Why is my Vauxhall Astra overheating?

I've noticed that my Vauxhall Astra has been overheating more frequently lately. What could be causing this issue and how can I fix it?

It could be due to a malfunctioning thermostat. Have it checked and replaced if necessary.

Your coolant levels may be low. Top it up and see if that solves the issue.

Check for any leaks in the cooling system. If you notice any, have them repaired immediately.

It's possible that your radiator may be clogged. Flush it out or have a mechanic do it for you.

Make sure your radiator fan is functioning properly. If not, it may need to be replaced.

Have you recently had your oil changed? Old or dirty oil can lead to overheating. Have it changed if needed.

You may have a faulty water pump. Have it inspected and replaced if necessary.
