Hey guys, so as my truck came from California, and here in Saskatoon its gets to -50 celsius, I figured I'd put a block heater in. I didn't see a DIY anywhere so I decided to make one.

First things first, remove the air box assembly.



Then, remove the inner fender. Honestly, this was the hardest part of the job, haha.



Here you can see the freeze plug you have to remove.



Now, before you remove it, open your rad cap (make sure the engine isnt boiling hot) and then drain the coolant via the lower rad hose...this makes a big mess.



Then, take a punch or screw driver, and beat in the edge of the freeze plug. Afterwards, just haul it out with a set of pliers.




After the last of the coolant has spewed out, give it a wipe clean, and grab your block heater. Here is the motorcraft one I bought from ford for 35$



Now, take a little bit of NON-petroleum based grease and lube up the o-ring.



Take it, press it into the hole, make sure its seated in the whole way around. Tighten the screw...this opens up the wing nut and makes sure the plug stays in place.



Then plug the end of the cord in and run it through the grille or where ever you like. Put the inner fender back, and then the air box.



Make sure to refill the rad until full, turn on the engine, and let it run WITHOUT the cap on in order to get some of the air out. Top up and then youre ready to go :)

only thing I can say is instead of making a huge mess with the coolant you can get a piece of 3/8" hose of some sort (clear nylon works great) and put it on the drain petcock of the radiator that's on the lower passenger side and put the hose in a bucket and let it drain out, it takes longer this way but you can put the coolant back in if it's usable...

Look between your grille and radiator. It's not standard equipment, never has been. Always been an option. Unless it's a canada truck(I'm told).

My credo
The fun begins where the pavement ends
Canadian vehicles require block heaters. Check the lower "smile" opening in the grill or between the grill and bumper.

Be careful which freeze plug you knock out. The heater won't fit in all those holes. There is some webbing in the way on some of them. Can't remember which ones. Ask me how I found out... Fortunately, mine was on an engine stand when I made the discovery!

I really wish this thread was up about two months ago! I could've done it with the engine hanging on the picker!!
