What Causes Abnormal Noise on the Right Side of the Engine?

[KingstonLee]

Reasons for abnormal noise on the right side of the engine: 1. Prolonged parking of the car leading to cold start noise; 2. Noise caused by unsuitable engine oil; 3. Noise due to improper belt tension; 4. Poor fuel quality or incorrect fuel grade causing noise; 5. Loose engine components leading to noise. Solutions: 1. Replace with suitable engine oil; 2. Adjust the tension of the engine belt; 3. Clean carbon deposits from the valves and adjust the valve timing; 4. Use the correct fuel grade or high-quality gasoline; 5. Inspect the intake and exhaust pipes and replace them if necessary; 6. Tighten or adjust the screws of the engine underguard.

Last time I was driving, I noticed an abnormal noise coming from the right side of the engine, like a continuous small sound. It's probably an issue with the belt system. If the belt is too loose or worn out, it can make a squeaking noise, while bearing wear produces a humming sound—it might be the generator or water pump bearings that are damaged. I remember my friend's car had a failed water pump bearing, which caused severe noise, and the problem was solved after replacement. Another possibility is a loose or unbalanced pulley, causing friction noise. The inspection method is simple: open the engine hood, listen for the noise location at idle, or gently shake the components to check for looseness. Safety is important, so address it early to avoid bigger losses, such as engine overheating damage. Regularly maintain the belt, inspect it every 50,000 kilometers to prevent abnormal noises.

As an enthusiast who frequently works on car repairs, when encountering abnormal noises from the right side of the engine, I first analyze the type of sound: a squealing noise indicates insufficient belt tension or wear; a humming noise points to a faulty alternator bearing; while a heavy grinding sound may suggest a failed water pump seal. The right side is specifically prone to these issues due to the concentrated placement of the alternator and water pump. Troubleshooting includes checking for belt cracks, using a wrench to test for pulley looseness, and examining bearing rotation for any sticking. Related factors such as unstable voltage can increase the alternator's load, indirectly causing noise. It's advisable to avoid high-speed driving to prevent accidents, while also lubricating bearings or replacing aged components. Leaving such issues unaddressed could escalate into chain failures, thereby increasing repair costs.

I haven't been driving for long, but suddenly there was an abnormal noise coming from the right side of the engine, which startled me. The most common causes are a loose belt or a damaged bearing: worn generator bearings produce a continuous humming sound, and water pump issues are also frequent, while belt slippage causes a squealing noise. Inspection method: start the engine to listen for the direction of the sound, and gently press components to check for looseness. If the abnormal noise worsens, don't drive; pull over and wait for a tow truck. Fixing it early saves worry and can prevent engine damage. Tip: Pay attention to belt tension during regular maintenance, replace if aged, to extend lifespan.

Every time I hear noise from the right side of the engine while driving, I get nervous, like the low humming sound last week. The cause might be an issue with the pulley system: the belt could be old and loose, making noise, or the internal bearings of the generator might be worn out. A faulty water pump can also often cause strange noises. Checking isn't difficult: open the engine hood, let the car idle, and locate the source of the sound. Safety first—take it to a professional repair shop immediately; don't delay. For regular maintenance, it's recommended to check the belt and bearing conditions every six months to prevent sudden noises.
