The air filters in a Lexus ES 350 come in two varieties: the engine air filter in the engine bay and the cabin air filter behind the glove box. Each serves a different purpose and location, but both are designed to be accessible for routine replacement.
In most ES 350 models, you’ll find the engine air filter housed in a rectangular black plastic box in the engine compartment, while the cabin air filter sits inside the cabin behind the glove box. The following guide covers how to locate and replace each filter, with notes you’ll want to keep in mind for different model years.
Engine air filter location
To locate and access the engine air filter on an ES 350, follow these steps:
- Park on a level surface, turn off the engine, and let it cool before you start.
- Open the hood and look for a rectangular black plastic housing in the engine bay, typically toward the front passenger side (near the fender and/or wheel well).
- Release the fasteners or clips holding the housing lid in place and lift the lid off.
- Take out the old air filter, noting the orientation of the filter (an arrow on the filter usually points toward the engine).
- Wipe the inside of the housing with a clean rag to remove any dust or debris.
- Insert the new filter with the correct orientation, replace the housing lid, and re-secure the clips or screws.
- Reconnect any intake ducts or hoses that were connected to the housing and close the hood.
Concluding the engine air filter replacement involves ensuring a snug seal of the housing and confirming the intake ducting is properly reconnected so the engine can pull air efficiently during operation.replace intervals vary by environment and driving habits, so consult your owner’s manual for guidance.
Cabin air filter location
To locate and access the cabin air filter behind the glove box, use these steps:
- Park and turn off the vehicle, then open the glove box.
- Remove contents and, if needed, detach the glove box damper or stop arms to allow the glove box to drop down fully.
- Look for a rectangular cabin filter cover mounted behind the glove box and release the tabs or screws to remove the cover.
- Take out the old cabin filter and inspect the filter housing for debris.
- Insert the new cabin filter with the airflow indicator pointing in the correct direction (usually toward the heater core).
- Reattach the filter cover and secure the glove box damper or stops, then close the glove box.
After replacing the cabin filter, ensure the glove box is functioning smoothly and that there are no loose panels. Cabin filter replacements are commonly done during routine maintenance or if occupants notice reduced airflow or odors.
Summary
On a Lexus ES 350, the engine air filter is housed in a rectangular box in the engine bay, typically on the passenger side, and is accessed by unclipping the lid and replacing the filter with the correct orientation. The cabin air filter sits behind the glove box inside the cabin and is accessed by dropping the glove box, removing the filter cover, and installing a new filter. Both filters are designed for straightforward replacement with basic tools, and following the proper orientation ensures optimal filtration and airflow.
