Heaters

The heating and ac The heating in a car is operated by the heater motor which uses part of the coolant. The latter heats up whilst flowing through the engine. The heat is then used by the heater motor as heating for the cabin area. The air conditioning works with car parts including the ac compressor, the condenser and the ac filter. As opposed to the heater, the ac does not use coolant, but air conditioning gas to cool.
