The 2002 S-10 could come with either a 2.2-liter inline-four or a 4.3-liter V6.
In 2002, engine choice depended on trim, cab configuration, and drivetrain. This article details the two engines, their typical power outputs, and how they were paired with transmissions across the 2002 S-10 lineup, including the Chevrolet S-10 and its GMC Sonoma counterpart.
Engine options in the 2002 S-10
Below are the two powerplants that most 2002 S-10 buyers encountered. The goal is to outline what you’d find under the hood across common trims and configurations.
- 2.2L inline-four (gasoline) — about 120 horsepower and around 130 lb-ft of torque; commonly paired with a 5-speed manual or a 4-speed automatic transmission.
- 4.3L V6 (Vortec 4300) — about 190–195 horsepower and 260–285 lb-ft of torque; offered with a 4-speed automatic or, in some trims, a 5-speed manual.
The two engines covered the vast majority of the S-10 and Sonoma lineup, including 2WD and 4WD configurations.
Performance and transmission pairings
Understanding how these engines were paired with transmissions helps explain real-world performance and available configurations. Here’s how the two powertrains commonly paired with gearboxes in 2002 models.
2.2L inline-four details
The 2.2L engine delivered modest power suitable for daily driving and light-duty work. It typically offered a 5-speed manual transmission as standard in base configurations, with a 4-speed automatic option available on higher trims or as an upgrade. Torque was sufficient for basic hauling and city driving, while fuel economy was the primary appeal of this engine choice.
4.3L V6 details
The 4.3L V6 provided a substantial increase in grunt, making it the preferred choice for heavier loads and tougher road conditions. It was commonly paired with a 4-speed automatic transmission, and some configurations offered a 5-speed manual. This powerplant improved both acceleration and towing capacity compared with the 2.2L option, at the cost of lower fuel economy.
Availability of each engine varied by trim level, cab setup (regular cab vs. extended cab), and whether the truck was configured for 2WD or 4WD. The Chevrolet S-10 and its GMC Sonoma counterpart shared these engine options, with regional and dealer variations possible.
Summary
For the 2002 S-10, buyers could choose between a 2.2-liter inline-four or a 4.3-liter V6, with transmission options ranging from 5-speed manuals to 4-speed automatics depending on the exact configuration. The two engines covered the spectrum from basic daily use to more capable all-purpose pickups, with the V6 offering notably stronger performance for heavier loads and tougher terrain.
