Traded in my 2001 V10 for a 2010 6.4 Diesel a few months ago. The new truck has the plug in the grill for the block heater. It was plugged in this morning for about 1.75 hours but did not seem to do anything. Cord has power, but did not seem to do anything. Am I missing something? I have a short ride to work (<10 miles) and tried this so I could have cab heat before I actually pulled into the parking lot at work.
Thanks for the reply. I also just got off the phone with my local dealer. He indicated that block heater was just for the oil (which I understand). I guess I misunderstood the owner’s manual; it led me to believe that the plug in that location was for the quick heat option. Some trucks apparently have a rapid heat option for the coolant fluid that will get cab heat quicker, its now obvious I dont. I guess I will have to wear my gloves to work.

There are some very efficient coolant heaters that can be added to your truck without very much work. They can be spliced into the heater lines and give you the best of both worlds. However if you warm up the block by warming the coolant you shouldn't need the oil heater. Your truck will love you and you will have WARM HANDS quicker.
All 6.4 engines have a block heater and the element heats the coolant, not the oil.
ENGINE BLOCK HEATER
An engine block heater warms the engine coolant which aids in starting
and allows the heater/defroster system to respond quickly. If your vehicle
is equipped with this system, your equipment includes a heater element
which is installed in your engine block and a wire harness which allows
the user to connect the system to a grounded 120 volt a/c electrical
source. The block heater system is most effective when outdoor
temperatures reach below 0°F (-18°C).
If it seems the heater isn't working you need to OHM out the cord to check for a compromised cord or the element itself.
Should be around 10 ohms give or take a few. Also, keep in mind the cord itself is a 2 piece design with the flat plug located forward near the front frame rail and bumper bracket.

Thanks for clearing up which fluid we were heating. Since I don't own a 6.4 and probably never will all I could do was respond to the information given. Block heaters can work in either fluid it just depends on where the heating element is placed.
