The air filter in a Chevy Equinox is housed inside a rectangular plastic air box in the engine bay, and you access it by removing the lid.
Because the Equinox has undergone several redesigns across generations, the exact spot can shift slightly depending on the year and engine. In general, the air box sits in the engine bay and is connected to a large intake hose that leads from the grille area toward the throttle body. Use these cues to identify the housing on your specific model, and consult the manual or a dealer if you’re unsure.
Where the air filter is located
The following outlines the most common placements and ways to identify the air box across Equinox generations.
- Look for a rectangular black plastic air box in the engine bay that’s connected to a large-diameter intake hose running from the grille toward the engine. The box itself is the air filter housing.
- On most Equinox models, the box sits on the passenger side of the engine bay near the front. Some 2018–2023 models place the box a bit toward the center, but it remains near the intake hose.
- The lid of the air box is typically held on by plastic clips or a couple of screws; removing the lid reveals the paper air filter inside.
Identifying the air box by following the large intake hose from the grille toward the engine can help you locate the filter quickly, regardless of exact side or orientation.
How to replace the air filter
Here are the general steps to replace the engine air filter on most Equinox generations. A few years or engines may use slightly different fasteners, but the process is the same in principle.
- With the engine off and cooled, locate the air box by tracing the large intake hose from the grille toward the engine.
- Release the clips or unfasten the screws securing the air box lid, then lift the lid away from the box.
- Remove the old filter, noting its orientation, and inspect the inside of the box for any debris.
- Wipe the interior of the box if needed, then insert the new filter in the same orientation as the old one.
- Reposition the lid and secure all clips or screws to ensure a tight seal.
- Reconnect any hoses or clamps you may have moved, start the engine, and listen for signs of a leak around the air box.
Replacing a dirty or clogged air filter can improve airflow, engine efficiency, and overall performance, especially in dusty conditions or high-mileage scenarios.
Notes for model-year specifics
For exact steps and the precise layout for your year and engine (for example, 1.5L turbo vs. 2.0L turbo), consult the owner’s manual or a dealership service bulletin. Always use the air filter size and type recommended by GM for your specific Equinox.
Summary
The Chevy Equinox’s air filter is housed in a rectangular air box in the engine bay, with the general approach of following the large intake hose from the grille to locate the box. While the exact location can vary by generation and engine, the lid is usually held by clips or screws, and replacing the filter is a straightforward process that helps maintain engine performance and efficiency.
