Yukon Territory, near where the coldest temperature for North America was recorded.
For about the same cost, adding the double cardan CV joint front driveshaft was a much more worthwhile investment.

Note: Be sure to switch your controls to Defrost and maximum heat for good circulation.
I just installed a 1500W circulating heater on a 1991 HDJ-81 with 1HD-T. The PO had done an ASCD delete so there was an existing 3/8" hose on the block for me to cut into. I basically tee-ed into that and connected the heater inlet with a 5/8" hose.
For the heater mount I used the hose support bracket connected to the fuel filter support (took it off and drilled the bracket to suit the cheapo heater mounting strap.) Ran the outlet hose into the heater return from the firewall.
Here's a couple pictures... (EDIT: ran circ. heater for 20 mins at -20C and engine then idled right off - BIIIG difference!)
