Abstract
A vehicle heater of the type that uses diverted engine coolant is provided with an accelerated warm up process that takes the coolant to a temperature suitable for passenger space heating more quickly. The fan that normally pulls outside air through the front end grill is, after vehicle start up, run in reverse, so as to actually retard the flow of air through the grill. The net effect of a separate structure that physically blocks air flow is achieved merely by using existing components in a new way.
