Buying the heater separately?
Ask your installer whether they supply the part. If you need to buy it, start with your exact vehicle and engine. A factory-installed heater may only need a matching replacement cord.
Only missing the cord?Yellowknife is the coldest city in Canada — January mean lows near -30°C and stretches below -40°C every winter. Unplugged vehicles simply do not start. Every parking lot has power, every vehicle has a cord, and many run a block heater, oil pan heater, and battery blanket together on a three-way splitter.
Above the 60th parallel, engine pre-heating is a safety system. Locals also fit winter fronts over the grille and leave vehicles idling in deep cold — practices that raise eyebrows down south and save engines up here.

A practical winter setup for Yellowknife
A removable magnetic heater avoids an installation appointment when the engine has a flat steel pan. Pair it with a timer and a properly rated splitter; magnetic heaters do not stick to aluminum or composite pans.

What a Yellowknife shop will be quoting on
Install cost tracks the engine, not the city. Check the heater type and part numbers catalogued for your model before you call around — it is the difference between a one-hour job and an afternoon.
