Why Does the Engine Sound Louder After Driving Through Water?
1 Answers
After driving through water, the engine may sound louder due to water entering the bearings of the engine belt, causing corrosion and poor contact, which affects signal transmission and operation. Below are the reasons for increased noise after a car has driven through water: Lack of Coolant: The main function of coolant is to dissipate heat by circulating, carrying away excess heat generated during engine operation. Insufficient coolant can lead to higher water temperatures and increased noise. Aging Tires: Tires, made of rubber, harden and age over time, producing noise. Especially on poor road conditions, the noise transmitted into the cabin can be as loud as thunder. Additionally, the tread grooves gradually wear down, and many fine cracks appear, which is another reason for increased noise and also affects driving safety. Excessive Carbon Buildup: Car noise, apart from the mechanical sounds from the engine block, also includes noise from the intake system—high-speed gases passing through the air filter, intake pipe, and valves into the cylinders, creating aerodynamic noise during the flow process. This is particularly noticeable when there is carbon buildup in the engine cylinders. Therefore, it is advisable to clean carbon deposits regularly.
