How to troubleshoot a noisy engine in my Kia Picanto?

My Kia Picanto has been making strange noises when I start the engine. What could be the issue and how can I fix it?

The most common cause of a noisy engine in a Kia Picanto is a faulty belt tensioner. It is recommended to have it checked and replaced if necessary.

Another possible cause could be a worn out serpentine belt. Make sure to have it inspected and replaced if needed.

It could also be due to low engine oil levels or dirty oil. Check the oil level and quality and change it if necessary.

If the noise is a high-pitched squeal, it could be an issue with the alternator. Have it checked and replaced if needed.

It is recommended to have a certified mechanic diagnose and fix the issue to avoid further damage to your engine.
