What to Do When the Car Makes Abnormal Noises During Startup?
3 Answers
When a car makes abnormal noises during startup, it is necessary to inspect multiple components of the car for troubleshooting. Below is relevant information on checking abnormal car noises: 1. Inspect the valve chamber: If the car has not been used for a while, the engine oil will return to the oil pan, causing the valve chamber to lack oil. Due to the absence of oil for sealing and lubrication, a hissing sound may be heard from the bottom of the car when it is first started, which is normal. 2. Check the engine belt: Try pinching the drive belt with your fingers and twisting it, ensuring the twist angle is below 90 degrees; if the engine belt is dirty and causes abnormal noises, cleaning it with water or applying some lubricant can eliminate the noise. 3. Inspect the engine mount bolts: Loose engine mount bolts can result in improper installation of the engine support. 4. Check the engine compartment: There might be foreign objects clogging the engine compartment.
When the car engine makes abnormal noises, I believe it's important to stay calm. First, listen to identify where the sound is coming from—is it from the front engine area or the chassis? A squealing noise usually indicates belt aging or bearing wear, so it's advisable to check the belt for cracks or tension. A clicking sound might point to ignition system issues or insufficient fluids. I recommend parking the car, opening the hood, and checking the oil dipstick level and coolant level, while also looking for dust or foreign objects stuck in the engine. If you can't handle it yourself, don't hesitate—take it to a professional repair shop for inspection. Safety first; don't push through with a noisy car. During regular maintenance, pay extra attention to engine components, and check the belt when changing the oil to prevent many issues. Remember one experience: my car made a rattling noise last week, and it turned out to be a loose fan—tightening it promptly solved the problem. In short, address small noises promptly to avoid bigger problems.
Hearing strange noises when starting the car? That might be the engine sounding an alarm. Let's analyze specifically: squeaking noises often indicate the belt needs adjustment or replacement, while clanking sounds may involve bearing or chain issues. I quickly check the engine oil and transmission fluid levels, topping them up if too low. Try cleaning the engine compartment dust with a damp cloth, as sometimes foreign object friction noises can be eliminated. Pay attention to sound changes while driving, maintaining low speed to avoid risks. If you know a bit, open it up to look, but don't disassemble randomly if you don't understand - drive to a repair shop immediately for diagnosis. Regular oil changes and avoiding rough roads can reduce abnormal noises. Simply put, don't ignore small noises - they're often precursors to major issues.
