If you had one I'm pretty sure you would have found the plug by now. No plug = no heater. Simple.

 

Look at your window sticker. It should tell you ALL the options that came on the car,
including the engine block/oil warmer.

 

Here are some pictures on finding it:

You'll need to remove the radiator cover. There are 4 bolts

and 5 plastic pins

slide the cover back or take it off so you can look down in between the radiator and the bumper

This is the plug you'll see.

The part of the connector that I'm holding did not come with the car. The cable that came with the car
ended here.

I had to purchase the converter cable that plugs into an extension cord and the plug I was holding in the previous pic.

It wasn't obvious that I had a block heater until I removed the radiator cover and found the end of the cable. It's a flat connector with a rubber cover.
I bought the adaptor cable from the Ford dealer, cost $40.00 and they had to order it.

Btw, PonyExpress is correct, I just checked the window sticker and it was listed.

 

Probably not worth the hassle since we usually only get a few sub 0 days a year. I just found my window sticker and don't see it listed so I guess I don't have one anyway. After doing some searching I thought of a couple other ideas. Use my jump starter when its really cold for less battery wear (I know a trickle charger would be better, but I didn't buy that kind) or how about just using a heating pad under a blanket over the battery? I know that may be a little ghetto, but I can't see how a car batter heating pad would be much different.

 

I like the heating pad idea. I had one of my techs set a incandescent work lamp on a car seat during his break, and it melted a hole in the seat...all the way though. Just happened to be a new police car that we were installing the radio and lightbar.

 

Funny, I have an engine heater (120 Volt) in my Mustang which I do not drive in the winter.

 

Keep it tune right and good battery it should be good to start

 

yeah, I know it will start. I just want it to start easier with less wear and tear on the battery and motor. I think I'll just ride it out this winter and get a carport with the sides in the spring and maybe put some kind of light in it.

 

y'all do know that the engine heater isnt for the starter or battery. Its to keep the oil thin enough to be pumped thru the engine. The colder it is the thicker and more like molasses your oil becomes and the oil pump cant pump it to lubricate the engine.

 

dont warm the oil, neither do http://en.wikipedia.org/wiki/Block_heater that replace a freeze plug.

A warmer that goes on the pan, however....will warm the oil.
