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

My Vauxhall Astra's engine has been overheating recently, especially during long drives. What could be causing this issue and how can I fix it?

It is possible that your engine's radiator is clogged or not functioning properly. This can lead to overheating, especially during long drives. I would suggest getting your radiator checked and cleaned if necessary.

Another possibility is that your thermostat is faulty and not regulating the engine's temperature properly. I would recommend getting it checked and replaced if necessary.

If your engine's coolant levels are low, it can also lead to overheating. Make sure to regularly check and top up your coolant levels.

If none of these solutions work, it could be an issue with your engine's fan or water pump. It's best to take your car to a mechanic for a professional diagnosis.
