What engine came in the 89 Chevy truck?
In 1989, Chevrolet's light-duty C/K pickups offered multiple engine options, including a 4.3L V6, 5.0L V8, 5.7L V8, and a 6.2L diesel on heavier-duty models.
In more detail, the exact engine available depended on the model (C or K series, 1500/2500/3500), cab configuration, and whether the truck was geared for workhorse duties. Gasoline engines used throttle-body injection in this era, while the diesel was a mechanical-injection V8. Here is the lineup as it was commonly offered in 1989.
Engine lineup for 1989 Chevy trucks
The following options were available across different trims and chassis, with the 6.2L diesel generally limited to heavier-duty versions.
- 4.3L V6 (262 cubic inches) with throttle-body injection
- 5.0L V8 (305 cubic inches) with throttle-body injection
- 5.7L V8 (350 cubic inches) with throttle-body injection
- 6.2L diesel V8 (common in heavy-duty C/K 2500/3500 models)
The engines were paired with standard or optional transmissions, including manual and automatic options, depending on the engine and trim.
Identifying the engine in your 1989 Chevy truck
To confirm the engine in a specific truck, check the VIN, look for the engine stamping on the driver's side block, and reference Chevrolet service documentation for the exact code. The engine code is typically stamped on the block near the starter, and the door jamb or glovebox label can provide the corresponding options information.
Performance and maintenance notes
Gasoline engines from this era require regular maintenance: timely cooling and fuel-system upkeep, along with ignition and emission-system checks. The 6.2L diesel has different maintenance requirements and uses diesel fuel, with its own routine checks (fuel filters, pump timing, and glow plugs in cold weather). If you’re restoring or buying, verify the service history and the availability of parts for the specific engine in question.
Summary
Overall, the 1989 Chevy C/K lineup offered a mix of gasoline engines—the 4.3L V6, 5.0L V8, and 5.7L V8—and, in heavier-duty models, the 6.2L diesel V8. The exact choice depended on the model, trim, cab/bed configuration, and drivetrain. For a precise determination, consult the vehicle’s VIN and original documentation or a trusted factory reference for that year.
