Working principle The main function of the auxiliary kettle (expansion tank) is to store the coolant and adjust when the pressure of the cooling system is too high or too low. When the cooling system pressure is too high, excess coolant will flow into the auxiliary kettle; When the pressure is too low, the coolant in the auxiliary kettle will flow back to the cooling system, thus keeping the pressure of the system stable
Maintenance considerations include:
Check the liquid level regularly: ensure that the liquid level is within the normal range, and replenish the coolant in time.
check the tightness : start the engine, observe whether the auxiliary water tank and pipeline leakage phenomenon, if there is leakage should be dealt with in time.
maintenance : Check the status of the auxiliary water tank regularly, replace the damaged parts in time, and keep the cooling system clean and normal
