I live in Massachusetts so our temps can get down that low too regularly. Never needed a heater for gas engines. This Ranger started up fine last winter first key turn or remote started for work runs during the week. I could see it if we got -30F temps as a norm.
Now if you’re running a diesel I can see it. No questions there!

I had block heaters on my Diesel trucks. In case some may not know, they are meant to be plugged in overnight and not just used as an "instant" heater right before starting the engine in the am. It would have to be really cold as in substantially below 0 F for them to be needed in a gas engine.

I'm sorry but that simply isn't true of our vehicles. From the Owner's Manual

This is why they should be on a timer

Update...

today the heater element and wire as. arrived.

I was alarmed at how long the wire as. is - 8 to 10 ft. I called my dealer and suggested they contact one of their partner dealers in the north that may have a Ranger on their lot with a block heater, and to send photos of how the wire as. is routed from the factory. They could also contact Ford Tech Support for this information but at any rate, the tech isn't going to stumble his way through the installation and get the routing correct.

Another thing that surprised me was the rating on the heater element. 400 watts at 115 volts. This means the heater element would only draw 3.5 amps from a std household outlet. After giving it some thought, the heater element is only trying to heat 12 qts. of coolant. So I guess it is sized properly.

I think this might work for you as well. Rather than between $80 and $118 for the plug and as much as $200 for the cord, it is probably worth a shot. From that service manual post above, it looks like the install is fairly straight forward. Just be sure you get the proper antifreeze and antifreeze/water ratio when you refil.

My comment stands correct as written. They are meant to be used over night and in extremely cold conditions. The heater will keep the engine warm as the heat is continually dissipated by the ambient air.
Notice the phrasing from the manual "....approximately 3 hrs" and "0.4 - 1.0 kW-hrs"
Run it for 3 hrs unplug it and in a few hrs the engine will be cold again, its basic thermodynamics.

Did you even read my post that says to put it on a timer so it shuts off just before you're ready to start the vehicle? No time for the coolant to "cool off".

I don't need one but if I did I'd want to use a timer to turn it on 3 hours before I leave in the morning.

Try it but if you do use a timer be aware it may not be able to handle the current draw.

Step 3 of installing the heater element is to remove the fender splash shield. This is the same shield that is removed to R&I the engine oil filter. This splash shield is held in place by several plastic rivets which over time can become hard, brittle, and break. I ordered some extra rivets just in case any get broken. Part # for the rivets is W715694-S300 and is packaged as qty 1.

Lastly, if you're doing this job yourself you going to need to order some of the yellow coolant for top off - either concentrated (VC-13-G) or prediluted (VC-13DL-G).

We usually get 10 days at or below -10F here in N Illinois and I've never heard of anyone using a block heater on a gas engine, maybe a few hundred miles north of us. We have one on our Ram diesel and it regularly gets plugged in on those nights. We just plug it in at night if we know we are using the truck the next day and it's going to be very cold over night. I don't see any reason to have it on a timer to turn off before you are going to start the vehicle, you have to unplug it anyway, seems unnecessary.

I live not too far from you and it is less common these days. However, if you park outside or in an unheated garage, a block heater can be nice to warm up the truck a bit before you start it. That way you don’t need to start the truck with remote start to warm it up and burn the gas. They can work well for that. A lamp timer can work as the amp draw is low. Also an option if you park in a garage and therefore can’t start the truck to warm it up.

I don’t have one myself, but it is not an unreasonable thing to have.

...and if you're ordering the truck, option code 41H costs less than $100
