Tools You'll Likely Need:
* Socket wrench set (metric)
* Screwdrivers (Phillips and possibly flathead)
* Possibly a small pry bar or trim tool
* Rags or shop towels
* New IACV (ensure you get the correct one for your engine)
* Electrical contact cleaner (optional, but recommended)
Procedure:
1. Disconnect the Battery: This is crucial to prevent electrical shorts and potential damage. Disconnect the negative (-) terminal first.
2. Locate the IACV: On a 2001 Ford Focus, the IACV is usually located on the throttle body. The throttle body is a part of the intake manifold, often near the air filter box. It's a relatively small valve, often with a single electrical connector.
3. Access the IACV: You may need to remove some air intake components or other parts to get good access to the IACV. This could involve removing parts of the air intake system or disconnecting the air filter housing. Consult your repair manual to see the exact procedure for your specific engine.
4. Disconnect the Electrical Connector: Carefully unplug the electrical connector from the IACV.
5. Remove the IACV: The IACV is typically held in place by screws or bolts. Remove these carefully. Sometimes a small amount of resistance can occur due to the valve's seal against the throttle body; be gentle to avoid damaging the throttle body itself.
6. Clean the Throttle Body (Optional but Recommended): While you have access, clean the throttle body with a throttle body cleaner. This helps ensure smooth operation after the replacement. Follow the cleaner's instructions carefully. Avoid spraying cleaner directly onto any sensors.
7. Install the New IACV: Install the new IACV in the reverse order of removal. Make sure it's seated correctly.
8. Reconnect the Electrical Connector: Securely reconnect the electrical connector to the new IACV.
9. Reassemble: Reinstall any parts you removed to access the IACV.
10. Reconnect the Battery: Reconnect the battery's negative (-) terminal.
Important Considerations:
* Engine Type: The location and accessibility of the IACV can slightly vary depending on the specific engine in your 2001 Ford Focus (Zetec, etc.). Consult your repair manual for diagrams and specific instructions relevant to your engine.
* Torque Specifications: Use the correct torque specifications for all bolts and screws to avoid damaging parts.
* Cleaning: Use the correct throttle body cleaner and follow its instructions carefully.
* Computer Reset: Some vehicles may require a computer reset (disconnecting the battery for a longer period or using a diagnostic scanner) after replacing the IACV to clear any stored codes and allow the computer to relearn the idle parameters.
If you are not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. Incorrect installation can lead to further problems. Always prioritize safety and consult your repair manual for your specific vehicle model and engine.
