What should I do if the water tank of the car heater is blocked?

First, we need to know the reason why the water tank is blocked. Is the pipe blocked? Or is the socket blocked? Or is it stuck inside? First find out the location of the blockage. As long as it's not blocked in the water tank, it's easy to do, just dredge the pipeline.

The simplest thing is to find a good car wash, and then find a repairman to remove the inlet and outlet pipes of the warm air tank, and then wash them back and forth with the water gun of the car wash until the water comes out.

If you get the scale remover, you can also put down the original coolant, add clean water and scale remover, rinse it with clean water several times after a day or two, and then inject new coolant.

If not, let's see if there is a shop that specializes in repairing water tanks. If there is, send it to the master of the water tank shop and see if you can spend a few dollars to clean it. If it works, then this water tank can be used for a period of time. For example, the master doesn't think it's necessary (this kind of small water tank is made of thin material, sometimes it is soaked in acidic cleaning solution, and it leaks after passing. So sometimes people don't want to do it. You have to buy a new one.
