How to troubleshoot engine overheating in a Vauxhall Zafira Life?

I recently noticed that my Vauxhall Zafira Life's engine is overheating. How can I determine the cause of this issue and fix it?

First, check the coolant levels in the radiator and reservoir. If they are low, top them off and see if that solves the issue.

If the coolant levels are good, check for any leaks in the cooling system. Even a small leak can cause overheating.

Another possible cause of engine overheating is a faulty thermostat. This can be replaced by a mechanic or you can do it yourself with the proper tools.

If these steps don't solve the issue, it may be a more complex problem such as a malfunctioning water pump or radiator. It's best to have a professional diagnose and repair these issues.
