When someone asked if my car had them ('14 MKS) I was ready to say, yes, I keep them right next to the blinker fluid reservoir. Then I googled and found that my car and many others do have them. I even saw a dealer that was selling a '16 MKS which read: "Low miles, twin turbo, heated leather, active grille shutters". Funny. Then I found this:

"Some newer Ford vehicles feature active grille shutters a system that optimizes aerodynamics by using vents to control airflow through the grille to the cooling system and engine compartment.

If air is required to cool the engine, the vents are opened. If no airflow is needed, the vents are shut, contributing to significantly reduced aerodynamic drag.

Mounted ahead of the radiator, the active grille shutters feature motorized horizontal vanes that can rotate 90 to block airflow. Automatically controlled by the cars electronic control unit, the vanes can be rotated into 15 different positions from fully closed to fully open depending on the amount of cooling air required.

When fully closed, the reduction in drag means the active grille shutters can reduce CO2 emissions by 2%.

As an additional benefit, the system keeps the vanes closed as long as possible when starting from cold, so the engine reaches its most efficient operating temperature quicker. This also helps reduce fuel consumption."

You know I will have to see this in action by having someone drive my car while I am in the car in front of it. smile

I remember the 2012 Chevy Cruze Eco having them. Here is a video of them in action:

I appreciate the technology and the intent behind it, but I will be deactivating my Fiesta's grille shutters before summertime. The thing runs hot enough as it is. Most early 1.0 Ecoboost failures that I've read about seem to be due to some kind of overheating related to broken plastic parts in the cooling system. I can live with the 2% emission sincrease, and loss of 0.2 MPG on the highway.

We really only ever replace those on vehicles that have been in accidents.

So what's wrong with a sheet of cardboard with a flap and a string?


If you want the job done right......do it yourself.

The EPA wants that string tied into the ECU. If you can figure out how to wire it in, then it should work.

You joke but the truckers in the winter will put the plastic..thing.. over the front grill to block the cold air.. seems to be the same effect?

Yeah, but think about all the cars where it is broken, and the Owner's have no idea that it's broken.

Personally I would have no long term confidence in a cheap piece of plastic on this part of the car.

Another electronic thing to break right after the warranty is over, no thanks.

the 2014+ Cherokee with the 2.4 has these.

IIRC when they break its around 600-800$ to fix

If you drive around 12000 miles per year

I think that works out to about 5$ in gas.

Heavy trucks have had these for decades. They opened and closed mechanically by a separate thermostat. In the winter they rarely open because of the large cooling systems. I had a vinyl covering that I zipped open or closed depending on the outside temperature. On a really cold day and pulling a light load, they would be zipped up or the engine wouldnt get hot enough to keep the cab warm.

My Sierra has them and I wish it didn't. They make fitting a light bar behind the grille impossible and simply removing them throws a CEL.

On a previous 2017 Continental, when looking close through the grill, I could see the shutters. Look close and you can probably see them. They run horizontally.
