The Chevrolet Equinox is a smart choice for budget-friendly SUV buyers. It’s dependable, fuel-efficient, and practical for daily commutes, road trips, and all-weather driving.
If you own a 2018 - 2023 Chevy Equinox with high mileage, regular maintenance is key to keeping it running smoothly. One of the most important yet simple maintenance tasks is replacing the engine air filter. A clean air filter helps maintain fuel efficiency, improves acceleration, and extends the life of the engine.
With Haynes Manuals, you’ll learn how to change the 2018 - 2022 Chevy Equinox cabin air filter. Our manuals also cover key high-mileage car care tips for the engine and cabin, keeping you and anyone riding with you safe and comfortable for the ride ahead.
Why the Engine Air Filter Matters
The engine air filter plays a big role in protecting your engine from dirt, dust, and debris. Over time, it gets clogged, making the engine work harder and reducing performance. A clean filter improves fuel efficiency and engine life while reducing emissions.
If you notice sluggish acceleration or decreased fuel economy, it may be time for a replacement. Chevrolet recommends replacing the engine air filter every 15,000 to 30,000 miles—depending on driving conditions.
When it comes to a high-mileage vehicle, ignoring basic maintenance tasks could lead to more expensive engine repairs later on a scenario that Haynes Chevrolet Equinox 2018-2022 Repair Manual can help you avoid by providing detailed instructions to complete these jobs yourself.
How to Change the Engine Air Filter in a 2018 - 2022 Chevy Equinox
Although changing the engine air filter is straightforward, skipping over important details can lead to confusion or mistakes. This is where Haynes Manuals make all the difference. Our manuals guide you through the precise steps required to ensure the job is done right. For high-mileage vehicles in particular, ensuring a proper filter fit is critical for long-term performance.
High-Mileage Engine Care Tips for a 2018 & 2022 Chevy Equinox
- Keep Up with Oil Changes
High-mileage engines like the Chevy Equinox need regular oil changes to stay in good condition. Synthetic or high-mileage oil helps reduce wear and keeps engine parts lubricated. Change the oil every 5,000 to 7,500 miles.
Frequent short trips or extreme temperatures may require more frequent changes. Check the oil level regularly and look for signs of contamination. Clean oil helps prevent engine damage and extends the life of your Chevy Equinox.
- Clean the Fuel System
A clean fuel system improves engine performance and fuel efficiency. With continued use, carbon buildup can clog fuel injectors and intake valves. Using a fuel system cleaner every few thousand miles helps remove deposits. This allows fuel to flow smoothly and improves combustion.
Consider adding a cleaner before Equinox long drives or when refueling. Regular maintenance keeps your engine running smoothly and helps maximize gas mileage. This makes daily driving more efficient.
- Check the Spark Plugs and Ignition Coils
Faulty spark plugs and ignition coils can cause engine misfires and poor fuel economy. Additionally, worn spark plugs reduce acceleration and make the engine run rough. Replacing them at 100,000 miles improves combustion and guarantees a smoother ride.
If you notice difficulty starting the engine, sluggish performance, or increased fuel consumption, inspect the ignition system. New spark plugs and properly functioning coils help maintain engine efficiency and keep your Equinox running strong. For high-mileage vehicles, using your Haynes manual can help you identify when the spark plugs need replacement—and show you exactly how to replace them yourself.
- Maintain the Cooling System
A well-maintained cooling system can prevent engine overheating and keep performance steady. As miles add up, coolant breaks down and loses effectiveness. Flushing and replacing it every 50,000 miles helps regulate engine temperature.
Check the radiator, hoses, and water pump for leaks or cracks. A properly working thermostat and coolant system is what you need to prevent costly repairs. Refer to your owners manual or Haynes Chevrolet Equinox 2018-2022 Repair Manual to verify the correct coolant is used on the vehicle.
- Inspect the 2018-2022 Chevy Equinox Hood Hinge
The hood hinge allows for smooth opening and closing of the hood, but over time, it can rust or become stiff. Apply lubricant to the hinge points to prevent wear and make it easier to open and close the hood. Avoid using the wrong lubricant, such as WD-40, which is not ideal for long-term lubrication. For more information, refer to Chapter 1, Section 20 on your Haynes Chevrolet Equinox 2018-2022 Repair Manual.
Cabin Care Tips for a High-Mileage Chevy Equinox
- Replace the Cabin Air Filter
It's important to note that the engine air filter and the cabin air filter are two completely separate components located in different areas of your vehicle.
- The engine air filter is responsible for keeping dirt and debris out of your engine, ensuring optimal performance and fuel efficiency.
- The cabin air filter, on the other hand, filters the air inside your car’s interior, improving air quality for passengers.
Since these filters serve different purposes and are found in different locations, be sure to follow the correct steps for the specific filter you’re replacing.
A clean cabin air filter improves airflow and removes dust, pollen, and pollutants from entering the interior. For the 2018 - 2022 Chevy Equinox cabin air filter change, follow these steps:
- Locate the filter behind the glove box.
- Unclip and remove the filter cover.
- Slide out the old filter and insert a new one in the same direction.
- Reattach the cover and close the glove box.
Keep in mind that these are just the basic steps. For a more in-depth guide to replacing the cabin air filter of your Chevy Equinox, it’s best to reference our Chevrolet Equinox Service & Repair Manuals.
- Keep the Interior Clean
Regular cleaning helps maintain your Equinox’s interior and protects surfaces from damage. Vacuum the seats, carpets, and floor mats to remove dirt and debris. Wipe down surfaces with a microfiber cloth to prevent dust buildup.
Use a UV protectant on the dashboard and door panels to reduce fading and cracking. Keep a small trash bag in the car for convenience.
- Check the HVAC System
A properly functioning Equinox HVAC system keeps your vehicle comfortable in all seasons. Inspect the air conditioning and heating for weak airflow or unusual noises.
Routine maintenance on the HVAC system should be performed with the help of a Haynes Manual. If the AC isn’t cooling effectively, check the refrigerant levels or clean the vents. Change the cabin air filter regularly to improve air circulation. Test the heater in colder months to make sure it warms up quickly. A well-maintained HVAC system enhances comfort during daily drives and long road trips. For more information, refer to Chapter 1, Section 20 on your Haynes Chevrolet Equinox 2018-2022 Repair Manual.
- Monitor for Unusual Smells or Sounds
Strange smells or noises inside your Equinox can indicate potential issues. A musty odor may mean mold growth in the AC system. Running the defroster regularly helps dry excess moisture and prevent buildup.
Don’t overlook these issues! If you notice rattling sounds, check for loose trim pieces or worn-out door seals. A burning smell could signal an overheating component. Identifying and addressing these signs early can prevent bigger problems and keep your vehicle running smoothly. Refer to your Haynes Manual for guidance on diagnosing the source of the problem and how to handle repairs.
