The 2019 Nissan Pathfinder has two air filters you may need to replace: the engine air filter and the cabin air filter. The engine air filter sits in a rectangular housing in the engine bay, typically on the passenger side toward the front. The cabin air filter is located behind the glove box on the passenger side and is accessed by removing a cover inside the dash.
Engine air filter location and replacement basics
Tools and supplies you’ll likely use before tackling the engine air filter include a replacement filter and basic hand tools to release the housing clips. This list covers the steps to locate and replace the engine air filter in the Pathfinder’s engine bay.
- Park on a level surface, apply the parking brake, and turn off the engine. Open the hood and locate the engine air filter housing, a rectangular black plastic box on the passenger side of the engine bay near the front, connected to the intake duct.
- Unclip or unscrew the housing cover. Depending on your trim, the lid may be secured with metal clips, plastic latches, or small screws. Release or remove them carefully.
- Lift the cover and remove the old filter. Inspect for excessive dirt or damage; replace if it is clogged or if you can’t see light through it when held up to the sun.
- Install a new filter with the correct orientation. Most Nissan filters have an airflow arrow; ensure it points toward the engine as indicated on the filter.
- Re-seat the filter in the housing, then reattach the cover and secure all clips or fasteners. Reconnect any intake hoses that were moved.
- Close the hood and start the engine to check for normal operation and no whistling from a loose fit.
Maintenance note: Engine air filter replacement intervals vary by environment but are commonly checked every 15,000 miles and replaced as needed. Check the owner's manual for the exact recommendation for your vehicle and driving conditions.
Cabin air filter location and replacement basics
Tools and supplies for the cabin air filter replacement are typically a replacement cabin filter and a small screwdriver or trim tool if needed to release the access panel. This list explains how to access and replace the cabin filter behind the glove box.
- With the vehicle parked, open the glove box and remove its contents; on many models you’ll need to lower a damper or tilt the box to access the filter housing.
- Gently press in the sides of the glove box to release the stops, then lower the glove box to expose the filter access panel on the right side of the opening.
- Remove the cabin air filter cover and slide out the used filter. Inspect for heavy dirt or damage and replace with a new filter, noting the arrow on the filter indicating airflow direction.
- Insert the new filter, reattach the cover, and reinstall the glove box by securing the damper or stops and snapping the box back into place.
- Close the glove box and run the HVAC for a few minutes to ensure smooth airflow from the vents.
Cabin air filter replacement intervals typically range from 12,000 to 24,000 miles depending on environment and usage; consult the owner's manual for exact guidance for your vehicle and locale.
Summary
In the 2019 Nissan Pathfinder, there are two air filters: the engine air filter in the engine bay (typically on the passenger side toward the front) and the cabin air filter behind the glove box on the passenger side. The engine filter protects the engine by cleaning incoming air, while the cabin filter helps maintain interior air quality. Replacement steps involve opening the respective housings, removing the old filter, inserting a new one with correct orientation, and reassembling. For precise intervals and locations on your trim, refer to the owner's manual or Nissan service documentation.
What are three symptoms of a clogged cabin air filter?
