Alright, so I got my new block heater in the mail yesterday. I got around to installing it today.

First thing I did was to jack up the front of my truck. Then pop open your hood and take a look. You'll probably want some sort of light.
Image

Yeah, yeah. I know I need to clean. :ugh3:
The area we are looking for is to the left of your brake booster. (the big round thing with the fluid reservoir).

If you look down, you can see your exhaust manifold. The hole for the block heater is right near this.

You can see an exhaust sensor in the middle of the picture, the hole for the heater is right to the left of it.

Image

This is a picture from underneath. If you look behind those two bolts you can see the hole it slides into.
It helps to have someone guiding the light.
Image

Goofy cat. :D
Take the supplied grease and smear it all over the heater unit.
Also put a liberal amount into the hole on the block. Don't put grease on the terminals though!
Image

You can see the heater installed in there. The clip should snap into place on the side of the block.

From underneath.

I gave the heater a good spray with some electrical cleaner spray, just for kicks.
You then will want to hook up the cord.
Image

I tried to keep it off the pipe, I think it will be fine? I couldn't seem to find a better way to route the cord. (suggestions?)

Heres a closer view.
Image

From there I took the cord along the side of the fuse box and battery and brought it out front.
Image

From there I ziptied it slightly behind my license plate to the lower grill there.
Image


When you've finished just plug it in for the night.

Suggestions welcome.

Looks good I just have a few things to add and I'll post a few wiring pics.

First when you install the heating element you have to make sure the clip is rotated to the left side (with the plug triangle pointed up) if you dont do that it wont clip in, or your plug will point down. It will only fit in 2 ways since the element is "keyed" at the end.

Also unless you have some really rediculously tiny hands you wont be able to just reach up and put it in. A little trick is to put your thumb over the plug and then put your index finger on the other end of the clip, i tried a few different ways to plug it in and that was the easiest.

Here are my pictures

I went a little further up and to the right. Away from all that heat of the headers.

I also zip tied the little cap on, when I was running the cord around it fell off a few times, and it didnt stay on the end that well. but with the added zip tie its perfect.

There they are. Take from them what you will :)

Couple more little notes.

The clip will rotate on the body of the heater. So once you get the heater in the hole, you can back it out a little then rotate just the clip so that it aligns with the catch.

I routed the cord around the outside of the battery (torwards the tire side) then came through the hole for the headlight wiring. The rest is the way Tacomer did it. Going on the outside of the battery gets you to the end so that it leaves just about 4" to pull through the grill.

I'll try to get a couple pics of the wiring to add here tomorrow.

I know this is an old thread, but for anyone wanting to do this and take it one step farther, I'll tell you what I did on my F250 diesel. Now the only reason I use the block heater on my F250 is because all '03-'04 model 6.0L diesel Fords came with them from the factory. I usually start plugging it in when our nights start getting down in the 40s, not because it needs it, but it cuts back on the strain on my batteries, the coolant is already hot enough for the thermostat to open up so that the heat gets hot almost immediately, and the truck isn't so sluggish. If only they had a transmission heater so that it wouldn't shift so rough for the first few miles in the winter time...

Anywho, what I did is I cut off the factory male plug end, and went to the local electrical supply store and bought a recessed male receptacle. Now on Fords, the receptacle assembly was small enough to fit behind the Ford emblem, and then I did a little modifications to my grille emblem. Went to Lowes and bought a spring-loaded cabinet hinge, mounted it to the emblem/grille, and now when the emblem is closed it looks just like any other Ford grille, but then you can magically open up the emblem and there is my plug.

My initial reason for doing this was because when I get home I usually have at least one hand full of crap when I'm going into the house, and it's hard to hold both ends of the cord to plug it in with my hands full. So I wanted to make it to where it was just like plugging something into a sturdy wall socket where you only need one hand, and this was the idea I came up with. Now I'm trying to get rid of my F250 so that I can get me another Tacoma, but when I do get one I doubt I'll put a plug on it because the coldest we ever get is like 20 degrees. But you could probably think of something similar.

Would you kindly provide pics or link to the work you did to your ford?
