Car Sounds and What the Issue Could Be

Cars can make a number of odd sounds when there is a problem. Unusual sounds should be taken seriously, as they could indicate potential mechanical damage. Depending on what noise you are hearing, it may be signaling issues with different car parts. Here, we offer insight into some commonly described abnormal sounds to be wary of and what they signify about your car's condition.

Squeaky Brakes

Squeaking brakes can be caused by a number of problems with parts in the braking system. This includes glazed brake pads or rotors and brake pads that are worn out. Lack of insulation in the brake pads can make the brakes start squeaking. Parts within the brakes can also wear out unevenly, which can also produce a squeaking noise.

Engine Rattling

Engines can make an assortment of odd sounds when they have problems. A rattling engine can be caused by a mixture of air and fuel in the engine cylinder that gets too hot, too quickly. This causes a premature ignition when the piston moves up on the compression stroke, producing a pinging or rattling sound.

Engine Clicking

Clicking is another strange sound an engine can make. An engine's ticking can be traced to several sources, including components that have come loose and low oil levels. If the oil level is low, the engine may also start to overheat. A reciprocating component can also cause engine ticking, including the valves, pistons, and connecting rods. A bad bearing attached to a rod can also cause clicking noises from the engine.

Knocking Under the Hood

Knocking sounds coming from under the hood can also be a problem with several sources. Knocking can be due to a problem with a component, such as a worn-out crankshaft. It can also be a sign of a transmission problem. The sound may also be described as a groaning, scraping, or rattling sound, indicating that a component is loose, too.

Engine Squealing

A squealing noise coming from the engine is often caused by a bad part. This includes a roller bearing that goes bad on an engine accessory, along with problems associated with the water pump or alternator. This sound means it's time to take the car to a mechanic.
