5. Installation Instructions
Follow these steps to replace the air filter in your EZGO Marathon Gas Golf Cart.
- Prepare the Golf Cart: Ensure the golf cart is parked on a level surface, the engine is off, the key is removed, and the parking brake is engaged. Allow the engine to cool.
- Locate the Air Filter Housing: The air filter housing is typically located near the engine compartment. Consult your golf cart's specific service manual if you have difficulty locating it.
- Remove the Housing Cover: Depending on your model, the air filter housing cover may be secured with clips, screws, or wing nuts. Carefully unfasten these and remove the cover.
- Remove the Old Air Filter: Gently pull out the old air filter element from the housing. Note its orientation for correct installation of the new filter.
- Inspect and Clean the Housing: Examine the air filter housing for any debris, dust, or damage. Use a clean cloth to wipe the inside of the housing. Avoid using compressed air directly into the intake, as this can push debris further into the engine.
- Install the New Air Filter: Insert the new A.A Air Filter Replacement into the housing, ensuring it seats properly and matches the orientation of the old filter. The rubber seals should fit snugly.

- Reattach the Housing Cover: Place the air filter housing cover back into position and secure it with the clips, screws, or wing nuts that were removed earlier. Ensure it is tightly sealed to prevent unfiltered air from entering the engine.
- Test the Golf Cart: Start the golf cart and listen for any unusual noises. Perform a brief test drive to confirm proper operation.
6. Operating Considerations
The air filter functions continuously while the engine is running, cleaning the air before it enters the carburetor or fuel injection system. No specific operational steps are required for the air filter itself beyond proper installation.
7. Maintenance
Regular inspection and replacement of the air filter are essential for optimal engine performance and longevity.
- Inspection: Visually inspect the air filter every 50-100 hours of operation or at least once a year, whichever comes first. Check for excessive dirt, debris, oil saturation, or physical damage.
- Replacement: Replace the air filter every 100-200 hours of operation or annually, or more frequently if operating in dusty or dirty environments. A clogged air filter can significantly reduce engine power and increase fuel consumption.
8. Troubleshooting
If you experience issues after replacing your air filter, consider the following:
- Reduced Engine Performance: If the engine feels sluggish or lacks power, ensure the new air filter is correctly seated and the housing is sealed tightly. An improperly installed filter can allow unfiltered air or restrict airflow.
- Increased Fuel Consumption: A severely clogged air filter can lead to the engine running rich, consuming more fuel. If this occurs shortly after replacement, re-check installation. If the issue persists with a new filter, other engine components may require inspection.
- Unusual Engine Noises: Ensure all clips, screws, or fasteners on the air filter housing are secure. Loose components can vibrate and create noise.
If problems persist, it is recommended to consult a qualified golf cart technician.
