How to properly maintain the Vauxhall Corsa's engine?

I've been experiencing some issues with my Vauxhall Corsa's engine and I'm not sure how to properly maintain it. Can someone give me some advice on what I should be doing to keep my engine running smoothly?

Regular oil changes are key to maintaining your engine's health. Make sure to follow your vehicle's recommended maintenance schedule and use high quality oil.

In addition to oil changes, it's important to check and replace your air filter regularly. A clogged air filter can significantly reduce your engine's efficiency.

Another important aspect of engine maintenance is monitoring your coolant levels and regularly flushing and replacing the coolant when necessary.
