I've been reading a few of the comments in this thread and it seems that many just plug in their block heaters when it gets 'cold' in their locale. Cold...hot...etc..is all a relative thing of course and we usually determine if it's cold/hot by our personal experience.
Often many places in North America don't really get cold enough for the block heater to engage. I know GM factory block heaters installed on their gas engines...don't operate until the temperature reaches -18 Celsius or 0.4 Fahrenheit. One thing to remember is that eventually when the temp reaches -40 C....the Fahrenheit equivalent is also -40 F.
Back to the subject at hand. I don't know if their diesel engine block heaters cut in at certain temperatures or different temps than GM gas engines.
I would advise owners of any make of gas/diesel engine check their operators manual to determine if factory installed block heaters are controlled by temperature. If they do, you may well be plugging in to no avail, if your areas climate does not get really cold, as determined by the factory when it comes to the operation of their block heaters.
