2015 vw Jetta shutters went out. $2000 later they are fixed. How much fuel mileage did it save me over the life of the vehicle??? Not $2000 I’m willing to bet. BS!!!!!!
It may sound good on paper but in real life, the little time it saves to warm up and fuel savings are not worth the complexity and cost of these devises when they go south.
@@mouselt1 you are correct. Until you go spend a year in norway where they even install aftermarket electric coolant heaters that warm up the coolant even when the engine is shut. I second you, if the climate not freezing cold. But these devices can reduce the coefficient of Drag by as much as 0.2. which is significant for fuel savings.
Great explanation. However it is just one more crap thing that can and will go bad and cost people money to get repaired. Every time we turn around something else is added that can and will break and cost money to fix. What ever happened to the term (KISS) keep it simple stupid. Less crap on the car that can break the less it will cost to operate.
No. It s the opposite. Drag increases when in enters the inner radiator area and creates a heavy turbulence which pushes the car rearward. When the active flap is closed the air flow is directed to the hood/bonnet and the bottom bumper lip, increasing downforce and reduducing drag. The closed flap acts like a nose. But when open acts like a mouth.
@@hanynowsky Kind of. When open, there is indeed all kinds of turbulence due to the resistance of everything in the engine compartment. When closed, the shutters simply redirect that airflow over the top of the streamlined body of the vehicle, thus reducing drag.
I just replied to another responder. Here is an easy way to understand this: Consider two rivers. One goes straight, but with a lot of boulders and large rocks. The other makes an S-curve but has no obstructions. Which do you think will more easily let the water pass through? That's right, hands down it would be the second one. The reason why is not only does the first one have SEVERAL "walls", but the turbulence from all the various points of deflected water interact with each other causing even further drag. Hope this helps. 🙂
P059F code 2019 Nissan Altima. Shutters were halfway open when parked. After start up, they fully cycled open & close several times, then remained fully open. Hot day and the engine was already warm. For what it's worth, had the same code about a year ago. Disconnected and reconnected electrical harness. Terminals were shiny new, no obstruction no damage. Code went away on its own. When it came back recently, I assumed it was the same issue and did not check it for a couple weeks. When I finally checked it, I found half a styrofoam cup holding the shutters open. Any ideas?
@@800game No. The gears that moved the shutters were stripped, so the position sensor knew it was not operating correctly. Replaced the shutters and problem SOLVED!
@@800game Thought I answered this. Sorry for the delay. I ended up having to replace the shutter as the gears to the motor were stripped. The code went away and has not returned! 😀
Seems like this is common point of failure on the 2019 Altima. I'm currently dealing with it. Several similar posts on various forums for the 2019 model.
@@coomercove Not sure why, but NOW my previous answer appears. Last comment, it did not show up. Hmmm. Anyway, what you say makes sense as mine also failed at low miles/age which surprised me. No doubt there's some sort of design flaw.
My gauge is right below the H is that normal but then the shutters open and comes down I’ve never had it overheat , or the warning come up or the check engine So is that normal?
@@seatime674 I’m sure it helps to a degree. But nothing I could tell just by watching the temps. Since then I’ve added a 180 stat and and tune to turn the fans on sooner.
@@dkrum5854 that’s a whole other problem. Nothing to do with the shutters unless you damaged something taking them out. I used a survival rope saw. Cut mine out with grill in place. Left the top center and bottom. Still no codes or issues to this day.
Umm wax melting. Perhaps on a dial safe thermostat. The spring in the thermostat expands and contracts regulating the amount of coolant flow through the radiator
Got my shuuter damaged and then replaced by a new one. The new one was faulty or installed improperly. As a result i have a shutter always closed and a check engine light always on. Because of the check light the remote engine start is not working
@@yangtroy1having the same problem with my 2019 Jetta. Mechanic wanted $600 for the part and $150 for labor. I ordered it online for $250 and he will install it when it gets here in the next few days. Are you saying you had yours fixed and the check engine light came back on? Worried about potentially having that same issue… these freaking things.
This is a solution looking for a problem. Putting more crappy plastic parts on a car does not make it more efficient. It just costs more to repair. The few drops of fuel saved are wasted shipping this crap over from china.

Called BS once I heard reduce emissions and $$$$ by 2023. Lol
it saved the first owner
2 fuckin grand for some plastic and an actuator?!?
I know,,, On the freeway let's block half of the radiator from cooling. BRILLIANT IDEA💡

Wait, wouldn't them be closed increase drag since it is essentially a wall now? I'm confused

@@jakejones5736 exactly.
People worrying about overheating should not.
Bmw G30 achieved a CD of 0.24 thanks to that active air flap.

This was super informative, thank you very much.
Thanks for this video. Couldn’t figure out what these were for.
Excelente explanation, thanks
But will it throw a code if removing the shutters
Yes
@duncank6915 I have removed mine, and no codes yet

Is it safe to drive the car with the code popping up
My gauge is right below the H is that normal but then the shutters open and comes down
I’ve never had it overheat , or the warning come up or the check engine
So is that normal?
Below H is overheating and severely abnormal, your shutters are not opening
@@seatime674 I took a piece of pvc and cut it to size and slide it in the vents on both sides
Hasn’t gone over normal temps at all ever since 😃
@@Erweenie I can't picture that, you mean wedging pvc in there to force the slats open.?
@@seatime674 yeah it’s about 1 3/4”
@@Erweenie you didn't get a check engine light? Typically that happens
How can I cancel them without a check engine light on??
I cut cut all the shutters off my except for the one that is attached to the motor. No engine codes as the truck still thinks their in there.

They make no sense. It’s just an extra thing they on vehicles so that they sell their parts.
They are apart of a category called fuck me.

Can’t I just disconnect them so they stay open cuz obviously it doesn’t do shit
Another shitty design to rip off consumers.
Why would anyone make this nonsense into cars
Federal MPG requirements. Elections matter.
Of course ford would use this bull crap system
Chevy is using the same crap system as well.
@@nickyvanderhoof2281so is Subaru. Looks like most companies will be using these
Chrysler is too😢
