If your car makes a noise when you start it and then goes away as soon as you get on the road, it’s probably just a loose belt.
If you’re not sure what to do about it, take your vehicle to a mechanic or auto repair shop and they will be able to fix this problem for you.
If you want to try fixing it yourself, then you can check the belts and tensioners in your engine compartment.
You may need to replace them if they’re loose or damaged.
What is the cause?
The most common cause of a car that makes a noise when starting and then goes away is a timing belt problem.
The timing belt is responsible for controlling the rotation of your engine’s internal components, and if it slips or breaks, it can cause damage to those components.
The noise you hear when starting your car may be coming from the timing belt and it may just go away as the engine warms up.
You should take your car to an auto repair shop to have them check out your timing belt, and make sure everything is in working order.
Goes away when you drive it a few minutes
The check engine light goes away when you drive it for a few minutes because it is a self-diagnostic system, and the computer has already figured out what the problem is.
If you drive it around for a while, the car will reset itself to normal levels.
What can you do to check for these issues?
If the noise is coming from under the hood, check to see whether or not any of the belts are loose or frayed.
If they are, this could be causing the sound.
If the noise is coming from inside the car, check to see if any of your speakers are blown out or damaged in any way.
If so, they may need to be replaced before you can stop hearing that sound.
What kind of noise is it?
The kind of noise you’re talking about is likely a grinding or crunching that happens when the car first starts.
This can be caused by a number of things, but it’s most likely a problem with the starter.
If you have an older vehicle, there may be some age-related wear and tear that’s causing this issue.
You can also check to see if there’s any oil or water getting onto your engine while you’re starting it up if so, that could be contributing to the problems.
Low engine oil level
your engine may be low on oil. To check this, open your hood and check the dipstick.
If the level of oil is below the minimum mark, add some more until it reaches that mark.
Worn or damaged engine mounts or brackets
This is usually caused by one of the engine mounts, which are designed to absorb vibrations that occur during the normal operation of the vehicle.
If the mount is worn, it will not be able to absorb as much vibration, causing it to make more noise.
Conclusion
The noise is likely the engine valves adjusting. You may need to have your car serviced to make sure they’re working properly.
