The 2004 Lexus LS430 is a luxury sedan known for its smooth ride, elegant design, and powerful performance. It features a 4.3-litre V8 engine with 290 horsepower, making it a reliable and comfortable vehicle for both city driving and long road trips. However, even the most dependable cars eventually need a new battery, and replacing one yourself can save you time and money. In this guide, I'll walk you through the steps to replace your Lexus LS430 battery with ease.


Tools You'll Need:

Here’s what you need to get started on replacing the battery in your 2004 Lexus LS430:

  • 10mm size socket

  • Ratchet


Recommended Battery:

When choosing a replacement battery for your Lexus LS430, it's important to select the correct size to ensure proper fit and performance. Here’s the recommended battery group size for this vehicle:

Group 24F


How to Replace Your 2004 Lexus LS430 Battery:

1. Locate the Battery: The battery in the 2004 Lexus LS430 is located under the hood on the passenger's side. Make sure the vehicle is turned off before you begin.

2. Disconnect the Negative Cable: Start by disconnecting the negative cable using a 10mm socket. Loosen the bolt and gently pull the cable off the terminal. Set it aside to prevent accidental reconnection.

3. Disconnect the Positive Cable: Using the same 10mm socket, disconnect the positive cable next. Again, ensure it’s placed out of the way.

4. Remove the Battery Hold Down: The battery is secured by a hold-down bracket. Use the 10mm socket to remove the bolt on the bracket, then carefully lift away.

5. Remove the Battery: The battery can now be lifted out of the vehicle. Take care when removing it as car batteries can be heavy.

6. Install the New Battery: Place the new Group 24F battery into the same position under the hood.

7. Reconnect the Hold Down: Reinstall the battery hold down clamp and tighten the bolt with the 10mm socket to keep the battery securely in place.

8. Reconnect the Positive Cable: Now, reconnect the positive cable to the new battery and tighten it with the 10mm socket.

9. Reconnect the Negative Cable: Finally, reconnect the negative cable, tightening it securely.

10. Test the Alternator: Once the battery is installed, it's a good idea to test your alternator to ensure it’s charging the new battery correctly. The alternator should be producing between 13.5 and 14.5 volts, though this can vary by manufacturer.
