However, the *exact* location can vary slightly depending on the specific engine (e.g., 4.8L, 5.3L, or 6.0L). To be certain, you should:
* Consult your owner's manual: This is the best resource for precise location information specific to your Avalanche's engine.
* Use a repair manual: A Haynes or Chilton manual for your vehicle will provide diagrams showing the sensor's location.
* Look at online diagrams: Search online for "2004 Chevrolet Avalanche IAT sensor location [your engine size]" and you might find helpful images or forum discussions.
Because of the variability in exact location, it's highly recommended to use one of the above methods to locate it precisely rather than relying solely on a general description. Improper handling of the intake system could damage other parts.
