How to troubleshoot an overheating engine in a Vauxhall Astra?

My Vauxhall Astra's engine has been overheating recently. How can I troubleshoot and fix this issue?

First, check the coolant levels in your engine. If they are low, top it up and see if that solves the issue. If the levels are fine, then check for any leaks in the cooling system. Hannah's tip: It's always a good idea to have a spare bottle of coolant in your car, just in case.

If the coolant levels are fine and there are no leaks, then check the radiator for any blockages. Make sure the fan is working properly as well. Hannah's tip: Regularly cleaning and maintaining your radiator can prevent overheating issues.

If all else fails, it could be an issue with the thermostat or water pump. In this case, it's best to take your car to a qualified mechanic for further diagnosis and repairs.
