There are a lot of car noises that you’ll eventually learn to recognize. But some might sound a little strange initially, and you might not know what they mean. In this blog post, we’ll go over the different car noises you might hear and explain which ones you should ignore and which you should pay attention to. So whether you’re a seasoned driver or just starting, keep reading to learn more!

Although some noises may be alarming, many are not worth worrying about. Here are five different car sounds that you should not worry about.

1. A High-Pitched Whine When You First Start the Car: 

This noise is usually nothing to worry about and is likely caused by the starter motor engaging or disengaging. If the noise only happens when you start the car, then there is no need to worry. 

2. A Metallic Rattling Noise When You Are Driving: 

Suppose you hear a metallic rattling noise while driving. In that case, it is probably coming from a loose heat shield or exhaust system component. While the two engine components have an essential role to perform, it is not something worth halting your car in the middle of the road and calling for emergency help. 

3. A Hissing Sound When You Turn Off the Engine: 

A hissing sound after turning off the engine is likely due to pressure escaping from the radiator overflow tank as the engine cools down. This is an entirely normal occurrence and nothing to be concerned about. 

4. Clicking Noise When Turning: 

If you hear an unusual clicking noise when turning, it is likely due to low power steering fluid levels. Add power steering fluid to the reservoir under your car’s hood to fix this.  

5. Clicking or Popping Sounds

When your oil gets low, it doesn’t lubricate your engine parts as well as it should. The drop in oil levels causes engine parts to rub together, creating the clicking or popping noise you hear. 

Not keeping a watchful eye on engine oil levels and topping them off when necessary can eventually lead to big problems—like an exploded engine. So while a bit of clicking or popping might not seem like a big deal, you should take care of it right away by adding more oil to your car.

Car Sounds that Indicate Disaster and You Should Not Ignore

While some grumbling may be harmless, there are car sounds that suggest you should take your ride to the technician immediately.

1. A High-Pitched Squeal When Starting Your Engine 

This noise is often compared to the sound of a screaming animal, and for a good reason. It usually indicates that your serpentine belt is fraying and needs to be replaced. The serpentine belt is responsible for providing power to most of the engine accessories like the water pump, air conditioning compressor, and power steering. Drive to the nearest mechanic ASAP to avoid being stranded on the side of the road. 

2. Grinding Noise When You Start Driving 

If you hear grinding noise when you first start driving, it’s likely an indication that your clutch is wearing out. The clutch engages and disengages the engine from the transmission. When it’s working correctly, you shouldn’t hear any noise. The grinding noise is often caused by a damaged or misaligned pressure plate, throw-out bearing, or release fork. These components are integral to your clutch, so it’s best to take your car to a mechanic as soon as possible. 

3. A Knocking Noise Coming from Your Engine 

A loud, unusual knocking noise coming from under your hood is never a good sign. Several things could cause it, but it most likely indicates something is wrong with your pistons or connecting rods. If you continue driving without getting it checked out, the knocking could turn into banging, eventually leading to engine failure. Drive to a nearby mechanic or service station so they can look at it and determine what needs to be fixed.
