Basic Role Drive coolant for engine heat dissipation

In the car engine block, there are a number of waterways for cooling water circulation, and placed in the front of the car's radiator (commonly known as the water tank) connected through the water pipe, constituting a large water circulation system, in the engine on the water outlet, equipped with a water pump, driven by the fan belt to drive, the engine block waterway within the hot water pump, the cold water pumped in. Next to the water pump there is a thermostat, the car just started (cold car), do not open, so that the cooling water does not go through the tank, only in the engine cycle (commonly known as small cycle), to be the temperature of the engine to reach more than 80 degrees, open the engine hot water is pumped into the tank, the car forward when the cold wind blowing through the tank, take away the heat, roughly this is how it works.
