Yep, the MPC says that's a 600W heater kit for the 300 six, all years.

You have no idea how nice it is to have a block heater in a cold winter;).

You hop in your car when the temps are sub-zero, and it fires up like a warm summer day and blows heat right away! It's a beautiful thing.

I drove VW diesels for years, and if you don't have them plugged in, you'd freeze to death for the first 10-15 miles while the thing actually developed some heat in the cabin lol.

Never been around a vehicle with a block heater, even though I lived in the Chicago area for a while.  But I usually had my vehicles housed in a garage most of the time.

Now, however, with a massive lump of cast iron under the hood it takes a loooong time to warm Big Blue up.  I remember the trip Janey and I took into Arkansas last winter when the temp got down to 12F at night.  It took FOREVER for the heat to come on.

So I can see the benefit of a block heater.  

When we were stationed in Fairbanks AK, our 76 F250, 6cyd, had two block heaters, a heating pad the battery sat on, and a heat pad glued to the bottom of the transmission. There was also electrical heater in the cab, and frost shields on the doors and rear windows.

With all that, there were still mornings when we had to use a kerosene heater blowing hot air under the truck to warm things up so I could turn the steering wheel.

For the 6 years we lived there, I don’t recall any time that 6 cylinder did not start. Even at -50 to -60 degrees

We had tires frozen to the ground, hubs that could not be locked or unlocked, windshield wipers frozen to the glass. And doors frozen shut, etc but it always got me to work.

Stupid truck! Sounds like a good day to stay home!

I had an 88 with the 7.3. Had an appliance timer that came on 1-3 hours before I went to work, depending on the temperature, sure was nice to start that thing and defrost the windshield.

Lol!  I could say exactly the reverse, «never been around a vehicle without a block heater».

It's worst for Diesel engine, if compression is just getting a bit low after couple of years, living without a bh is just a no go.  The cold fuel can't reach the explosion point, even with couple of glow plugs shots.  I had some VW cars in my younger years, had to not forget to plug the car before going to bed, in order to go to job in the morning.


In these past times, a bh was an optional add-on when buying a new car.  These days, it's usually included in the base package.

 If the stupid weather keeps up I may need this... knock on wood but I've not had issues starting my 300 (as long as I give it a kick or two of gas to prime the choke).
