So can you use and aftermarket block heater, with a GM cord end? Seems like a round about way to do things. Up here in Southern Ontario, I didn't opt for the block heater. If we get 1 or 2 nights where it hits -18*C, that is a COLD winter. The coldest we've had this winter so far is -17*C, just last week. By the time my wife has the kids up and ready to go out anywhere, its usually 9:30am at the earliest, so by then its usually warmed up a few degrees. Today it was -1*C.
