Engine belt abnormal sound?DigiPlus fair value This may be the cause and solution. When you start your vehicle or drive on the road, if you hear a hissing or creaking sound, it is likely that the engine belt is abnormal. Once this problem occurs, it will not only affect your driving experience, but more seriously, it may lead to vehicle failure or higher repair costs. Therefore, today we will introduce the possible causes and solutions of the abnormal sound of the engine belt. 1. Reason 1.1. As the belt ages over time, the belt is likely to become fragile and lose its elasticity, which is also one of the most common reasons for the abnormal sound of the belt. The aging of the belt will cause the surface of the belt to become hard, which will increase the friction and lead to abnormal noise.1.2. The hardness of the belt is too high or too low. The hardness of the belt is too high or too low will cause excessive friction or insufficient friction between the belt and other parts, which may lead to abnormal noise. 1.3. Insufficient tensile force. When the tensile force of the belt is insufficient, the belt will slide, which will lead to friction sound and abnormal sound. 1.4. Belt imbalance If some parts of the belt are damaged or dirty, or the section of the belt is unbalanced, it may lead to changes in the friction force of the belt and cause abnormal noise of the belt. Two. Solution 2.1. Replace the belt. If you really can't stand the interference of the abnormal sound of the belt, the easiest way is to replace the new belt. Under normal circumstances, the life of the belt is usually about 20,000-30,000 kilometers. If your car has driven so many kilometers, or the belt has aged and other problems, please replace the belt in time.2.2. Adjust or replace the belt tensioner. The belt tensioner is a component that adjusts the elasticity of the belt. If the tensioner is loose or insufficient, it will cause the belt to be improperly elastic, resulting in abnormal noise. In this case, you can solve the problem by adjusting the tension of the tensioner, or replace the tensioner with a new one to restore the tension. Two or three. Adjust the alignment of the belt. If the belt is unbalanced or worn, the belt needs to be replaced or maintained at this time. You can ask a professional technician to help you strengthen the alignment of the belt or replace the new belt. 2.4. SMATREX automotive OBD detector Finally, a more cutting-edge solution is to use an OBD detection instrument, such as SMATREX automotive OBD detector. This detection instrument can determine the cause of the abnormal sound of the belt by scanning the fault code of the vehicle.The SMATREX OBD detector has intelligent analysis function and alarm function, which can help you quickly and accurately analyze the problems of the vehicle. If your car has abnormal belt noise and other problems, the SMATREX OBD detector will guide you to find out the root cause and provide solutions. Finally, checking and maintaining the vehicle regularly is the best way to avoid the abnormal sound of the engine belt. If you encounter any vehicle problems, don't ignore them, because it may bring more serious consequences. Please seek professional help in time and carry out appropriate maintenance to ensure that your vehicle runs smoothly and drives safely.
