What could be causing my Vauxhall Movano to overheat?

I've noticed that my Vauxhall Movano has been overheating more frequently lately. What are some potential causes for this issue and what steps can I take to prevent it from happening?

Check the coolant levels and make sure they are not too low. If they are low, add more coolant and monitor the levels to see if they continue to drop.

Inspect the radiator for any clogs or damage. A clogged or damaged radiator can prevent proper cooling and cause your van to overheat.

Make sure the fan is working properly. If the fan is not functioning correctly, it will not be able to cool the engine and could contribute to overheating.

Check for any leaks in the cooling system. Even small leaks can cause a decrease in coolant levels and lead to overheating.

Consider installing a larger radiator or adding a secondary fan to improve cooling.
