What causes the engine to overheat in a Vauxhall Astra?

I've noticed that my Vauxhall Astra's engine seems to be overheating more frequently. What could be causing this issue and how can I fix it?

One common cause of engine overheating in a Vauxhall Astra is a faulty radiator or radiator fan. It's important to regularly check and maintain these components to prevent overheating.

Another potential cause could be a leak in the cooling system. Be sure to check for any leaks and have them repaired as soon as possible to avoid further damage to the engine.

In some cases, a malfunctioning thermostat can also cause engine overheating. If you notice changes in your vehicle's temperature gauge, it's best to have the thermostat checked and replaced if necessary.
