In short, the engine air filter sits in a rectangular housing in the engine bay on the passenger side, while the cabin air filter lives behind the glove box on the passenger side. Variations by year exist, but those are the typical locations across most Equinox models.
The question matters for owners who want to replace filters themselves to keep engine performance and interior air quality at their best. The Equinox uses two distinct filters: one for the engine’s intake and one for the HVAC system that services the cabin. Access points and replacement steps can vary slightly by model year, so consult your owner's manual for your exact configuration.
Engine air filter: location and replacement steps
Follow these steps to locate and replace the engine air filter on most Equinox models. This list lays out a straightforward, general process you can adapt to your year.
- Park on level ground, turn off the engine, and open the hood. Locate the engine air filter housing on the passenger side of the engine bay; it’s a rectangular black plastic box connected to a large intake duct.
- Unclip or unscrew the housing cover. Depending on year, fasteners may be plastic clips, screws, or wing nuts.
- Lift the lid and remove the old filter. Take note of the filter’s orientation and the direction of the airflow arrows.
- Wipe out the inside of the housing with a dry cloth to remove any dust or debris.
- Insert the new filter with the arrows pointing toward the engine, and reseat the housing cover securely.
- Close the hood and start the engine briefly to check for any air leaks around the housing.
Replacing the engine air filter is a quick, inexpensive maintenance task that can improve acceleration, fuel economy, and overall engine performance when done on schedule. Check your owner’s manual for the recommended interval for your specific year and engine configuration.
Cabin air filter: location and replacement steps
Behind the glove box on most Equinox models is the cabin air filter. This list walks you through a typical replacement process, noting that some years may differ slightly in how the glove box is accessed.
- With the engine off, open the passenger-side glove box and carefully release the stops or dampers to allow the box to hang down.
- Look for the cabin filter housing just behind the glove box. It’s usually a rectangular panel with clips or a small cover that you’ll remove to access the filter.
- Remove the cover and pull out the old cabin filter. Pay attention to the filter’s orientation and the direction of airflow on the frame.
- Insert the new filter in the same orientation, ensuring it sits flat and fully seated in the housing.
- Reattach the filter cover, lift the glove box back into place, and ensure the stops/damper are secure.
Replacing the cabin air filter helps maintain HVAC performance and interior air quality, particularly for allergy sufferers or in dusty conditions. Most manufacturers recommend a yearly or every-12,000-15,000-mile replacement, but consult your owner’s manual or a dealer for your exact schedule based on driving conditions.
Tips and reminders
Always work with the engine off and the hood cooled before starting. If you’re unsure about your specific model year’s filter access, refer to the owner’s manual or a trusted repair guide for step-by-step instructions tailored to your Equinox.
Tools and supplies you might need
You’ll typically need only basic tools and a replacement filter. Some models may require a screwdriver or a small pry tool to release fasteners, but many filter housings simply snap open with light finger pressure. Have a flashlight handy to inspect the inside of the housing for debris.
Summary
In most Chevrolet Equinox models, the engine air filter is located in the engine bay on the passenger side inside a rectangular housing, while the cabin air filter is behind the glove box on the passenger side. Replacement is a routine DIY task that helps maintain engine performance and interior air quality. Always verify the exact steps for your model year in the owner’s manual, as access methods can vary slightly across generations.
