Abstract
When a truck engine () is not running, an auxiliary coolant heater () can heat engine coolant and pump it through an occupant compartment heater (). A coolant flow control system (), including a valve assembly (), associates the auxiliary heater () with both the occupant compartment heater () and engine () for selectively distributing heated coolant. When engine () has been running and is shut off, auxiliary heater () can be turned on and valve assembly () operated for occupant compartment heating while keeping the engine () warm. When the engine is cold, the auxiliary heater can be turned on and the valve assembly can be operated for engine pre-heating prior to starting.
