I bought my DK45 in 2006 and it came with a block heater. The plug in is on the left side just forward of the cab. I plugged it in a couple of times the first winter, but haven't done so since...it seems to start up just fine without it. Minus 20 C (a few degrees below zero F) or so is about as cold as it gets here, though.

-20F for the record... Doubt mine came with the heater the dealer I had was a moron. I had asked for a list of all the options and to be able to choose from dont remember that being avaialble from the list... I would have taken it if it was. is the plug outside the cowel or in the engine compartment?
