seat back during a crash.
- Axle Assembly (Campaign 20V576000): Research indicates a recall regarding the power train axle assembly for certain single and dual rear wheel models.
About this vehicle
The 2019 Ford F-350 is a prominent member of the Ford Super Duty series, engineered specifically for high-capacity tasks rather than being adapted from lighter consumer models like the F-150. As a Class 2 or 3 truck, the F-350 is built with specialized chassis components to support significant payloads and heavy towing requirements. This model line also extends into chassis cab configurations for various commercial applications.
This specific vehicle variant is equipped with the Ford Power Stroke V8 diesel engine. The Power Stroke engine family is a cornerstone of the Super Duty lineup, providing the high torque necessary for demanding work environments such as agricultural use, heavy towing, and commercial hauling. Because this is a diesel-powered variant, maintenance requirements differ significantly from gasoline counterparts. Owners often research specialized diesel service intervals, including fuel system integrity and robust filtration systems to protect critical components like the turbocharger.
