Happy New Year! So, we have passed solstice and swapped out our old calendars, so Old Man Winter has seen fit to hit us with a vengeance! He has been a little hard on us lately, dishing out temperatures as low as -43 C. We had a snappy little cold snap that lasted several days (see below). For those who don’t know, that kind of cold — anything approaching -40 — is extremely hard on vehicles and machinery.
Our fun began when we noticed how rough the car was starting, despite being plugged in. Let me offer an explanation for my southern friends and followers: “Plugging in a vehicle” actually means plugging in a heater of some sort — usually an engine block heater — which gobbles up electricity in order to attempt to keep the vehicle “warm.” I know I’m overusing “quotes” and I don’t care! “Warm” is a relative thing. When it’s well below zero, the oil which is meant to lubricate the engine and allow it to turn freely and not grind itself into pieces gets really thick. When it’s -40C, it’s most jello than liquid. This makes the engine very slow to turn over and your battery has to work extra hard to get it to turn over enough times to start. it’s a blast, really, to count how many times the engine will roll over before starting — I think the record for my car is 12 times. But it started! So, back to the story.
It was about -25C or so, and although the car had been plugged in, it sounded really rough starting. This led us to think there might be something wrong with the block heater. The obvious weak points are the power cord, plug in, and extension cord, but these all checked out fine. Since my husband is such a snazzy, smart guy, he tested the resistance in the circuit — seemed fine, but this isn’t an indicator of power flowing, just that there is no clear break in it somewhere. A further test was needed, to check how much current was flowing. I helped by holding ends of wires from the multimeter (a device for testing circuits) to the extension cord end and the block heater plug… not the kind of thing you should EVER try to do if you don’t know what you’re doing! Suffice it to say, we discovered that the block heater must be dead.
Drat. Well, what can you do? Start finding out how to get a new one, or look into buying an oil pan heater instead. Oil pan heaters are easier to install than block heaters, and apparently work just as well, or even better, since they heat the oil directly and keep it from becoming jello. Mmmm! 10W-30 jello, my favourite! (Just kidding!)
Long story somewhat shortened, we couldn’t get one very easily. We would have had to buy it over the phone from Yellowknife and get it shipped in by plane, or get a friend in High Level to buy one and then find someone driving north who could bring it. We brainstormed what to do… and then I remembered that I have a buddy heater! It had belonged to Peace Air, before they went out of business, and it’s a great little heater. Pilots put these heaters inside the engine cowlings on planes to keep the engines warm, and they produce quite a bit of heat for their size — not as intense as a hair dryer, but not far off. The best part of all is that they are meant to operate outside, for hours, unsupervised. Perfect.
So, the trick was to figure out how to get the heat to the engine. We quickly figured it would work pretty slick to slide the heater under the car and put cardboard around the bottom of the car to keep the heat in. Well, when we got to it, we ended up making use of the plentiful firewood and piling snow around the car on the sides. We tried to position the heater directly under the oil pan, and considering that the it’s not quite as cold out (only -25C) and there isn’t much space below the car to heat, I think it’s going to work!
So, that’s just one of many adventures we had over the Christmas season! The others involve repairing a block heater plug in -25C (wearing gloves as much as possible!), a malfunctioning defrost heater (or any sort of internal heat), and a truck that wouldn’t start. It might be the starter solenoid, or the starter, or maybe it just couldn’t face the -40′s.
This blog post is dedicated to my friend Jim, and ALL the men and women who maintain our winter roads — grader operators, plow truck drivers, sanding truck drivers, and all the other operators! You rock. I know you work hard to keep our roads passable, and believe me, we “regular motorists” appreciate it! Take care out there.
