Where is the active grill shutter located?

Where is the active grill shutter located?

Electronically controlled by an engine control module, the shutter is located between the grille and engine radiator. The shutter automatically opens when the engine needs cooling to maintain the ideal engine operating temperature, and closes when it doesn’t.

What does grille shutter malfunction mean?

The active grille shutter actuator is equipped with a self-diagnosis function. If a malfunction is detected, a signal is transmitted to the ECM and the ECM records the active grille shutter malfunction. The active grille shutter is fully open when the vehicle stops or the ignition switch is turned OFF.

At what speed range is active grille shutter generally closed quizlet?

The ECM operates the shutter to the closed position when all the conditions of the active grille shutter are met: vehicle speed (approximately 19-88 MPH), engine coolant temperature (approximately less than 203°F), engine oil temperature (approximately less than 284°F), CVT fluid temperature (approximately 275°F).

What is a benefit of active grille shutter?

Whilst the primary function of the active grille shutters is to reduce the aerodynamic drag of the car, there are some secondary benefits like improving the warm up time of engine and also retaining engine heat when parked.

Why do I need Active Grille Shutters on my Ram 1500?

SlowRoller Senior Member. The Ram 1500 is the first truck to use an active grille shutter system (similar to the one on Dart), closing airflow through the grille when cooling is not needed. It increases gas mileage by 0.5%, cuts drag roughly 4%, and cuts warm-up time/defrost time. The computer closes the shutters when cooling is not needed.

When do you close the shutters on a Dodge Ram?

The computer closes the shutters when cooling is not needed. Dave Sowers pointed out that the active shutters was normally either fully open or fully closed. When closed, air pressure quickly builds up in front of the slats, deflecting oncoming air over the truck, which has the lowest drag coefficient of any pickup on the market.

Why did I delete the active grille shutter system?

If you put a lower temp thermostat in your truck for performance reasons these shutters will fight you and try to restrict airflow to bring you back to 203*. Also I need to make room for my procharger intercooler so these had to go! Overall my temps have dropped dramatically now and my E-Fan barely kicks on.
