Where is the drain of Ruifeng s2 water tank?

It is located at the bottom of the vehicle water tank. After the engine antifreeze is discharged, the vehicle needs to be cooled for about an hour to avoid scalding. After the water outlet is opened, it is necessary to turn on the switch on the water tank and the switch on the antifreeze kettle, so that the antifreeze can be put more cleanly, and at the same time, check whether there is any problem with the temperature collector of the engine. The radiator in the engine water cooling system consists of a water inlet chamber, a water outlet chamber and a radiator. The cooling liquid flows in the radiator core, and the air is outside the radiator core, and is cooled by the heat cooling liquid to the air. The cold air heats up because it absorbs the heat of the coolant, so the radiator is a heat exchanger. Million car purchase subsidy
