What engine is in a F-650 U-Haul?
There isn’t one single engine for the F-650 U-Haul; fleets have used multiple powerplants over the years, with the 6.0-liter Power Stroke diesel being the most common in later years, alongside older trucks that ran a 7.3 Power Stroke diesel or a 6.8-liter V10 gasoline.
The exact engine in a specific unit depends on its production year and configuration. Below is a historical look at the main options and how to verify which engine your truck has.
Engine options across the U-Haul F-650 timeline
Below is a snapshot of the typical engine options that powered Ford F-650s used by U-Haul over different eras.
- 6.0-liter Power Stroke V8 diesel — a common diesel option for mid-2000s to early-2010s Ford heavy-duty trucks, including some F-650s in U-Haul fleets.
- 7.3-liter Power Stroke V8 diesel — an older diesel option used in some earlier Ford heavy-duty applications; it appears in older F-650 units but is less common in newer fleets.
- 6.8-liter Triton V10 gasoline — a gasoline alternative used on some F-650 configurations, particularly in fleets that favored gasoline powertrains.
The exact engine in a specific U-Haul F-650 is determined by the vehicle’s year and configuration; checking the VIN or fleet records will confirm the exact engine for a given unit.
Tips for identifying the engine in your truck
To verify the engine, inspect the engine badge or stamping, review the vehicle’s VIN (which encodes the engine family), or consult U-Haul fleet maintenance records. If you’re researching or evaluating a unit, request the specific build year and engine code when contacting support.
Summary
U-Haul’s Ford F-650 fleet has featured multiple engine options across its production years. The most commonly encountered engine in later fleets is the 6.0L Power Stroke diesel, with older units sometimes using the 7.3L Power Stroke diesel or the 6.8L V10 gasoline. The exact engine depends on the truck’s year and configuration; verify with the VIN or fleet records for a precise answer.
