Hoses exist in various parts of the car, each with different functions. However, hoses are easy to corrode, so the inspection and use judgment of hoses are also very important for car owners.
Hoses exist in various parts of the car, each with different functions. However, hoses are easy to corrode, so the inspection and use judgment of hoses are also very important for car owners. New cars are not considered for the time being, especially those that are more than six years old. If you have an old car, you should consider whether to have it inspected.
As a flexible pipe connection, coolant hoses are widely used in automobile pressure accumulators and auxiliary heat exchangers. In order to ensure that the coolant flows smoothly through the manifold and valve body, the coolant hose adopts a strange tree-shaped multi-branch sub-channel structure. The coolant hose must not only meet the requirements of function, structural size and performance, but also must ensure that it fully adapts to the complex and compact engine room layout.
The engine's high-temperature radiation and oil immersion can also cause the outside of the coolant hose to gradually age. The most common aging process is from the inside out. Therefore, when tiny pinholes appear on the outside, it indicates that serious corrosion has occurred inside the hose. This loss channel is the result of electrochemical corrosion and is a natural phenomenon of the micro-battery effect of the cooling system.
Oxygen in the air is one of the main factors causing this chemical reaction, so improving the filling process of the cooling system can effectively avoid such malfunctions. When there is a substantial leak of coolant, the fault is naturally obvious.
However, the key to the problem is how to diagnose the corrosion occurring inside the hose without disassembling it. The following method can help you quickly and accurately find the coolant hose that is about to end its life: knead the hose with your hands, especially the upper part of the radiator, bypass, manifold, valve body and heater hose, and its connecting end Ministry is the top priority. If the kneading area has a significantly softer or less elastic feel than other areas, it indicates that the hose there is severely corroded. If the vehicle's mileage is low at this time, it is recommended to check the voltage of its cooling system.
