Your engine is basically the heart of your car: if it's not working properly, you won't get very far. So when an engine noise comes up, it can feel like an emergency. But what kind of a sound does a dying car make? We've put together this list of common noises that indicate major problems brewing under the bonnet. If you hear any of these, pull over immediately and call for roadside assistance before something serious happens!
Rattling engine
A rattling engine is one of the most common types of noise you'll hear in your car. It can be caused by a number of things, including loose bolts or worn parts that need to be replaced. If this happens, it's important to get them checked out right away so you don't risk damaging other parts or causing an accident.
Knock sound
If you hear a knock sound, it's time to stop driving and call a mechanic. The problem could be in the engine or transmission of your car and should be addressed as soon as possible. The longer you wait, the more damage will occur and the more expensive it will be for you to fix your vehicle.
Whining noise from the engine
If you hear a whining noise from the engine, it could be caused by one of many things. First, check the engine mounts. You can do this by getting under your car and listening to where the noise is coming from when you rev the engine up. If it's coming from somewhere near where an engine mount would be located--between two parts of your car's frame--then that may be what's causing your problem. Next, check each belt in turn: timing belt (if applicable), water pump belt (if applicable), alternator belt (if applicable), power steering pump belt (if applicable). If any of these are loose or broken, they need replacing immediately!
Sputtering sound in the engine
If you hear a sputtering sound that seems to be coming from the engine, it could be caused by any of these problems:
The engine is misfiring. This means that one or more of the cylinders aren't firing properly and can cause damage to your vehicle's internal parts.
A cylinder is running on its own without any help from other cylinders (which can cause damage). It may also mean there's something wrong with one of your spark plugs or fuel injectors--or both!
Your ignition coil has failed and needs replacing ASAP before it causes further damage to other components in your car or truck's combustion system
Conclusion
If you hear any of these sounds coming from your engine, it's important to get it checked out as soon as possible - these engine noises need your immediate attention! The last thing you want is for your car to break down in the middle of nowhere because you didn't listen when something was wrong with it!
