Car Sounds and What the Issue Could Be

Owning a car is one of life's greatest achievements. The ability to maintain it is also another goal achieved. When a vehicle is serviced regularly, you will notice an increase in efficiency and durability. However, unusual sounds can occur, indicating the need for auto service. Here, we provide insight on the most common noises and what they might mean to your car.

Squeaky Brakes

Your car brakes will typically make squeaking sounds when it needs fixing. It might signify that the brake pads and rotors need some attention and possible replacements. You can decide to contact your mechanic to either replace the worn parts or correct the squeaky sounds by lubricating it.

Engine Rattling

Hearing rattling noises from the engine can be a result of premature ignition. Some would call it pre-detonation. The rattling noises coming from the engine can be contributed by several issues, including improper ignition timing, engine overheating, and incorrect fuel octane. The overall result is the incorrect mixing of fuel and air in the engine cylinder, causing an early ignition and may damage several parts like the valves, pistons, and the connecting rods.

Engine Clicking

The clicking noises coming from the engine can indicate that the oil levels are below what the engine requires to function properly. Checking the levels using a dipstick and replenishing the oil, if necessary, is a start on determining whether this is the problem. If the process doesn't solve the problem, consider seeking professional help to check on the upper side valve train.

Knocking Under the Hood

When you hear a knocking sound under the hood, immediate attention is needed. The knocking sound can result from multiple factors like the pistons, connecting rods, valves, and other components.

Engine Squealing

Various issues can cause a squealing engine. For the older vehicles, there is a need to check on worn accessory belts that operate significant components such as the power steering pump, A/C compressor, and the alternator. Squealing sounds can also emanate from the serpentine belt being worn down from friction, causing the squealing sounds.
