How do I fix my Vauxhall Astra's overheating issue?

My Vauxhall Astra keeps overheating, especially during long drives. What could be causing this and how can I fix it?

First of all, make sure to check your coolant level regularly. If it's low, top it up with a 50/50 mix of coolant and water. Also, check for any leaks in the coolant system.

Another possible cause could be a faulty radiator or water pump. These should be checked and replaced if necessary.

If your Astra's engine is getting too hot, it could be a sign of a malfunctioning thermostat. Consider getting it replaced.
