Plug in or not?

This is my first winter with this truck- 05 f350 with the 6.0 turbodiesel. At what temperature should I start plugging in the truck, and how can I tell if the block heater is working?

Everyone's plug-in temp is different. I live in N. Ga and my magic number is 15*. Only had to plug it in a couple of times this year. You can tell because the motor gets up to temp much faster and the cab heat comes on quicker. It all depends on if your truck does good or bad on below freezing starts. Mine does fine so i let it get to 15*. Just my preference

I usually use mine below 20 degrees F. When I plug it in, I can hear a real light buzzing noise under the truck. Makes a world of difference IMO. Heater warms up a lot quicker and engine starts easier.

Right around 20* for me. My truck is lucky usually its kept in a heated garage. But for the times its not I do keep it plugged in. Some people put there truck on a timer I dont. I just plug it in before I go to bed and unplug it when I get up and go to work. I do that cause I may get a fire call in the middle of the night and the truck is warm and ready to go...plus the heat comes up quick and with a crew cab there is a lot to heat up so every little bit helps. As you drive and get used to your truck you will know at what temp you should plug it in at.

How cold does it get where you live? You'll have to come up with a temp yourself, as this engine should start in pretty cold temps by itself.

You'll be able to tell if the block heater is working by how it sounds when you start it. If it's below freezing for a couple of days, let it sit out side w/o being plugged in. It will sound aweful when you start it. Then plug it in overnight and start it. It will sound much better if the heater is on.

Thanks- I've been plugging it in since it dropped below 25 here in North Central PA, and last night, tonight, and tomorrow night it has been and will be below 0. I noticed that with the recent snow, there was no snow on the hood, but the grill and headlights are covered in ice. I figured the block was heating and then the runoff was refreezing on the front of the truck.

Start up is pretty much the same as warm weather, so I guess everything is working well.

Brrrr

Up here it has been about -8 lately. We plug in normally and run a light weight oil 10W30. I use a timer which turns on about 3 hrs before needing to start the trucks. For every 24 hr period (I just figured it out on another forum) it will cost around $3.60 in electric bill. (.15 per hr)

What kind of oil are you using that you can get in 10w30?

I only plug my truck in when it drops below -15 deg. It starts fine in cold temps but when it gets real cold the exta heat in the engine really helps. Also helps heat the cab a little quicker.

When your electric bill comes in, see what they charge you per KW and and multiply that by the number of hours you are plugged in. The heater is 1 KW
my rate is 13.6 cents per KW.
