Why is my Vauxhall Zafira Life always overheating?

I purchased a used Vauxhall Zafira Life a few months ago and recently I've noticed that the temperature gauge is always close to the red zone. I've checked the coolant level and it seems fine. What could be causing this issue?

It could be a problem with your radiator fan. If it's not working properly, it won't be able to cool down the engine, causing it to overheat.

Another possibility could be a faulty thermostat. If it's stuck in the closed position, it won't allow coolant to flow through the engine, leading to overheating.

Check for any leaks in the cooling system. Even a small leak can cause your engine to overheat. Also, make sure the radiator is not clogged with dirt or debris.
