How can I unblock the car heater tank when it is blocked?

If the car heater tank is blocked, it can be blown by high-pressure air. It is relatively simple to remove two pipes from the heater pipe and then blow through the heater tank. The reasons for the blockage of the warm air tank are as follows: 1. It may be that the engine water channel is dirty all the time, which causes the blockage of the warm air tank; 2. If antifreeze has been used all the time and replaced at the specified time, this phenomenon will not occur; 3. The warm air tank is a device for providing warm air for air conditioning in winter, which uses the heat continuously circulated in the car by the temperature of engine cooling water to provide heating.
