Why is the heater not hot?

Pacific Auto Network 1, heater water tank blockage: The heater water tank blockage of an automobile is one of the common faults when using warm air in winter. The heater water tank of an automobile is a scaled radiator of the engine water tank, which is as easy to block as the radiator of the water tank. Therefore, it is necessary to pay attention to the blockage of the heater water tank during use, which leads to the slow speed of coolant, reduced flow and insufficient heat, resulting in the heater not being hot.

2. The cooling system lacks coolant: coolant is an indispensable medium in the cooling system. When in use, the warm air circulation is a pipeline connected in parallel in the small circulation pipeline of engine coolant, which is connected with the warm air water tank. If the cooling liquid is insufficient, it is inevitable that the warm air is not hot, which is a relatively easy fault to solve.

3. thermostat failure: the most common failure of thermostat in heating system is that it can't be closed, and the water temperature will be low during use. The heating effect is naturally not obvious when the water temperature is low. If it is found that the water temperature is too low, it needs to be handled in time to avoid the situation that the oil consumption is too high and the wear is aggravated due to the low water temperature.

Note: When the seasons alternate, the owner needs to check and maintain the heating system of the car, so as to avoid abnormal smell during use and affect the normal use, especially the cleaning of the pipeline. If it is not used for a long time, it may breed bacteria and affect your health.
