I'm confused now! I though that a block heaters function was to primarily heat the oil?
That's what I was always told at least..... When it's -56 with the windchill noting it going to keep the coolent warm.

Thanks everyone for your help!

As I was thinking about this, I realized that since I bought the bus in October, I've only started it a few times, just to move it in or out of the driveway. It probably never ran enough to charge batteries. In addition to being in the single digits, the batteries were probably kind of low, then I ran the coolant heater for an hour or so.

It sounds like the coolant heater, when running off of the batteries, should be used to supplement the heat and not really to keep it warm for starting.

You're thinking of an oil pan heater. They can come in a mat that sticks to the underside of the oil pan and will evenly heat the oil by convection.

The block heater on my T444e made starting much easier in some -40C weather last winter, just before I ran away from the cold
