I started mine with 4K miles with only a couple of degrees out. The clutch was very soft and felt very dampened when I released it a couple times in neutral. In normal driving I tend to shift below 2K RPMs but when it is this cold the engine needs to be reved to 2500-3000 RPMs in order to make the shift. The brakes were fine but I did notice after pulling out of the car wash the effects of wet brakes.... :)

Everything works pretty good until you get down to about -30F. The brakes get a little sluggish on releasing. Much colder and the ABS goes stupid. The engine doesn't require an idling period but it does help the clutch and power steering if you give your care a few minutes to wakeup before driving off.

How's the steering? My steering is very sluggish when the temperature goes below 32F, about a 62F difference. :D

The steering takes a little more effort until it warms up. Even at -40F it only takes a few miles before I can't tell the difference.

That’s why I live in Florida: everything works well at 72°.

Even at -40F...

-- Off topic

Do you need special tires for those temps? I've heard that rubber boots will crack under temperatures like that...

Anyone get like a wuuuur noise upon first start. It occurs immediately following the first time it kicks over.

Yes, I have heard the whirl. Not sure what it is though.

The only problem with the tires at -40F is that they have a flat side where you have been sitting until you drive about 3/4 of a mile. It is like driving over the cobblestones.

Yes. One time it lasted for about 5 seconds (sounds real nasty). So far it's the only "potential" problem with my V.

Does the whurr noise to which you are referrring sound like an electric motor under the car? It might be the electric fuel pump pressurizing the system and is normal. (it is located inside of the fuel tank on most cars these days, if I am not mistaken). You should be able to hear it as soon as you turn the key to "on", before you click it in to engage the starter. Should usually last a second or two. It also runs when the engine runs, but is usually masked by other noises.

if it is coming from the dash, it might be your DVD or CD player booting up......

Were talking about startup when the tempatures are around 10-15F or lower.

Your right about the fuel pump, CD/DVD player, leveling shocks...

It happens after I start the car. Immediately. The noise comes from the engine compartment. I've only herd it like twice, and it only happens when I;m starting it when it has been sitting for w few hours (8 or more).One Jetta I had used to make the same noise, but louder and longer. I beat that car so I would understand why it might do that. This is my baby, everyone that I know understands that car is the reason for my existance. I treat her like gold.

That's exactly what I have.

It doesn't have the screeching sound of a slipping belt. It might be a pulley problem, some Corvette owners have had crank pulley issues. Even my C5 (LS1 not LS6) had an internal bearing problem with one of the pulleys.

It's the Nav dvd spooling up. Remove the dvd and see if you still have the noise.

:histeric: You're kidding right? If it's the DVD player, you can hear it from 50ft away with the doors closed (it got my neighbors attention).

I'll still give it a try.

I have the sound too. goes away immediately. Sounds like a supercharger whine. For some reason I assumed it was the speedo cable. Don't ask me why.

No Whurring noise for me... But I do have other cold weather issues....

Do you notice the gear shifter vibrating harshly between 25-35 mph when the transmission temp is aboutr 50-70 degrees....

Do the tires have almost no traction for at least 5 miles... Cause a lot of spinning and hop if you attempt to pull out hard when it is cold???

Have noticed the lagging clutch, but all hydralic clutches experience the same thing... My Honda, My First CTS with the Getrag, The V with the Tremac.... The clutch in my Jeep doesn't have this issue!

It's funny how this thread came back today, because my whirring / screeching noise has gone away. :confused:

My steering when cold? Like on ice. Takes almost zero effort and has little effect. Turn the wheel when 30 degrees out or less and first driving and it feel like I'm driving on ice.

The screeching from the DVD/CD player? That's a bit of VR (not virtual reality, Velvet Revolver to you) spooling up :sneaky:
