[back of envelope calculations thoughtfully provided snipped, suffice it
to say that there is a buttload (technical term) of hot air blowing
against the front of the cabin and under the body.]

Pity the radiator can't be mounted on the rear hatch with sufficient
ventilation to work so that the hot air would trail behind the van.
