How to Use the Engine for Heating While Driving in Winter?

[AsherDella]

In winter, the way to utilize engine heat for heating is to turn on the car's heating system. Principle: When the car's air conditioning is in heating mode, the high-temperature coolant from the engine flows through the heater core. At this time, the air blown by the blower also passes through the heater core, allowing warm air to be emitted from the air conditioning vents. Instructions for using car air conditioning heating and cooling: 1. Heating: It is best not to turn on the heating immediately after starting the engine. 2. Cooling: After turning on the cooling function, the engine drives the compressor to operate, allowing the compressor to continuously compress the refrigerant and deliver it to the evaporator.
