When the engine temperature is normal, you can turn the warm air temperature to the maximum and turn the fan to the maximum. If there is no warm air, it is basically blocked.
Methods to prevent small warm air water tank from blocking;
1, keep the cooling water clean (don't add ordinary water casually, or use tap water in case of water shortage, which will cause scaling in the waterway), replace the cooling liquid every two or three years, or the cooling liquid is turbid, and clean the water tank waterway in time before replacing the cooling liquid.
2. Turn on the warm air twice a month in summer, so that the coolant can circulate through the warm air small water tank to reduce the scale blockage.
Extended data;
Maintenance method of warm air small water tank;
1, radiator should not be in contact with any acid, alkali or other corrosive substances.
2. It is recommended to use soft water and soften hard water before use to avoid internal blockage and scaling of radiator.
3. When using antifreeze, in order to avoid radiator corrosion, please be sure to use long-term antirust antifreeze produced by regular manufacturers and in line with national standards.
4, in the process of installing the radiator, please don't damage the radiator belt (film) and hit the radiator, to ensure the heat dissipation ability and sealing.
5. When the radiator is completely drained before adding water, turn on the drain switch of the engine cylinder first, and then turn it off when there is water flowing out to avoid blisters.
6, in daily use should always check the water level, stop using water after cooling. When adding water, slowly open the water tank cover, and the operator's body should be as far away from the water inlet as possible to prevent high-pressure steam from spraying from the water inlet and causing burns.
7. In winter, in order to prevent the core from being damaged due to freezing, such as parking for a long time or indirectly, all the water should be drained with the water tank cover and the drain switch.
8. The effective environment of standby radiator should be kept ventilated and dry.
9. According to the actual situation, the user should thoroughly clean the radiator core within 1 ~ 3 months. When cleaning, rinse with clean water in the opposite wind direction. Regular and thorough cleaning can prevent the radiator core from being blocked by dirt, which will affect the heat dissipation performance and service life of the radiator.
10, the water level gauge should be cleaned every 3 months or according to the actual situation, and the removed parts should be cleaned with warm water and non-corrosive detergent.
