How to exhaust JAC Ruifeng when changing antifreeze?

After replacing antifreeze, start the vehicle and wait for the cooling fan to rotate, because after the cooling fan rotates, the thermostat in the engine cooling system is completely opened. At this time, check the water level of the auxiliary kettle. If the water temperature of the auxiliary kettle is lower than the minimum scale, add it to the normal scale.

Most of the water cooling systems used in automobile engines use water pumps to force coolant to circulate in the cooling system, which is generally called forced circulation water cooling system.

The cooling water jacket is cast on the cylinder head and cylinder block of the water-cooled engine. The water pump sucks the coolant from the radiator and pressurizes it to the water jacket of the cylinder block. The coolant absorbs the heat of the cylinder block, the temperature rises, and then flows to the cylinder head water jacket. After cooling the cylinder head, it flows from the thermostat at the top of the cylinder head to the radiator. Due to the strong suction of the electric fan, air passes through the radiator at high speed from front to back, so the heated coolant flows through the radiator. Heat is constantly dissipated into the atmosphere, thus cooling the coolant. After the cooled coolant flows into the sewer cavity of the radiator, it flows back to the engine under the action of the water pump, so that the parts working at high temperature are continuously cooled.
