My dodge doesnt smoke in the am. I thought it did but then I realized it was just steaming the frozen bushes. I dont plug it in(apartment) but it runs 10 or so before i take off. And I use redline winter fuel additive(I get it for like $3 a bottle from work)
 
I warm my Yota up just for me, if not I'll freeze on the way to school. My old Ford I don't, doesn't have heat. But it mainly depends on how cold it is and how much of a hurry I am in.
 
I've found out quickly that my new to me ZJ does not like to roll cold. Never really done this until I bought my bike and was riding it every day from May till just two weeks ago. That ZJ tranny just doesn't like to shift in the cold and the tq converter I guess just holds the RPMs high and won't shift into 4th till its nice and warm.
 
I let it run for about 30 sec before I roll out of the drive. I then "ease" up to speed.
 
I always crank it up for at least 10-15 min before I leave. Truck has zero power until it warms up, plus I hate sitting in a cold ass truck.

I typically expect it to be running abotu 10-15 min but its more like 20-25 as I'm slow getting out the door in the morning at 5am...
 
I prefer to let it warm a bit, esp the Olds, the 3100 V-6 clacks when cold, even in the warmer times, just not as bad. When I take off and it's cold, I ease into it. Takes about 2 miles before the temp starts rising.
At work, I have a friend who can get away from his job a lot faster than I can, he starts about 10 cars in the morning.That works out great esp when it's frosted over.
My Hauler(with carb) needs some time to warm up, for both the engine and gear box

chrysler trannies have drainback issues and need time to build up pump pressure. it won't shift into od because it's temperature controlled.
when it's this cold all automatics should be given a minute or two of idle to get the fluid moving and thin enough to be pulled through the filter.

Yeah, the auto on my 4runner won't shift into OD until it's been running awhile, A340h. IIRC the AW4 in my old XJ did that too.

Yes. My company van (6.5 chevy diesel) does not like cold weather at all. I think the fuel module is crapping out on it so it runs REALLY rough for the first 30 seconds or so, lots of white smoke and it sounds like a rod is going to come through the side of the block.

Sounds more like you've got a couple of bad glow plugs.
 
I've been letting mine warm up about 10 minutes this week. I have an aeroforce digital gauge that plugs into the OBDII port and reads the trans and coolant temps. They were both 17 degrees when I started the jeep this morning. When I got back in the jeep 10 minutes later coolant was 153, trans was 41.

I voted NO, but its not like I turn the key and drop the hammer. Unless I have to scrape the windows (like this morning), I am def. rolling way before 5 minutes, 2 minutes max. When its idling, I'll go thru the gears, try and warm up the tranny. Even on the automatic, I'll hold the brake and let it idle 5 seconds or so in each selction R-N-D-O-32-1

I've always heard that putting the trans in gear will help heat it up faster, but on these mornings it has only made about 3-5 degree difference after one to two minutes.

My jk hasnt gotten past 140 degrees in these temps and actually in the morning on way to work(11 miles) doesn't get past 110. I have an after market cooler added on. Is it bad to run the trans with fluid at those temps? I know the converter locks up at 88.
 
cooler is always better when it comes to trans temps. there is a fine line between cool and too cool.
in transmissions that are computer controlled most have a temp sensor of sorts and it must reach certain temps to allow lock up. atf doesn't change viscosity much, but the slight change makes it a little harder for valves to function because they are designed to operate at normal temps.

Mine is an 08 JK with 42RLE. Do you think the 110-140ish is to cold with the torque conv. locking up at 88?
 
in the 6.0 hell no, colder feels like another 50hp.
 
I crank the Ac up 10 to 15 minutes before I head out. This is mainly so I can be warm as it takes 10 miles to get warm if I dont.
 
The diesel I plug up. It starts easier, the fluids are warmer and the fuel milage is a little better.

The jeep I let warm up for 5 minutes or so.

As it got colder this year I realized that a 22RE with a 160 degree thermostat doesn't produce heat. It would have to idle for 30 minutes just to get mildly warm for the 8 minute ride to work. The 78 gets a warm up period because its a carbed 460, but has no blower resistor so it doesn't get driven much in the cold.
 
I let mine warm up for at least 10-15 in the cold mornings. Cool thing with my heep is that you can pull the key out of the ignition while its still running. Makes it really convenient to let it warm up without worrying. Ummmm i just remembered that its been warming up here at work for the past 30 mins or so. Time to go home!
 
Sooo.... I was reminded this morning, quite directly... that if you're going to crank a 5spd p/u to let it warm up, and your driveway has a slope to it... be sure the parking break is on before you leave it out of gear and get out... otherwise it just might roll backwards into your Mazda...

hA..Back in the day, I had a chevy berreta with a bad e-brake.
I let it warm up one morning, and when I came back outside, it had rolled about 50 yards down into the yard. The back end had rolled up onto a small apple tree. The tree had bent way over and was now holding my rear tires at least 4 ft off the ground. The front spoiler was dug in from the angle.

Luckily it was front wheel drive and I was able to drive it down.:driver:
