1. Disconnect the battery: Begin by disconnecting the negative terminal of the battery. This will ensure that no power is flowing through the circuit while you are working on it.
2. Locate the idle control valve: The idle control valve is usually located on the engine block, near the throttle body. It is typically a small, cylindrical-shaped component with a plastic connector.
3. Remove the electrical connector: Disconnect the electrical connector from the idle control valve. You may need to use a small screwdriver or pry tool to release the connector.
4. Remove the mounting bolts: There are usually two or three bolts that hold the idle control valve in place. Use a wrench or ratchet to loosen the bolts and remove them.
5. Remove the old idle control valve: Once the bolts are removed, you can carefully remove the old idle control valve from the engine block. Be careful not to drop any of the bolts or gaskets into the engine compartment.
6. Install the new idle control valve: Place the new idle control valve in the same location as the old one. Secure it with the mounting bolts you removed earlier. Tighten the bolts until they are snug.
7. Reconnect the electrical connector: Connect the electrical connector you disconnected earlier to the idle control valve. Make sure the connector is fully seated.
8. Reconnect the battery: Reconnect the negative terminal of the battery.
9. Start the engine: Start the engine and let it idle for a few minutes. Check for any leaks or unusual noises. If everything seems to be in order, turn off the engine and proceed to the next step.
10. Adjust the idle speed: If necessary, adjust the idle speed using the idle adjustment screw, usually located on the throttle body. Consult your vehicle's service manual for the correct idle speed specification.
That's it! You have successfully installed a new idle control valve on your 2000 Infinity QX4.
