I have to agree with NGM... are you sure there is a block heater? It is bitchin to do without one.
When I moved from the Prairies to the Maritimes, I never much thought about my block heater. That was until the temp dipped way down below freezing.
I went out and plugged my mini van in, just like I did when I lived out west. My next door neighbor's kid came out the next day and seen the power cord and wondered what it was like to drive an electric car.
