What size engine is in a Dodge D250?
In short: the D250 did not have a single engine size. Most D250 pickups were powered by a 5.2-liter (318 cubic inch) V8 or a 5.9-liter (360 cubic inch) V8, with diesel options on some heavy‑duty models.
The D250 name refers to the Dodge D-Series line of pickups produced across several decades (roughly the 1960s through the early 1990s). Engine choices changed by year, market, and option packages. This article outlines the typical gasoline engine sizes and the diesel option, and how you can verify the exact engine in a specific truck.
Common gasoline engine sizes offered in the D250
Most D250 trucks used one of Dodge's two popular small-block V8s in that era—the 318 and the 360—before emission controls and model-year changes narrowed the lineup. The exact engine depends on the year and configuration.
- 5.2-liter V8 (318 cubic inches)
- 5.9-liter V8 (360 cubic inches)
These engines were widely used across Dodge's D-Series during their production, though not every D250 had both options; some years used other variants or updated engine families.
Diesel and other powertrain options
In select late‑model D250 trucks, especially those configured for heavier-duty use, a diesel option was offered. The most common diesel installation was a Cummins inline‑six 5.9L turbo diesel in appropriate heavy‑duty configurations, though availability varied by year and market.
- Cummins 6BT 5.9L turbo diesel (in select heavy-duty D-Series models)
Because engine availability shifted over time, the D250 could be equipped with different powertrains depending on the original configuration. For a precise answer about a specific vehicle, check the VIN, engine code stamping, and original documentation.
How to verify the engine size in your D250
To determine the exact engine in a particular D250, use a combination of documentation and on‑engine markings. The steps below help you confirm the size for a specific truck.
- Inspect the engine itself for a stamped displacement, such as 318 or 360, usually on the valve cover or timing cover.
- Check the engine code printed on the engine block or on a plate near the radiator or engine bay; decode it using Dodge’s service manuals or a trusted online VIN/engine code resource.
- Read the original window sticker or build sheet if available; these documents list the engine option chosen at factory.
- Cross-check the VIN with a factory data sheet or a Dodge/DaimlerChrysler database to confirm the engine specification for that VIN.
These steps help ensure you know the exact displacement for a specific D250 rather than assuming based on model year alone.
Summary
The Dodge D250 offered multiple engines over its life. The most common gasoline options were the 5.2L (318) and 5.9L (360) V8, with a diesel option (Cummins 6BT 5.9L) available on select heavy‑duty versions. Engine availability varied by year and market, so verifying via the vehicle’s VIN, engine stamping, and original documentation is essential for an exact specification.
