Safety First:
* Disconnect the negative battery terminal before beginning any work.
* Wear safety glasses and gloves.
* Work in a well-ventilated area.
Tools You'll Likely Need:
* Socket wrench set (metric)
* Wrenches (metric)
* Pliers
* Screwdrivers (Phillips and flathead)
* Jack and jack stands (essential for safe working conditions)
* Possibly a ratchet with extensions
* Shop rags or paper towels
Removal Steps (General Outline):
1. Locate the Smog Pump: The smog pump is usually located near the engine, often on the passenger side. Its a relatively large, cylindrical device with hoses and vacuum lines attached. Consult your repair manual for the exact location on your specific model.
2. Disconnect Hoses and Vacuum Lines: Carefully disconnect all hoses and vacuum lines connected to the smog pump. Take photos or make notes to ensure you reconnect them correctly during reassembly. Labeling the hoses is highly recommended.
3. Disconnect Electrical Connector: There will be an electrical connector supplying power to the smog pump. Carefully disconnect this connector.
4. Remove Mounting Bolts: The smog pump is usually mounted to the engine block or a nearby bracket with bolts. Use the appropriate sockets and wrenches to remove these bolts. You might need to use extensions to reach some bolts.
5. Remove the Pump: Once all bolts are removed, carefully remove the smog pump from its mounting location. It might be a bit heavy, so be prepared.
6. Inspect and Clean: Once removed, inspect the area where the pump was mounted for any debris or leaks. Clean up as needed.
7. Block Off (Optional but Recommended): After removing the pump, you'll need to plug or cap the holes where the hoses and pipes connected. This prevents air leaks and potential issues with the engine's operation. You can use appropriate-sized rubber caps or plugs, available at auto parts stores. Consult a repair manual or seek advice on the best method of blocking off these openings.
Important Considerations:
* Exhaust Manifold: Be aware that the exhaust manifold and other hot engine components are close to the smog pump. Take extra care to avoid burns. Let the engine cool completely before working near it.
* Repair Manual: This is crucial. A repair manual will provide precise diagrams, torque specifications, and other important details specific to your vehicle.
* Emission Laws: Check your local emission regulations before removing the smog pump. In some areas, removing emission control devices is illegal.
This is a general guide. The exact steps may vary slightly depending on your specific vehicle. Always consult a repair manual before attempting this repair. If you're uncomfortable performing this task, it's best to take your vehicle to a qualified mechanic. Improper removal or reassembly can lead to engine damage or emission issues.
