How to judge that the heater water tank is broken?

How to judge whether the heater tank is broken? How to judge whether the heater tank is broken? The broken water tank shows: water leakage, reduced circulation capacity, abnormal noise, and idling of the car. 1. Water tank leakage is easy to find. A small amount of water leakage will be found at the exhaust port of the water pump, and a large amount of water leakage can directly leak to the ground through the chassis. 2. Open the car water tank, and you can see that the coolant is in a vortex shape. If the vortex is not obvious, it means that there is something wrong with the automobile water pump, especially in the high temperature environment in summer, the water temperature will rise. 3. If the water tank is broken, the car will make abnormal noise, generally it is the problem of the water pump bearing, so pay more attention. 4. Because the automobile water pump is connected with a belt to collect the cold water in the water tank, if the rotation of the water pump is affected, it will directly affect the work of the engine, and it is prone to unstable speed, which mostly happens in winter. If the engine water tank is used for too long, it will easily lead to problems such as rust and scaling, which is very common. Rust and scale will limit the flow of coolant in the cooling system, reduce heat dissipation and cause certain damage to the engine. The water tank should be cleaned regularly, especially the details, to ensure the normal operation of the engine and prolong the service life of the engine. @20 19
