Whining noises from children are bad enough, but when your car is whining it's a sign that something is wrong and needs attention. The last thing you want is to wait too long until the sound becomes more serious, so it's important to know what to look out for and what solutions are available.
One of the first things you should do when you hear a whining noise is to check the level of your oil, power steering fluid and transmission fluid. Many whining sounds can be caused by a loss of fluid, which can often be easily fixed with a quick top-up or replacement. Keeping your vehicle's fluid levels at the recommended level will reduce friction and resistance and keep your engine running smoothly.
A serpentine belt loops around multiple gears and pulleys on your vehicle's engine to ensure everything is working in tandem at the correct rotational speed. If the belt is loose or worn down, it can cause a whining sound when your engine is under load and may require a repair or replacement.
A common cause of whining noise is a leak from one of your vehicle's components, such as the power steering fluid pump, transmission fluid pan or engine oil drain plug. If you have a leak, it's important to have it repaired immediately to avoid further damage and a costly repair bill.
