How to troubleshoot a common problem with the Ford Kuga engine?

I've noticed that my Ford Kuga's engine has been making strange noises. How can I troubleshoot this issue?

First, make sure to check the engine oil level. Low oil can cause engine noise. If the oil level is fine, then the noise may be due to a faulty engine belt. Have a mechanic inspect and replace it if necessary.

Another potential problem could be with the fuel filter. Try replacing it and see if the noise goes away. If not, it could be a more serious issue with the engine such as a failing cylinder.

It's always a good idea to regularly check and replace the spark plugs as well. Worn out spark plugs can cause engine noise and affect the overall performance of your Ford Kuga.
