A fully operational and working machine is expected to produce some noise. The soft twirl of the motors or a soft hum of the engine should be enough to guarantee that the equipment is working properly. However, when you start hearing something out of the ordinary, it’s time to pay attention. There could be a number of reasons behind noises, and sometimes finding the cause can be difficult.
Following are some of the common vehicle noises that can spell trouble:
Whistling or Rumbling Exhaust Sounds
In most cars, the engine is located in the front but the exhaust of the engine travels the length of the car so noises can be created anywhere along that system through vibration or defect. The further back the sound is heard, the less serious the issue probably is. Apart from this, you might hear high-pitched or low-pitched whistling or rumbling sounds if it’s an exhaust issue. This could be caused by a crack or hole in the exhaust causing the exhaust to leak somewhere throughout the system.
Popping Engine Sounds
A popping sound coming from the tailpipe of your vehicle is a sign that there is something wrong with the engine. It could mean a clogged catalytic converter, a bad power circuit or accelerator pump in your carburetor, bad spark wires, worn or dirty spark plugs, water in your gasoline, a clogged fuel filter, an ignition problem, or a dirty air filter. Similarly, if there is a rattling noise when sitting at a stoplight or stop sign that sounds like a box of rocks shaking, then it could mean that your catalytic converter is bad. A popping sound that comes from the engine or under the hood could mean that a sensor might not be working properly or your car could benefit from a tune-up.
You will usually hear squeaking, squealing, or screeching noises when you have brake issues. And if there’s a clunking noise, it could indicate a problem with a worn steering system; brake hardware is missing or damaged or the disc brake caliper is mounted improperly. A squealing noise when braking could be various things; brake pads that have overheated and are now glazed, brake pads and/or shoes that are worn, dirt on the brake, disc brake calipers that have come loose, and more.
Pinging or Knocking Sounds
You may hear knocking or pinging. Although rare, it happens, and this generally means a problem with your fuel or ignition system. It could simply mean that your engine needs a tune-up or the fuel in your gas tank could contain water.
Gurgling noises are one of the stranger sounds when it comes to vehicles. Most of the time, you’ll hear this because your cooling system is not doing its job. Boiling coolant can be heard from the hoses as well as the coolant reservoir. In this case, let your engine cool and check the reservoir level to see if you need to add coolant.
