What could be the possible causes of my Vauxhall Astra's engine overheating?

I have a Vauxhall Astra and the engine seems to be overheating frequently. I have checked the coolant levels and they seem to be fine. What can be causing this issue and how can I fix it?

One possible cause of engine overheating could be a malfunctioning thermostat. It is responsible for regulating the flow of coolant through the engine and if it gets stuck, it can cause the engine to overheat. To fix this, you will need to get it replaced.

Another reason for overheating could be a leak in the cooling system. Even a small leak can impact the efficiency of the system and cause the engine to overheat. Check for any visible leaks and get them fixed as soon as possible.

Low coolant levels can also lead to engine overheating. Make sure to regularly check and top up the coolant levels. If you notice that the levels are frequently dropping, there might be a leak that needs to be fixed.
