6.7 engine block heater
I can't remember who posted it, but I took the advice to string the extension cord over my driver's side mirror so that I don't forget it's plugged in....
For many of you the south isn't cold but it's cold enough to make the turbo fuss a little.
But I'm easily annoyed by pointless noises so that's my problem...haha.
Now if it gets as loud as Crazy001's original turbo, then I'll be concerned.
The cord over left mirror was mentioned somewhere around here and was/is good advice.
Just don't forget the cord is on the mirror or it'll be an expensive mistake!
No issues but will burn through some diesel.
element $21.91, and cord $97.75, I know I coulda got the cord cheaper as aftermarket, but I mean it's a $50,000 plus truck, I never understand the quibbling over small money parts on a very expensive truck; and I want the FoMoCo wire with all the heat protection wrap, and the little push in anchors so when I install it tomorrow it'll be exact as oem.*
I also remember reading somewhere(dieselstop maybe) that the reason for the big $$$ for the dealer install is because they drain the coolant for the install, and won't reuse it, and it's pricey. I'm going to just back out that freezplug and stick my finger over the hole as I thread in the heat element, I might lose a little coolant, but I am not draining the whole thing over it.*

Well I installed my block heater yesterday. My intent was to video it and post it like epic cowlick does, but the video came out like crap- you can barely hear the audio at all- long story but the camera I was using is a helmet cam that I wear when I'm on my motorcycle, and I modded the mic a bit so that the engine noise wasn't so overwhelming in the movies, unfortunately it seems the camera will be no good for much besides riding videos.*
Anyways- back to the block heater install.
I think we all know where the freeze plug that must come out is located, right side of motor above starter. The freeze plug has a recessed hex head. It is a 9/16. I happened to have a set of Alan driver sockets like these that I use on the axles on my motorcycle.*
If you don't know where the freeze plug is located refer to This picture:
Or page 11 in the 6.7 coffee table book here

Admittedly I wasn't sure how tight that freeze plug was going to be in there. I started out with my hex socket on a regular size 1/2" drive ratchet. No dice- couldn't budge it. I figured I better get the best angle I could get, so I went ahead and removed to inner wheel well shield. It comes off pretty easy. It's pretty self explanatory to remove so I'm not going to get into it, other than to mention the plastic push through anchor that is from a wire bundle located under the passenger side battery can be pushed out of the wheel well cover after you remove all the bolts and drop it down a bit. You will also want to make that the first item that you reinstall before putting the wheel well cover back in place, because you can't access it from the top without removing the battery, and battery holder. Not worth the effort since you can just stick it back in place before you put the cover back up.
So back to the freeze plug- even after removing the inner wheel well cover I couldn't break the torque on it and break it loose. I switched to a larger 12" long 1/2" drive ratchet and was able to get it free. I just loosened it up enough that I could turn it by hand and then got ready with the new heat element to make the switch. My intent was to make a quick change and not lose very much coolant in the process. This is also another good reason to remove the wheel well cover. Otherwise there'd be no room for both hands up there to make the switch. I have to admit I was a little unsure what to expect when I pulled the plug out- I had visions of the coolant spraying out all over the place when I pulled it, but it wasn't really that bad, I made a quick switch (not as quick as Indiana Jones with the golden monkey head, and bag of sand) but it was quick enough that I didn't lose very much. I'd say at most a half pint to a pint judging by the size of the puddle on the driveway under the truck.
Once I had the heater in just a couple quick turns the coolant all but stopped dripping out. You'll need a fairly large socket to fit over the heat element and tighten it down, I didn't have an SAE size socket large enough to fit it, but I had a large 1/2" drive metric socket that fit it well, (again motorcycle related) it was a 32mm size which is about * * * *1-1/4". I tightened it pretty tight and decided I'd throw a torque wrench on it so I'd have a reference number to use. Seat of the pants gauge compared to how hard it was to loosen I'd say it was approx 80 ft/lbs.*
Once the heat element was tightened, all that remained was connecting and routing the cord. The connection is very straight forward. It just pushes in and the metal clip at the end of the cord pushes over the outer threaded part of the heater, you'll know what I mean when you get there.*
Routing the cord was a bit of a challenge for me simply because I wanted to try to figure out exactly how it would be run if ordered oem, I was using the plastic push through anchors as a reference looking for a hole that they should fit into. The cord came with about 5 pr 6 of them already attached to the cord, you can see them in the picture in my post earlier in this thread. I tried routing the cord about 8 different ways/paths before I got frustrated with it and just decided to get it done and not be so totally **** with the cord routing, just making sure that the cord was well routed, anchored in a few spots and not going to be damaged or chaffed by anything.
If anyone wants to post a picture or two of the way their cord is routed if they had one installed from the factory I'd appreciate it, I may just go to the dealer and ask the sales guy if he'd mind showing me a truck that has one so I can take a peak at the routing and see how close I got it- maybe re-route my cord if I'm way way off.*
All in all it took me about 2 1/2 hours start to finish- but it can be done in an hour or less if you don't spend all kinds of time routing the cord like I did.
I wish the video had been usable so I could show you a few of the steps, particularly the swap between the freeze plug and the heater element, so you'd know what to expect if you decide to do this yourself. Just know that even with basic abilities, this can be done in the driveway with little difficulty. Worst case scenario if the swap between the freeze plug and heater element goes bad for you, you might need to buy a gallon of Ford coolant to top it off again.
One thing I guess to mention, it was on my mind starting the job whether or not I should put anything on the threads of the heater element before I installed it. Like locktite, Teflon tape, or anything like that. When I removed the freeze plug it was evident that there was nothing at all (beside the black O-ring) on the threads, so I didn't put anything on the threads of the heat element either. Better judgement tells me I should have at least put some Teflon on it, not so much to prevent it from leaking (the o-ring will do that), but for the future if I ever need to remove and replace it, I think I'd be able to get it out easier if there were some compound on the threads- however since I'll be able to put a big beefy six point socket on it, I'm not overly concerned about it being impossible to remove either.
Hope this helps someone else, happy to answer any questions if anyone has any. Happy I got it done before the real cold temps hit New England. I hate the way it takes so damn long to warm up when it's cold in the morning, I'd have to drive for 15 miles before the gauge would even start to move, when it was only as cold as low thirties- which we've had a few mornings of already.

For future reference of others who may attempt...
DO NOT use any Teflon tape, pipe dope, Loctite, etc. Just lubricate a new O-ring with clean coolant and install.
Tighten to 30 lb-ft (41 Nm) or basically seat it and snug it. DO NOT over do it or you could damage the O-ring.

I know lots of people like to use timers for their block heater, but the issue is; there really aren't any (that I have found) that will fit into a box like that.
There is a type of duplex outlet that actually has remote control capabilities, I know it sounds high tech (and it is sorta) but very affordable, and easy to install. They are part of a line called x10pro, and they are a home automation type of product. I've included some links to the best prices I have found for a simple set-up that you could run your outlet with. Seems like about a $50-$60 dollar project if you're a do-it-yourselfer. Seems like a decent solution, to keeping your plug weather tight. I'll add it to the list of things I may never get around to, but someone more ambitious than me might find it intersting.
