The role of the automobile water pump is to pressurize the coolant to ensure that it circulates in the cooling system. Generally speaking, it is to let the water circulate continuously through the radiator engine cylinder body parts to take away the heat, so as to ensure that the engine is not high temperature.
In automobile engine cylinder block, there is a channel for cooling water circulation, and put in the front of the car radiator (commonly known as water tank) through the water pipes connected to form a large water cycle system, outlet on the engine, equipped with a water pump, driven by fan belt, within the engine cylinder block water heat pump, the pump into the cold.
Beside the water pump and a thermostat, cold (car), when the car has just started not to open, make the cooling water without water tank, only within the engine cycle (commonly known as small cycle), momentum motivation above the temperature of 80 degrees, is opened, the hot water is pumped into the tank engine inside, cold wind blowing tank when the car forward, take away heat, generally this is work.
