Where is the secondary air pump located on a 2001 Chevrolet S10?

The secondary air injection (AIR) pump on a 2001 Chevrolet S10 is typically located near the front of the engine, on the passenger side. However, the exact location can vary slightly depending on the engine (4.3L V6 or 2.2L 4-cylinder). It's usually mounted to the engine block or firewall and will be a relatively small, electrically driven pump with air hoses connected.

To be certain, it's best to:

1. Consult your owner's manual: It will have a diagram showing the location of major components.

2. Use a repair manual: A Haynes or Chilton manual specific to your year and engine will provide detailed diagrams and descriptions.

3. Search online for diagrams: A Google image search for "2001 Chevy S10 secondary air pump location [your engine size]" might yield helpful pictures.

Because the location isn't completely standardized, visual confirmation is recommended.
