How to Deal with the Zizzing Sound When Accelerating?
2 Answers
There could be several reasons for the zizzing sound when accelerating. 1. Aging throttle cable: You can lubricate it with some waste engine oil. 2. Mechanical wear between the throttle pedal: Similarly, lubricate it with waste engine oil. 3. Possible increase in free play: Just adjust it at a repair shop. 4. Clutch wear: If the sound is coming from the clutch, then the clutch wear issue should be considered. When you press the accelerator, the vehicle works but doesn't deliver power, which is a slipping phenomenon. It is mostly due to the thinning of the clutch plate. If there is a rustling sound, it is likely that the clutch release bearing is damaged. It is recommended to have it checked at a repair shop.
There is a hissing sound when accelerating, and I think it's very likely due to a belt issue. The belt may be worn or loose, causing it to slip and make noise when the engine runs at high speeds, such as the alternator belt or power steering belt. I've encountered this multiple times while working on my car. You can start by opening the hood and simply checking the belt for cracks, aging, or excessive looseness. If any issues are found, replacing the belt should solve the problem. However, if the noise persists after replacement, it might involve deeper problems like a damaged water pump or alternator, requiring inspection by a professional repair shop. Regular maintenance should include cleaning and lubricating the belt, as well as adjusting its tension periodically to avoid issues while driving. Small faults left unattended can lead to bigger problems, such as belt breakage causing vehicle breakdown, which would then incur higher repair costs. Therefore, any unusual noise should be taken seriously. After a simple DIY inspection, it's advisable to have a technician use professional tools for a definitive diagnosis to ensure safety.
