The 1990 Dodge Dakota could be equipped with one of three engines: a 2.5-liter inline-4, a 3.9-liter Magnum V6, or a 5.2-liter Magnum V8. Depending on trim, cab configuration, and options, the exact engine in a given truck varied.
Engine options for the 1990 Dakota
Below are the engines that were commonly offered on the 1990 Dakota. Availability depended on trim level and option packages.
- 2.5-liter inline-4
- 3.9-liter Magnum V6
- 5.2-liter Magnum V8
The mix of these engines covered the Dakota's base, mid-range, and higher-end configurations, from economical daily driving to stronger towing performance.
2.5-liter inline-4
The 2.5-liter inline-4 was the entry option in the Dakota lineup, designed for fuel efficiency and city-to-suburban use. It delivered modest power but kept running costs lower than the V6 or V8 options. Transmission choices typically included a manual or an automatic, depending on the build.
3.9-liter Magnum V6
The 3.9-liter Magnum V6 offered a balance of performance and payload capacity, making it the popular middle option for buyers who wanted a mix of everyday reliability and better torque for light towing or hauling. It was commonly paired with a smooth automatic or a manual transmission.
5.2-liter Magnum V8
The 5.2-liter Magnum V8 provided the most power in the 1990 Dakota lineup, yielding stronger acceleration and towing performance for customers who required heavier-duty capabilities. This engine was typically paired with a more robust transmission option to handle the extra torque.
Verifying the exact engine on a given truck
Because production and option availability could vary by region, trim, and build date, the only way to confirm the exact engine in a specific 1990 Dakota is to check the vehicle’s VIN and build sheet, or inspect the engine stamp and references under the hood. When shopping, ask for the engine code from the door sticker or the original window sticker.
For buyers or restorers, that due diligence helps ensure you’re matching the right power plant to the specific truck’s era and configuration.
Summary
The 1990 Dodge Dakota offered three engines across its first-generation lineup: a 2.5-liter inline-4, a 3.9-liter Magnum V6, and a 5.2-liter Magnum V8. Availability varied by trim and configuration, and buyers could confirm the exact engine through VIN/build documents or the engine code on the block. The choice ranged from economical daily driving to stronger towing performance, reflecting Dakota’s role as a versatile midsize pickup at the close of the decade.
