When engine works, heated by the high temperature of the engine cylinder, the coolant is pumped 
into the heat exchanger through water pipe by the water pump of the cooling system. Air from 
blower can take the heat given off by the coolant into the vehicle or the windscreen to raise the 
temperature in the vehicle or defrost. After the cooling process in the heat exchanger, coolant is 
pumped back by water pump. Repeating the circulation can make warm air heating. See Figure
