摘要
Various systems and methods are described for a cooling system coupled to an engine in a vehicle. One example method comprises, during engine off, operating an auxiliary pump to flow coolant through a heater core; and, during engine running, operating an engine pump to flow coolant through the heater core and radiator, and selectively operating the auxiliary pump to assist flow through the heater core based on operating conditions.
