How do I troubleshoot my Vauxhall Corsa's engine overheating issue?

My Vauxhall Corsa's engine has been randomly overheating, especially on long drives. What could be causing this and how do I fix it?

First, check your coolant levels and make sure they are at the recommended level. If they are low, it could indicate a leak somewhere in the system.

It could also be an issue with your water pump. If it's not functioning properly, it may not be circulating the coolant effectively.

Another possibility is a blocked or clogged radiator. If it's covered in debris or buildup, it can't cool the coolant effectively.

Lastly, it could be a problem with your thermostat. If it's stuck closed, it won't allow the coolant to flow properly, leading to overheating.
