If the shutoff valve isn't, the core will get warm. Otherwise I don't think
the engine will influence things much. However, the rear heater never gives
you fresh air under any circumstances, it just sucks it in from the sides
and blows it out the front; so it will never be cooler than cabin ambient.

The shut off valve is in the off position, according to the manual.  I tried
it in both positions though, and as I said, basically got hot and warm air,
depending on whether the valve was on or off.  And then a day later I ran it
again, and the air still felt warm.  But, since the unit does not draw air
in from the outside, maybe it was blowing the already warm air in the van.
In any case, the air is noticeable when the fan is on, as it is warmer than
the rest of the air in the vehicle.  Oh well, sweatin' to the oldies I
guess.
