The air filter is inside the rectangular air-filter housing on the passenger side of the engine bay, with a large hose running to the throttle body. This is the short answer.
For 2007 Liberty models, which could use a 2.4L four-cylinder or a 3.7L V6, the air box sits on the passenger side of the engine compartment. Access the filter by releasing the housing lid’s clips or screws, lifting the lid, and replacing the filter with the correct orientation.
Location and access
The air filter housing is a rectangular black plastic box on the passenger side of the engine bay, typically near the fender and ahead of the battery depending on engine layout. The large intake hose connects the housing to the throttle body.
How to replace the air filter
Follow these steps to access and install a new air filter. Make sure the engine is cool and the work area is clean before starting.
- Open the hood and locate the rectangular air-filter housing on the passenger side of the engine bay. The lid is secured with clips or small screws.
- Release the clips or unscrew the fasteners and lift the lid to expose the filter.
- Remove the old filter and inspect the housing for debris or signs of wear. Clean gently if needed.
- Install a new filter in the correct orientation (arrow on the filter generally points toward the throttle body or rear of the engine).
- Re-seat the lid and secure the clips or screws, ensuring a tight seal against unfiltered air leaks.
Conclusion: After replacing, verify the air box is properly closed and secure. Replacing the air filter at the manufacturer-recommended interval helps maintain performance and fuel efficiency. In dusty conditions, check and replace more frequently.
Maintenance tips
Keep the area around the air intake clean, avoid spilling fluids near the air box, and replace the filter per the owner's manual or sooner if you notice decreased performance or unusual engine noise.
