Look for these components to help locate the system:
* Air Pump: This is the electric pump that pushes air into the system. It's usually a relatively large, cylindrical unit, often near the front of the engine compartment, sometimes mounted on the inner fender well.
* Air Injection Pipes/Hoses: These pipes and hoses carry the air from the pump to the exhaust manifold. They are usually made of metal or reinforced rubber and are relatively visible if you look closely near the exhaust manifold.
* Check Valves: These prevent backflow of exhaust gases into the air pump. They're typically small and integrated into the piping.
* Distribution Manifold (Possibly): On some setups, there's a small manifold distributing the air to multiple points on the exhaust manifold.
To effectively locate it:
1. Consult a repair manual specific to your 2000 Chevy S-10 and engine type: This is the most reliable method. The manual will have diagrams and precise locations.
2. Look near the exhaust manifold: The secondary air system is designed to inject air *into* the exhaust to help with catalytic converter efficiency during cold starts. This places its components close to the exhaust system.
3. Visually inspect the engine bay: Look for a relatively large electric pump with hoses and pipes connected to the exhaust.
Keep in mind that the components might be tucked away and difficult to spot without some searching. Using a repair manual will significantly improve your chances of finding them quickly.
