After using a car for a long time, some problems are inevitable, such as feeling the engine noise increase while driving. Most people will think that there is an internal problem with the engine, but don't ignore that abnormal noise may also be emitted from the outside.
Therefore, when checking, we may first listen to whether the noise is coming from the tensioner. Although the tensioner is a small accessory, it plays a very important role in the timing system and accessory system. Why does the tensioner make a strange noise? What are the common faults of tensioning wheels
01. The function of the tensioning wheel
Tensioning wheel is used to adjust the tightness of the engine belt. Its main function is to provide necessary belt tension for the car belt and chain transmission system, and to prevent chain slippage to a certain extent, ensuring the normal and stable operation of the transmission system.
In addition, the tensioner also helps to extend the service life of the belt by maintaining appropriate tension and reducing wear caused by improper tension, thereby improving the efficiency and reliability of the entire transmission system. ‌‌
02. Common faults of automotive tensioner wheels
01. Make abnormal noise
When the tensioner bearings are damaged or poorly lubricated, abnormal noise may occur, and the engine may even experience timing jumps, affecting the normal use of the car.
02. Decreased spring force
The tensioning wheel is used to guide and tighten the timing belt or chain of the engine, always in the optimal tensioning state. Under normal circumstances, the spring force is very strong and cannot be twisted by hand. However, if it is easily twisted, it indicates that it is broken and will make a harsh noise when the car accelerates.
03. The belt cannot operate
The tensioner may get stuck in extreme situations, causing the belt to malfunction. This situation is usually caused by severe damage or wear to the internal components of the tensioner.
04. Oil leakage occurs
In addition to the belt tensioner, hydraulic tensioner may also experience oil leakage. Oil leakage not only renders the tensioner unusable, but may also cause corrosion of other components, thereby affecting the performance of the engine.
05. Fracture and deformation
If the tensioning wheel breaks and deforms, it may be due to improper operation during installation. The installation and adjustment of the tensioning wheel require certain professional knowledge and skills. It is recommended to follow the manufacturer's guidance for correct installation.
06. The tensioner does not match the belt
Using tensioning wheels or belts that do not match the original vehicle may cause performance issues, and components that match the vehicle specifications should be used.
