Block Heater ?
Hey guys, I am getting ready for winter and I have a ?. Does the Block Heater in 6.0 have Thermostat type setup or is it always on when plugged in? I always assumed it would be on when plugged in but now i'm not sure. 
Thanks in advance.

set up a thermostat and a little ice cube relay
to keep the engine about 40 degrees....
i plugged mine in one cold night (for california)
and the next morning, the engine was hot....
now i know why... i figured it would have a T stat
built into it... 1 KW is 1 1/3 horsepower.

This morning I plugged the block heater in. My Scangauge read 39 degrees.
1 hour later it was 80 degrees.
2 hours later was 94 degrees.
3 hours later it was 103 degrees.
4 hours later it was 110 degrees.
5 hours later it was 116 degrees.
Yes, 39 isn't that cold to start, but was interesting to see that it went from 39 to 80 in an hour.
Currently my oil temp in hour 3 is 77 degrees. It was 40 at starting point.
Oil temp after 4 hours was 91 degrees.
Thus the suggestion of a timer!

Your truck should have one. 05-07 were hit and miss, but 03-04 were stock installed.
First, you can feel just above the starter (passenger side) for the cord where it plugs into the block heater. It should be there, unless someone removed it before you bought it, assuming you haven't owned it since new.
They zip tied the plug end up real tight behind the bumper. If you stand looking at your truck, just to the right of fog light, or where a fog light should be.
It's hard to see. I looked 3 times before finding mine. I needed a flash light in the middle of the day!!
Block heater manufacturers do not recommend starting the motor when it is plugged in. Just saying.

I almost never plug my Truck in. I do have a remote start that I use everyday and let her run for 10min or so. However, in the winter, when we go up north(usually a week) I leave the truck plugged in 24/7 and unplug it to start it every day. It has gotten very cold there at times(-30F).
