I have seen many frost plug engine block heaters, and they usually look something like this
While changing anti-freeze last weekend, l found this item piped into the heater hose.
My first guess was some kind of auxiliary "aqua-coil" ? Obviously, l needed a second guess.
Anyhow, thanks to 73explorer and redroad and sbilby123, and especial thanks to 5851a, who identified this as an external engine block heater.
...indirectly, because--more precisely--its an external engine coolant heater: like this...or something similar

l'm a bit confused as to how this works and how well it circulates the coolant, warms the block, etc.
Next l'll need to inspect it more closely for a part number, watt rating or any other identifying marks on the outer shell.
So l'm soliciting comments; anyone with any information, experience or other suggestions about this accessory, please feel free to add it here.
We really need all the help we can get up here in Northern BC. Especially since Cooter's canvas carport is not heated.
Thanks everyone, and bundle up! lt was -4*C this morning, and there's rain in the forecast.

They were usually around 1500 watts. they use coolant from bottom of block hose, the warm water rises and as it cools in goes down. If below 0 would be best plugged in all night. Make sure you have good heavy cord and clean terminals on plug ins. They did work back in the day.
5851a: thank you sir, that's a lot of good information. Yup. we usually leave the regular block heaters plugged in overnight when temps are forecast below zero.
John89: yup l saw that style when l was googling this one. l also found a magnetic block heater but the one that intrigued me most was the dipstick style oil heater.
Helping a friend excavate a cattle tank this week so l'll try to get a closer look at mine this weekend. Finding this block heater is actually a pleasant surprise.
Years ago I worked for a large utility company near Toronto. They used that type of block heater on a lot of their trucks. They seemed to work quite well. I do believe I still have one buried in my spare parts.
People are funny, eh?
