1. Preparation:
* Gather Tools: You'll need wrenches (various sizes), sockets, a ratchet, possibly a breaker bar, pliers, and a drain pan to catch any residual fluids. A shop manual is highly recommended.
* Locate the Pump: The smog pump is usually located near the engine's front, often on the passenger side. Identify all the connections: vacuum lines, hoses, and the drive belt.
* Disconnect the Battery: This prevents accidental short circuits.
2. Disconnecting Components:
* Disconnect Vacuum Lines: Carefully disconnect all vacuum lines connected to the pump. Take pictures or make notes to remember their locations for reassembly.
* Disconnect Hoses: Disconnect any hoses leading to the pump's inlet and outlet. Again, note their locations.
* Remove the Drive Belt: Loosen the belt tensioner (usually with a special tool or by carefully prying on it with a wrench – use caution) to remove the belt from the smog pump pulley.
* Disconnect Electrical Connector(s): If there's an electrical connector to the pump (for a thermal switch or other sensor), disconnect it.
3. Removing the Pump:
* Remove Mounting Bolts: Identify and carefully remove all the bolts securing the smog pump to the engine block or other mounting bracket.
* Remove the Pump: Once all the bolts are removed, the pump should come free. It might be somewhat heavy, so be prepared.
4. Post-Removal:
* Plug Vacuum Lines and Hoses: Once the pump is removed, properly seal off the vacuum lines and hoses to prevent leaks and ensure the engine runs correctly. You might need vacuum caps or plugs.
* Reinstall the Drive Belt: Carefully reinstall the drive belt onto the remaining pulleys, ensuring proper tension.
* Reconnect the Battery: Reconnect the battery negative terminal.
Important Considerations:
* Exhaust Manifold: There might be connections between the smog pump and the exhaust manifold. Be careful when working near hot exhaust components.
* Exhaust Gas Recirculation (EGR): Don't confuse the smog pump with the EGR system.
* Legality: Removing a smog pump might be illegal in your area depending on emission regulations. Check your local laws before proceeding.
Disclaimer: This is a general guide. Improper removal can damage your vehicle. Consult a repair manual or a qualified mechanic if you are not comfortable performing this task. Incorrect reassembly could lead to engine damage or other issues.
