What are some common causes of engine overheating in a Vauxhall Astra?

I've noticed that my Vauxhall Astra's engine temperature has been consistently rising while driving. What could be causing this issue?

One common cause of engine overheating in a Vauxhall Astra is a malfunctioning thermostat. This can cause the engine to run too hot, leading to potential damage.

Another possible cause is a leak in the cooling system. If there is a coolant leak, the engine will not be able to cool properly and can lead to overheating.

A clogged or dirty radiator can also be a culprit. If the radiator is not functioning properly, heat cannot be dissipated from the engine and can cause it to overheat.

It's also important to check for any issues with the water pump or cooling fan. If either of these components is not working correctly, it can cause overheating.
