The 2020 GMC Canyon has two air filters you may need to service: the engine air filter located in the engine bay, and the cabin air filter behind the glove box. This article explains exactly where to find each filter and how to replace them. The goal is to help you perform a quick, safe filter change to maintain engine performance and interior air quality.
Engine air filter location
The engine air filter is housed in a rectangular plastic box in the engine bay, on the driver's side toward the front of the vehicle. It is connected to an intake duct that leads to the throttle body. Access is gained by releasing the clips or fasteners that hold the box lid in place, then lifting the lid to expose the filter.
To replace the engine air filter, follow these steps:
- Open the hood and locate the rectangular engine air box on the driver’s side of the engine bay.
- Release the clips or fasteners securing the lid and lift the lid off the box.
- Remove the old filter and check its condition; note the filter’s airflow orientation (arrow direction).
- Insert the new filter with the correct orientation and reseat the box lid, ensuring a proper seal.
- Reconnect any intake ducting and close the hood; run the engine briefly to confirm there are no odd sounds or leaks.
Replacing the engine air filter is a routine maintenance task that typically needs attention every 15,000–30,000 miles, depending on driving conditions. A properly seated filter helps ensure optimal airflow and engine efficiency.
Cabin air filter location
The cabin air filter is located behind the glove box on the passenger side of the vehicle. Access is gained by removing the glove box or opening a panel behind it and sliding out the old filter. This filter helps clean the air that enters the passenger compartment through the HVAC system.
To replace the cabin air filter, follow these steps:
- Open the glove box and empty its contents; if needed, gently detach the glove box stopper or damper to allow full access.
- Support or lower the glove box to expose the cabin filter cover behind it.
- Release the cover fasteners or tabs and remove the cover to reveal the used filter.
- Remove the old filter and insert the new one, making sure the airflow arrows point in the correct direction (usually toward the HVAC vents).
- Reinstall the cover, raise the glove box back into place, and ensure it is secured before closing the passenger door.
Cabin air filter replacement is generally recommended every 15,000–25,000 miles, or sooner in dusty or heavily polluted environments, to maintain the HVAC efficiency and interior air quality.
Summary
For the 2020 GMC Canyon, there are two filters to consider: the engine air filter in the engine bay and the cabin air filter behind the glove box. The engine filter sits in a rectangular box on the driver’s side front of the engine, with access by unclipping the lid. The cabin filter sits behind the glove box on the passenger side, accessed by dropping the glove box and removing the filter cover. Regular replacement helps protect engine performance and ensure clean air inside the cabin.
