The 1988 S-10 offered three engine options: a 2.5-liter inline-four, a 2.8-liter V6, and, in some configurations, a 4.3-liter V6. Availability depended on trim and cab/bed configuration.
In the 1988 model year, the S-10 continued GM’s approach from the first generation, pairing a basic four-cylinder with more powerful V6 options for buyers who needed extra torque for hauling or highway driving. The exact engine depended on trim level, cab style (standard or extended cab), and the equipment package chosen.
Engine options
The following engines were available in 1988 S-10 pickups:
- 2.5-liter inline-four (I4) — base engine for the line
- 2.8-liter V6 — common V6 option for improved torque
- 4.3-liter V6 — available on higher-trim or specific configurations
Availability varied by trim level, cab configuration, and emissions equipment. The exact combinations determined which engines could be ordered and installed on a given truck.
Summary
For 1988, the Chevy S-10 offered a practical range of powertrains: a base 2.5L inline-four, with optional 2.8L and 4.3L V6 engines for more capability. The engine chosen depended on trim, cab/bed configuration, and the buyer’s needs for efficiency versus towing and payload.
