How to Eliminate Car Engine Noise?
2 Answers
Methods to eliminate car engine noise are as follows: 1. Loose engine mounts: It is necessary to inspect and tighten the engine's mounting components. 2. Loose plastic parts in the engine compartment: Confirm through inspection that the noise is emitted by plastic components and adjust by tightening them. 3. Loud engine noise during cold starts: After prolonged parking, the car may produce louder noise upon starting. This is because the lubricating oil has all flowed back to the oil pan, and the engine is not fully lubricated, which is a normal phenomenon. The noise will disappear once the car starts and runs normally. 4. Insufficient tension of the engine belt: The tension of the engine belt needs to be adjusted promptly.
I've been driving old cars for many years and have some good tips for dealing with engine noise. First, check the oil level and quality - when the oil is low or too dirty, the engine will make squeaking sounds, and changing the oil promptly can immediately reduce noise. Next, inspect the belt condition - aging cracks can cause whistling sounds, simply tightening or replacing the belt is an easy fix. Don't forget the air filter - clogs will increase intake noise, just clean or replace it. Loose mounting screws may also cause rattling sounds, try tightening the brackets with a wrench. Unlubricated fan bearings will hum - spraying some lubricant solves this. Avoid sudden acceleration and prolonged idling in daily use - this reduces internal wear and prevents noise buildup. These small steps can be DIY solutions that are cost-effective and efficient. Pay attention to daily sound changes for early maintenance.
