Car Sounds and What the Issue Could Be

One of the first indicators that your vehicle may need some servicing is when unusual sounds occur. These noises may come from several parts of your car. If you find that your vehicle is making strange sounds, the below guidelines will help you identify the sounds and their significance.

Squeaky Brakes

Brakes will eventually need some adjustments and servicing to help them stay in good condition.If you detect a squeaking sound coming from the brakes, then this is a good indication that the brake pads are worn. A service expert can determine the right repairs for this sound. They may decide to lubricate the brake components or replace them entirely.

Engine Rattling

Rattling sounds that originate from your engine is as a result of premature ignition or pre-detonation. This type of problem can be caused by several issues, including improper fuel octane, incorrect ignition timing, and engine overheating. This noise is the improper mixing of fuel and air in the engine cylinder, causing an early ignition and possible damage to other parts like the valves, connecting rods, and the pistons.

Engine Clicking

The clicking noises that come from the engine may indicate that the oil levels are low. You can check the oil level using the dipstick. If the clicking sound is persistent, even after adding the oil, your vehicle might have a faulty upper valve train.

Knocking Under the Hood

When hearing a knocking sound emanating from beneath the hood, seek professional service immediately. The noise may be an indication of a more significant issue relating to valves, pistons, connecting rods, and other components.

Engine Squealing

There are many issues that can cause engine squealing. For older vehicles, a worn accessory belt can be the source of the sound. For new vehicles, the problem is likely to emanate from the serpentine belt being worn down, too loose or too tight.
