What is causing my Vauxhall Zafira Life to overheat?

I have been having issues with my Vauxhall Zafira Life overheating on long drives. I have already checked the coolant levels and they are fine. What could be causing this issue and how can I fix it?

It could be a problem with the radiator fans not working properly. You may need to have them checked and replaced if necessary. Also, make sure to check for any leaks in the cooling system.

Another possible cause could be a faulty thermostat. If it's not opening and closing properly, it could cause the engine to overheat. Have it checked and replaced if needed.

Make sure to also check the condition of your water pump. If it's not working properly, it can't circulate coolant through the engine, leading to overheating. Have it checked and replaced if necessary.
