Why Is My Car Making Whistling Noise When I Accelerate?

While there can be a number of sounds your car may produce abnormally such as whirring, rattling, squealing etc but every noise produced has its own set of reasons. Let us talk about the ones responsible for whistling:

1. Low Fuel Levels

When your car is running low on fuel you may encounter an unwanted whistle or two made by your car. It may be followed by ticking sound every time you accelerate or take a turn i.e. every time you put extra stress on the engine. Always make sure your car maintains at least a minimum amount of oil in it.

2. Faulty Pistons

Chances are you may be out of lubes without knowing it. It will result in a lack of smoothness while driving along with noisy and rough piston movement. Not only it will hamper the ride quality but also your mood! This may be the reason for your car making a whistling noise.

3. Cracked Hoses And Pipes

Hoses and pipes play a crucial role in an engine’s cooling system. But much to our dismay, they are one of the most delicate parts too. They are prone to wear and tear. Constant work may lead to small cracks on the hoses, it in turn not only invades air inside the vacuum but also breaks the seal. The passage of air is the culprit of the sound here.

4. Serpentine Belt Issues

If you hear weird noises from your car, a dysfunctional serpentine belt may be the issue. In addition to hoses and pipes, these belts play a critical role too and get damaged easily.

5. Improper Mating Of A Gasket Surface
