How many air filters does a 2018 Chevy Malibu have?
The 2018 Chevy Malibu typically uses two air filters: one engine air filter and one cabin air filter.
This article explains the two-filter setup, where to find each filter, and how to replace them when needed, with practical guidance for Malibu owners and DIY enthusiasts.
Two filters in the Malibu: engine and cabin
The Malibu’s filtration system comprises two distinct components that serve different purposes: clean intake air for the engine and clean air for the passenger cabin. This separation helps protect engine performance and maintain interior air quality, especially in dusty or polluted environments.
- Engine air filter
- Cabin air filter
In short, the Malibu relies on these two filters to manage both engine performance and cabin comfort.
Locations and basic replacement concepts
Before attempting any filter work, consult the owner's manual for your specific trim and production date, as locations can vary slightly by model year or region. The engine air filter sits in the engine bay, usually in a rectangular intake box on the front or side of the engine. The cabin air filter is typically accessed from inside the vehicle, most commonly behind the glove box, though some configurations place it under the dashboard or within a side panel. Access often requires removing a panel, door, or screws to reach the filter cartridge.
Engine air filter
The engine air filter protects the intake system from dust and debris and helps maintain engine efficiency. To replace it, you’ll typically open the engine air box, remove the old filter, inspect the box for debris, insert a new OEM or equivalent filter, and reseal the box. Replacement intervals commonly range around 30,000 miles under normal conditions, but driving in dusty conditions or harsh environments may necessitate more frequent changes. Always verify the exact part number and interval in your manual or with a dealer if you’re unsure.
Cabin air filter
The cabin air filter cleans the air entering the passenger compartment through the HVAC system and can affect odor control and airflow. To replace it, you generally access the filter housing behind the glove box, remove the old filter, and insert a new one with the correct orientation. Typical replacement intervals are shorter than the engine filter—often around 15,000–25,000 miles or annually, depending on climate and usage. If you notice reduced airflow or persistent odors, it’s a sign the cabin filter may need replacement.
Maintenance tips for both filters
Regular inspection and timely replacement help maintain performance and air quality inside the Malibu. Here are practical tips to stay on top of filter upkeep:
- Inspect both filters during routine service or at least once a year, especially if you drive in dusty areas.
- Replace engine and cabin filters with OEM or equivalent parts that meet GM specifications.
- Keep a note of any changes in engine performance (for the engine filter) or interior air quality and airflow (for the cabin filter).
Maintaining both filters supports optimal engine performance and a comfortable, clean interior environment.
Summary
For a 2018 Chevy Malibu, you should expect two air filters: one engine air filter and one cabin air filter. Understanding their locations and replacement guidelines helps owners perform timely maintenance and keep the car running smoothly while preserving interior air quality.
