Active Grill Shutter

[Tacoscott24]

Has anyone noticed their grill shutters move ? anytime I’ve checked mine they have always been open. I don’t really understand what the purpose of the shutter assembly is for. I had the service campaign done to replace the shutter assembly and harness due to corrosion. Any insight would be much appreciated.

Aerodynamic efficiency and thermal management. When closed the shutters prevent airflow from entering the engine bay. Thermal management is one of the key reasons you can get almost 300hp from a 2.4L Turbocharged motor on 87 octane. Finally, emissions and fuel economy are also in play.

After having to replace mine, all I can say is that your entire dash will light up if you have a problem with it.

Yup, you don't notice them until they break That was an annoying 2 months I never wish to revisit.

Why would you notice them move? They're not gonna move while the truck is stopped.

The reason I said that is some manufacturers use them to help the truck reach operating temp faster. My dodge ram remains closed until the truck is close to operating temp regardless of whether you are moving or sitting idling in park
