The coolant hose is widely used in pressure accumulators and auxiliary heat exchangers in automobiles. In order to ensure the smooth flow of coolant into 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 functionality, structural dimensions, and performance, but also ensure complete compatibility with the extremely complex and compact engine compartment layout.
Leaving aside the impact of design, the high temperature radiation and oil immersion of the engine can also cause the exterior of the coolant hose to gradually age. However, the most common aging process still occurs from the inside out. So, when tiny pinholes appear on the outside, it indicates that serious corrosion has occurred inside the hose. The wear channels are the result of electrochemical corrosion and a natural phenomenon of the micro battery effect in the cooling system. Oxygen in the air is one of the main factors leading to the occurrence of this chemical reaction, so improving the filling process of the cooling system can effectively avoid the occurrence of such accidents.

When there is a substantial leakage of coolant, the fault is naturally clear at a glance. However, the key issue is how to diagnose the corrosion inside the hose without disassembling it. The following methods can help you quickly and accurately identify the coolant hoses that are about to die: knead the hoses with your hands, especially the upper part of the radiator, bypass, manifold, valve body, and heater hoses, and their connecting ends are of utmost importance. If there is a noticeable softening or lack of elasticity in the kneading area (relative to other parts), it indicates that the hose has undergone severe corrosion. If the mileage of the vehicle is low at this time, it is recommended to check the voltage of its cooling system. During inspection, the negative pole of the voltmeter is connected to the ground electrode of the battery; Insert the positive electrode into the coolant (do not come into contact with any metal components). If the voltage reading is above 0.3V, a comprehensive and systematic inspection of the vehicle's grounding electrode is required. At the same time, it should be ensured that there is no auxiliary grounding electrode connected to the radiator bracket.

Treburg's industry-leading position is based on advanced polymer technology and extensive professional application knowledge
For soft tube channels, even if only one branch leaks, it is wise to replace the entire coolant hose, otherwise it will only result in half the effort and losing the big picture.
Although most hoses can be flexibly installed without twisting, almost all hoses still use the molding process because molded hoses are more suitable for compact installation spaces.
