2016 f150, 5.0 Engine block heater plug

[Jay3702]

So I pulled the extension cord off my block heater and the one prong broke off ugh it’s cold out! Ha
I thought there would be a quick disconnect harness so I can replace the plug but I can’t get it to disconnect. Now what? Just replace the plug itself? I don’t want to use a hardware plug with no protective cap

Doesn't the cord have a plug into the heater so you can't replace just the cord?

 

[Jay3702]

I can’t even see where it plugs in at the bottom of the engine **** in the way

If you don't want to unplug it from the engine, the only alternative is cut off the broken end and find something at Home Depot to replace it with.

Just put a new plug end on it for now and change the whole cord in spring if you want.

Yup, the factory ones last a few years, and after that I seem to have to replace the aftermarket ends every two or three years. Part of life here ...

What does a block heater warm up, the oil in the pan, antifreeze....????????
Down here in Louisiana we don't have such an animal on our engines (well, I don't anyway).
I had to go to Walmart about 1 PM yesterday and had to turn on the a/c.

What does a block heater warm up

It's a heating element that is installed in a frost plug or screw in fitting of the engine block and heats the antifreeze. I have both a Block heater and a oil pan heater on my F150.

I plug the block heater in for 8 to 2 hours before a engine start at or below 0f, and the oil pan heater as well 1 to 2 hours before at below -15f. That's the plan sometimes it doesn't work out that way.

Block heater is 500-700 watts, oil pan heater 150 watts.

Is it possible that the starter wouldn't be able to turn the engine over if you didn't have an oil pan heater? I have seen those oil tests where the oil was frozen in temperatures well below 0 degrees and it looked like honey when it flowed. I bet there is some serious knocking from the engine if that thick oil were to try and flow at startup.

Any engine in good condition with a good battery should start unaided down to -20. The heaters do help some above that making it EASIER to start and allowing a faster warm-up.

When I was running my Canadian Ford diesel fleet, I ran a factory block heater, 150W oil pan heater and a battery trickle charger all wired through a shore plug on the truck. Diesel fuel additive every second fill up as well.
If the trucks were plugged into a working 120V outlet, they started every time.
With 1,200 trucks in the fleet all across the country, from a single truck warehouses to 100 truck locations, getting the consistency in this process was the challenge.

Has some engine fires with the Fords when plugged in. Turns out the block heater cords need to be inspected for wear, as they would fray and cause short circuits and then fires, when plugged in.
Added a block heater cord inspection requirement on the PM cycles and the problem went away.

Back in the day of carburetors I always installed a lower radiator hose heater, not the best but it did help and warmed up the cab quicker. We even used dip stick heaters on the smaller tractor.

And lots of cans of Heet.

I knew a guy that used a dip stick heater on a air cooled VW back in the 80's.
