How to solve the problem that Santa Fe 1.8t heating water tank does not return water?

I. Reasons

The water tank or water pipe joint leaks, resulting in water shortage (air) in the water tank and poor circulation. Water flows to the standby kettle after high temperature and high heat, and cannot be sucked back by the water tank after cooling.

Second, the solution

1, check whether the water tank is short of water on time.

2. Check whether it is blocked.

See if the suction pipe between the auxiliary water tank and the water tank is blocked (because the water temperature is high and the steam pressure is high, the backwater suction pipe may not be connected)

3, water tank exhaust

Let the car idle, and then slowly add water until there is no air in the water tank.

4, adjust the pipeline slope

See if the position of the auxiliary water tank is low, because the auxiliary water tank of some cars is aging for a long time, the hook is not tight, and it often slides down, resulting in the auxiliary water tank being not high enough and the pressure is not enough. If there is no problem, the water tank cover has been replaced. We can only see if the water outlet in the water tank is blocked by water stains. Try changing the water tank.
