How to Deal with Excessive Noise in Cruze?

[DelaneyLee]

If it is during the break-in period, loud noise is normal, and try to avoid driving with high throttle. Outside the break-in period, it is necessary to check for any internal engine wear, and switching to better engine oil may help. Here are some relevant information: 1. If the engine noise is loud, it might be due to poor engine lubrication, in which case the engine oil needs to be replaced. It is recommended to use fully synthetic oil. 2. If the exhaust noise is loud, the solutions are: (1) The simplest method is to insert a steel wool ball, the kind used for washing dishes at home, which can significantly reduce resonance caused by exhaust quality issues and also has some sound-dampening effect. (2) Change the diameter of the exhaust pipe, which requires welding. (3) Modify the mid-muffler, either by replacing it with a sound-dampening mid-muffler, altering its structure, or adding more metal sound-dampening materials inside. If the air conditioning fan noise is loud, the solution is: simply replace the fan or lower the water temperature.
