How to Use the Engine for Heating While Driving in Winter?
2 Answers
In winter, the way to use the engine's heat for heating is to turn on the air conditioning's warm air. Principle: When the car's air conditioning is heating, 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 the air conditioning vents to blow warm air. Instructions for Using the Car's Air Conditioning Warm and Cold Air: Warm Air: It is best not to turn on the warm air immediately after starting the engine. Cold Air: 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.
Keeping warm while driving in winter is actually quite simple. I personally rely on the engine's heat to get through the winter. After starting the car, don't drive off immediately—wait three to five minutes for the engine temperature to rise so the heater works effectively. Then press the AC button, turn the dial to the red zone for heating, and set the temperature to the highest, around 28°C. Set the fan speed to medium or auto mode, and choose recirculation mode for quick warming—the cabin will soon feel cozy. Remember to regularly check the coolant level and inspect the heating system for leaks, as antifreeze is crucial in winter. Once, I neglected this and ended up with no warm air halfway, leaving me shivering. Safety-wise, using warm air to defrost the windshield helps clear fog and prevents blurred vision. Avoid forcing hot air when the engine is cold—it wastes fuel and harms the engine. Make it a habit to check these before every drive.
