Ford: I propose a new cold-weather setting!

[tr7driver]

I think the grill shutters on my C-max appear to be designed to let less air circulate around them than the shutters on my Fusion. Just saying it looks that way to me, though the upper grill on the C-max directs a lot of air at the engine behind the radiator. I'm looking for an attractive way to block that top grill, maybe remove it and stuff it full of foam. The c-max energi ICE seems to warm up quicker than the Fusion.

Maybe you can't, but 60mph air is much stronger than you.

Funny, Hitting a Deer at 50mph couldn't move them either. :lol:

Waldo "And yes, I have seen wind tunnel data showing grill shutter data. They typical reduce the Cd by about 0.01 to 0.015." It is interesting that most members didn't see a difference in HWY MPG's with the update with shutters closed. ;) :shift:

Cause they've always been closed. And even if there were a difference, the difference in fuel economy created by a difference of 0.01 in drag wouldn't be able to be measured repeatably. But that doesn't mean over the long term, or in a lab test, it doesn't make a difference.

Can you personal verify this? I actually tested this with the results in Post #40, they have been open at HWY speeds. At HWY speeds you will get at least 190*F.

The update changes the opening temp from 190*F and fully open at 213*F to Opening and fully open at 210*F to 215*F. Have fun testing. :)

All that really matters is that they are closed during the EPA coastdown test.

Interesting reading on the grille shutters.

 

I borrowed my friends scanner and did some reading and unscientific testing on the shutters.

 

When the engine is started, the shutters are cycled open and closed so the PCM can determine the travel range. If the range is not within a predetermined value, a trouble code is set.

 

The shutters have a range of 16 steps.

 

Today, the ambient temperature is 45F and raining. I was monitoring the shutter commands, shutter position, speed and engine temperature.

 

First, this engine seems to have a difficult time warming up. With the heater on, flat road driving at about 40 mph, it took about 40 minutes for the engine to reach 185F. On a faster highway drive, it stabilized between 190 and 205F.

 

Below 190F, the shutters stayed fully closed regardless of vehicle speed. Hotter than 190F, they partly opened, to about 50%. They were never commanded to open greater than 50%

 

When the a/c is on, they opened to 40%

 

The electric water pump was only on when the heater is on or when the engine is running, otherwise it was turned off.

I don't have a scan guage to tell me what the exact temperature is but I do monitor the temperature guage that I have configured in my "My View". On very cold Minnesota days mine seems to reach the normal operating temperature (middle of the guage graphic) in 5 minutes or less.

HB covered a lot of this back is August, 2013. It's an interesting read and might answer some questions that pop up from time to time.

Five minutes or less is a quick warm up compared to mine. You must get hot air from your heater within a few minutes.

 

Is your car parked in a garage overnight?

Just checked again with ScanGaugeII and at 175*F WT line is in the center till about 225*F at which point it starts to move up to top WT line at 247*F. At which point you will get the warning that car is stating to over heat. BTW 175*F is still a ways from 202*F, the start of ICE operating temp.

Is that FWY driving and do you have grill blocker of some type? At 180*F thermostat starts to open and is fully open at 202*F slowing down any temp increase for awhile. Even with Grill Covers on it takes 15miles to get up to 207*F when it is cold. I would be interesting to see what a ScanGauge would read on your car. :)

My approach, stuff the grill, use seat heaters, and turn Auto on once I get moving. Im warm, car is happy, and I get 38-40 MPG. Good enough for me.
