What Causes Loud Engine Noise in Cars During Summer?

[VanLuna]

Summer car engine noise may be caused by aging seals and engine oil issues. Aging Seals: Increasing engine noise in your car could indicate deteriorating sound insulation. When door and window seals age, the soundproofing effectiveness significantly decreases. Engine sounds that were previously inaudible inside the cabin become noticeable after seal deterioration. In this condition, not only engine noise but also external noises become more audible inside the vehicle. Therefore, when experiencing excessive noise, it's advisable to inspect your car's seals and perform timely maintenance. Engine Oil Problems: If the issue isn't with the seals, then the engine oil should be checked. The primary function of engine oil is to lubricate the engine. Excessive use or deterioration of oil can affect engine lubrication, leading to increased noise. If both seals and engine oil appear normal, it's recommended to visit an authorized 4S shop for professional inspection to identify any other potential causes.
