* Year: S-10s were produced for many years (1982-2004), and engine technology and specifications changed considerably over that time.
* Engine: Different engines were offered in S-10s (4-cylinder, V6, various displacements). Each engine has its own specific timing requirements.
* Fuel System: Carburetor, TBI (throttle body injection), or MPI (multi-port injection) systems all influence the timing.
To find the correct timing for *your* Chevy S-10, you need to:
1. Identify the year and engine of your truck. This information is usually found on a sticker under the hood or in the glove compartment.
2. Consult your owner's manual. This will provide the specifications for your specific vehicle.
3. Use a timing light. This is the only reliable way to verify the timing setting. Properly setting the timing requires specialized tools and knowledge. If you are not comfortable doing this yourself, consult a qualified mechanic.
Without knowing the specific year, engine, and fuel system of your S-10, it's impossible to give you a precise timing value.
