1. What Are Active Grille Shutter (AGS) Systems and How Do They Work?

Active Grille Shutter (AGS) systems are ingenious designs intended to elevate a vehicle’s aerodynamic performance while simultaneously accelerating engine warm-up times. These systems strategically govern airflow to the engine compartment via the front grille, thereby reducing drag and optimizing engine temperature.

AGS systems typically comprise:

• Grille Shutter Actuator Assembly
• Radiator Shutter Assembly
• Engine Control Module (ECM)

These systems work harmoniously to manage cooling airflow to the engine by modulating the shutter’s opening and closing, thereby minimizing drag and enhancing fuel efficiency. When the AGS operates flawlessly, it can considerably curtail drag, bolster fuel economy, and expedite the engine’s journey to its ideal operating temperature. However, if the system malfunctions, it can precipitate a cascade of problems, spanning from diminished fuel efficiency to potential engine overheating.
