The purpose of the vehicle to pressurize the cooling system
The function of the cooling system is to make the engine in any working condition are moderate cooling, so as to maintain the appropriate temperature (coolant temperature) to work.
When the coolant temperature below 80 ℃, the paraffin into a solid, the spring will be pressed on the valve seat, the valve closed, the coolant from the bypass flow into the air conditioning radiator inlet pipe into the radiator, that is, small cycle, The cooling intensity is small. When the temperature of the coolant is higher than 80 ° C, the paraffin wax melts into liquid and its volume expands, forcing the rubber sleeve to shrink, the upper end of the counteracter rod can not move up due to fixation, the rubber sleeve moves the shell against the elasticity of the spring, Valves, most of the coolant can enter the radiator along the radiator into the radiator for a large cycle, a small part of the coolant is still a small cycle, cooling system cooling strength increases
The engine cooling system consists of radiator cover, radiator, storage tank, hose, water pump, fan, thermostat (thermostat), cylinder and cylinder head and intake manifold
