What could be causing my Vauxhall Astra to overheat?

I've noticed that my Vauxhall Astra is overheating more often than usual. I've checked the coolant level and it seems to be okay. What could be the potential causes for this issue, and what steps should I take to address it?

One common cause of overheating in Vauxhall Astra's is a faulty thermostat. You may want to have it checked and replaced if necessary.

It's also possible that there is a leak in the cooling system. Check for any visible leaks and have them repaired as soon as possible.

Another potential cause could be a malfunctioning water pump. Have a mechanic inspect it and replace it if necessary.

Make sure to also check your radiator for any clogs or damage. A clogged or damaged radiator can cause overheating in your vehicle.
