However, the exact location can vary slightly depending on the year and specific engine configuration. To be absolutely certain, it's best to:
* Consult your owner's manual: This will have a diagram showing the location.
* Use an online repair manual: Sites like Chilton or Haynes offer detailed diagrams and instructions.
* Look up a YouTube video: Search for "[Year] Chevy Avalanche 5.3L oil change" – videos often show the filter's location clearly.
A visual check will always provide the best confirmation before you start working on your vehicle.
