5 Sounds You Don’t Want to Hear Your Car Make

Driving is a wonderful experience. You enjoy it a lot when covering hundreds of miles on expressways. It will be fun if you keep an eye on regular maintenance and address any issues that arise. Some of the car problems are easily identifiable. Others are signaled by unusual sounds. If you listen to unusual sounds, you should not ignore them. They may cause major repairing issues. When you start the engine, you must pay attention to some sounds that could indicate serious problems

What they might mean is another crucial point to consider. Some of the unusual sounds that you don’t want to hear your car make are the following:

Screeching or Squealing Brakes

A high-pitched screech or squeal, especially when applying the brakes isn’t good for your car. It may be caused due to varied reasons like worn brake pads, dust and debris, and sometimes moisture.

Born-out brake pads are the common reason for screeching brakes. They have a metal indicator that produces a squealing sound to alert you that it’s time to replace the worn-out brake pads.

Dust, dirt, and debris are other causes – caught between the brake pad and rotor. They can cause a temporary squeal. Driving through water or on a rainy day can cause squeal due to moisture. It goes away once the brakes heat up and the moisture evaporates.

Don’t ignore the brake pads as they can lead to reduced braking efficiency and eventually damage the rotors. They may lead to more costly repairs. You should pay attention to regular brake inspection and timely replacement. They are crucial for safe driving.

Knocking or Pinging from the Engine

A repetitive knocking or pinging sound coming from the engine, often more noticeable during acceleration may cause major issues, if not taken care of properly.

It may occur due to low-octane fuel, carbon buildup, incorrect ignition timing, or worn engine components.

Engine knocking can be caused due to the low-octane fuel that may rate lower than recommended.

Keep an eye on carbon deposits that can form on the internal parts of the engine. It may lead to knocking sounds. If the engine’s timing is off, it can cause knocking or pinging noises.

The worn-out or damaged parts like bearings can cause knocking sounds as they lose their ability to absorb the impact.

Never ignore the knocking sound due to the aforementioned reasons. If not taken care of properly, the knocking sound from the engine can lead to severe engine damage. Using the correct octane fuel is crucial. Paying attention to regular engine maintenance and timely tune-ups can prevent the issues.

Grinding Noise When You Shift Gears

If you listen to grinding noise when shifting gears (both manual and automatic transmission), you should visit the mechanic’s address instantly. It may be due to varied reasons like worn clutch in manual transmissions. A grinding sound at the time of shifting can indicate a worn clutch or clutch plate.

Grinding can signal problems with the transmission gears or synchronizers in both the manual and automatic transmissions.

Another noticeable point is keeping an eye on low transmission fluid. Always keep in mind that insufficient or dirty transmission fluid can cause grinding sounds as it fails to lubricate the moving parts properly.

Never ignore the noises when shifting. It can lead to complete transmission failure. Regular transmission fluid checks and servicing are crucial to keep your transmission in good working order.

Rattling or Clunking Under the Car

When you hear a rattling, clunking, or banging sound coming from beneath the car, especially when driving over bumps or uneven surfaces, you should consult with the mechanic. It may occur due to a loose exhaust system, worn suspension components, damaged heat shield, and damaged CV joints.

A damaged or loose exhaust system can cause rattling noises. The worn-out suspension parts (shocks, struts, or brushing) can also lead to clunking sounds.

A loose or damaged heat shield can cause a rattling noise. Keep an eye on the CV joints or Constant Velocity Joints that can wear out and cause clunking noises, when turning.

Visit the mechanic, if you hear such sounds. If not taken care of properly, they may lead to further damage and unsafe driving conditions. You must focus on regular inspections and timely repairs of the suspension and exhaust system. They are crucial for smooth and safe driving.

Hissing or Sizzling from the Engine

When you listen to a hissing or sizzling noise coming from the engine area, you should consult the mechanic immediately. It is noticeable when the engine is running or immediately after it’s turned off. It may occur due to varied reasons like a coolant leak due to a damaged hose, radiator, or water pump. Overheating is another issue behind such hissing or sizzling sound from the engine. If the engine is overheating, it can cause hissing sounds as the coolant escapes from the radiator cap or reservoir.

A vacuum leak is another cause behind the hissing or sizzling sound from the engine. You should not ignore such sounds as it can indicate serious issues like coolant leaks or engine overheating. It can lead to engine damage, if not addressed promptly. Regularly checking the coolant level and inspecting for leaks can help prevent overheating problems.

What Are the Preventing Measures to Avoid Encountering These Troublesome Sounds?

Regular car maintenance is essential to avoid encountering these troublesome sounds and the issues. You must schedule routine inspections with a qualified mechanic to find out the potential problems.

• Fluid checks will be another crucial step. You should regularly check and top off all fluids like coolant, brake fluid, transmission fluid, and engine oil.
• Brake inspection is equally important with proper servicing to ensure they are in good working conditions.
• Engine tune-ups are another crucial point to consider – mainly keeping the engine running efficiently.
• Not to mention the suspension and exhaust system checks for any signs of wear/damage.
• If the belt is loose, you must ask the mechanic to adjust the tensioner pulley. If it is worn, ask the mechanic to replace it with a new one. If the belts show significant wear, you should consider replacing all belts.
• Don’t forget to identify the parts with the worn bearing like the alternator, water pump, and others. If required, replace the bearing or the entire component.
• You can patch the small holes with exhaust tape or epoxy. Replacing the damaged sections of the exhaust system will be a convenient way if the hole is big.

If the internal engine parts are causing noise, you must visit the repairing center for the adjust valve clearances, replace timing chains/belts, or address piston slap by inspecting and possibly replacing pistons and rings.
