sidenote to this thread, not to derail it, but what are those rubber pieces connecting the two hardlines called? if you look at D45 pics you can see what im talking about there is a third one of those towards the back of the block and mine is leaking some antifreeze out of it... hard spot to get to and im not sure what those little rubber hose pieces are called?
What happened to just plugging it in and leaving it be? :what: I would think the block heater would be plenty assuming the element is still good.
