The Buick Encore has two air filters you should know about: the engine air filter located in the engine bay and the cabin air filter located behind the glove box. Regular checks and replacements keep the engine breathing clean air and the cabin comfortable for passengers.
Engine air filter location
Overview
In most Buick Encore models, the engine air filter sits in a rectangular plastic housing in the engine bay, typically toward the front-left (driver’s side) area. The housing is connected to the intake duct that leads to the throttle body.
These steps will help you locate and inspect the engine air filter:
- Open the hood and locate the large rectangular plastic air filter housing, usually with a hose running from the front of the grille toward the throttle body.
- Release the retaining clips or screws that secure the housing cover and lift the cover away from the box.
- Remove the old filter and inspect it for excessive dirt, tears, or moisture.
- Carefully place a new filter into the housing with the airflow arrows oriented toward the throttle body, ensuring a snug fit.
- Reattach the housing cover and secure all clips or screws, then reconnect any hoses if you detached them.
Keeping the engine air filter clean helps maintain optimal engine performance and fuel efficiency. Replacement is typically recommended around every 30,000 miles, but dusty or harsh conditions may require more frequent changes. Always check the owner's manual for your exact interval.
Cabin air filter location
Overview
The cabin air filter in the Buick Encore is generally found behind the glove box on the passenger side. Access is gained by dropping or lowering the glove box to reveal a small rectangular filter housing.
How to access and replace the cabin air filter:
- Open the glove box and remove items to create space to work.
- Gently press in the sides of the glove box to release the stops or remove the damper so the box can drop down fully.
- Look for a rectangular cover or door on the back of the glove box area and release the clips or tabs to open the cabin filter housing.
- Take out the old cabin air filter and inspect for dirt or debris.
- Insert the new filter with the arrows pointing toward the HVAC unit (in the direction of airflow into the cabin).
- Reattach the housing cover, snap the glove box back into place, and ensure the glove box closes cleanly.
Regular cabin air filter replacement improves airflow from the HVAC system and reduces odors inside the vehicle. Typical replacement intervals range from 12,000 to 30,000 miles or about once a year, depending on driving conditions. Refer to the owner's manual for the recommended schedule for your model year.
Summary
In the Buick Encore, there are two separate filters to consider: the engine air filter, located in a rectangular housing in the engine bay (usually on the driver’s side), and the cabin air filter, located behind the glove box on the passenger side. Both are designed for easy DIY access with basic tools, though the cabin filter requires dropping the glove box. Regular inspection and timely replacement help maintain engine performance and cabin comfort.
