See Engine Compartment Overview for the location of the engine air cleaner/filter.

Notice: If you spray water into the engine air cleaner/filter intake and water enters the engine air cleaner/filter housing, you could damage your vehicle's engine. The repairs would not be covered by your warranty. Do not spray water into the engine air cleaner/filter intake and/or housing.

If you are cleaning the vehicle with the hood open, take care not to spray water directly near the filter opening of the air cleaner, as shown in the illustration, as this could damage the vehicle's engine.

When to Inspect the Engine Air Cleaner/Filter

Inspect the air cleaner/filter at the Maintenance II intervals and replace them at the first oil change after each 50,000 mile (80 000 km) interval. See Scheduled Maintenance for more information. If you are driving in dusty/dirty conditions, inspect the filter at each engine oil change.

How to Inspect the Engine Air Cleaner/Filter

To inspect the air cleaner/filter, remove the filter from the vehicle and lightly shake the filter to release loose dust and dirt. If the filter remains caked with dirt, a new filter is required.

To inspect or replace the engine air cleaner/filter:

6.2 L LS3 Engine





6.2 L LS9 Engine shown, 7.0 L LS7 Engine similar




1. Remove the screws holding the air cleaner assembly.
2. Pull the air cleaner assembly back to gain access to the filter element.



3. Remove the screws holding the filter element in place.
4. Inspect or replace the filter. See Maintenance Replacement Parts.
5. Reverse Steps 1 and 3 to replace the air cleaner/filter cover.

Caution: Operating the engine with the air cleaner/filter off can cause you or others to be burned. The air cleaner not only cleans the air; it helps to stop flames if the engine backfires. If it is not there and the engine backfires, you could be burned. Do not drive with it off, and be careful working on the engine with the air cleaner/filter off.

Notice: If the air cleaner/filter is off, a backfire can cause a damaging engine fire. And, dirt can easily get into the engine, which will damage it. Always have the air cleaner/filter in place when you are driving.
