5. Operation

The active grille shutter system is an integral part of modern vehicle design, primarily aimed at improving fuel efficiency and reducing emissions. The system operates automatically, controlled by the vehicle's engine control unit (ECU).

• Engine Warm-up: Upon cold startup, the shutters typically remain closed to help the engine reach its optimal operating temperature more quickly. This also assists in bringing the catalytic converter to operating temperature faster, reducing cold-start emissions.
• Aerodynamics: At stable cruising speeds, the shutters may close to improve the vehicle's aerodynamics by reducing drag. This contributes to better fuel economy.
• Cooling: When the engine requires additional cooling (e.g., during heavy load, high temperatures, or low speeds), the shutters will open to allow maximum airflow to the radiator.
• Heater/Defroster Function: The system also helps improve the warm-up time for the vehicle's heater and defroster functions.

The operation is fully automatic and does not require manual intervention from the driver.

6. Maintenance

The Dorman 601-325 Radiator Shutter Assembly is designed for durability and typically requires minimal maintenance. However, periodic inspection can help ensure its longevity and proper function.

• Visual Inspection: Periodically inspect the shutter blades and linkage for any signs of damage, cracks, or obstructions (e.g., debris, leaves).
• Cleanliness: Keep the area around the grille and radiator free from excessive dirt and debris, which could impede shutter movement.
• Functionality Check: If possible, observe the shutters opening and closing during vehicle operation (e.g., during cold start and after the engine warms up) to confirm they are moving freely.

7. Troubleshooting

If you experience issues with your active grille shutter system after installing the Dorman 601-325 assembly, consider the following common troubleshooting steps:

• Check Engine Light (CEL): If a Check Engine Light illuminates related to the active grille shutter, use an OBD-II scanner to retrieve diagnostic trouble codes (DTCs). These codes can pinpoint the specific issue.
• Shutter Not Moving:
  • Verify the electrical connector is securely attached and free from corrosion.
  • Inspect the wiring harness for any visible damage or breaks.
  • Check for any physical obstructions preventing the shutters from moving.
  • Ensure the motor (if separate from the assembly) is functioning correctly. Dorman offers assemblies with and without motors; if your original motor was reused, it might be the point of failure.
• Unusual Noises: Grinding or clicking noises could indicate a mechanical issue with the shutter linkage or motor. Inspect for broken or worn components.
• Fitment Issues: Double-check that the part number 601-325 is correct for your specific vehicle year, make, and model (Dodge Dart 2013-2016). Incorrect fitment can lead to operational problems.

If troubleshooting does not resolve the issue, it is recommended to consult a professional automotive technician.
