How to wash the small heater water tank in Chery QQ car

First of all, the heater water tank is in the cab. If you want to flush it, you need to remove it first.

If you just flush the engine water tank outside, it is okay, but the premise is that the engine is cold. If it has just been started, it is recommended not to flush it immediately.

Also, during the flushing process, the water should be adjusted to a mist state, otherwise it will knock down the radiator and the heat sink, resulting in poor heat dissipation performance.
