Why is the engine noise loud in GAC Trumpchi vehicles?
2 Answers
GAC Trumpchi engine noise may be caused by increased carbon deposits, poor sound insulation, low coolant temperature, or shock absorber issues. Increased carbon deposits: Carbon deposits accumulate as old engine oil becomes thinner with use. Thin oil tends to leak, leading to more carbon deposits and power loss. When new oil is added, the engine may struggle to adapt to the oil viscosity, potentially causing higher RPMs and increased engine noise. Poor sound insulation: If the noise is only noticeable inside the car, it indicates poor sound insulation. In this case, check for aging seals or improve the vehicle's sealing to reduce noise. Low coolant temperature: When the coolant temperature is too low, it may result in loud engine noise. Therefore, coolant should be checked and replaced regularly to prevent other potential issues.
As a seasoned owner of several GAC Motor vehicles, I've found that the loud engine noise mainly stems from two reasons. Firstly, GAC's engine design may prioritize performance and durability over sound insulation. Like some budget models that cut costs, the hood or soundproofing materials might not be sufficient, allowing wind and mechanical noises to penetrate easily. Secondly, inadequate maintenance can amplify the noise. For instance, using degraded engine oil for too long or having a dirty air filter that blocks intake can cause the engine to roar under heavy load. I personally experienced this once – after changing to fresh oil, the noise reduced significantly. Additionally, driving habits play a role. GAC's power tuning leans towards sportiness, so aggressive acceleration naturally produces more pronounced engine sounds, but this isn't a defect – you'll get used to it. Regular maintenance can alleviate this issue, especially checking for loose belts and screws.
