How to prevent overheating in a Vauxhall Movano van?

I've been noticing that my Vauxhall Movano van has been running hotter than usual, especially during long drives. What could be causing this and how can I prevent it?

Make sure your radiator is clean and free of any debris. A buildup of dirt and grime can impede the cooling process and lead to overheating.

Check your coolant levels regularly. Low coolant levels can cause your van to overheat. If you notice that your coolant levels are consistently low, you may have a leak.

Consider upgrading your radiator to a larger or more efficient one. This can help improve the cooling process and prevent overheating.

Check your thermostat and make sure it is functioning properly. A faulty thermostat can cause your engine to overheat.

Make sure to change your oil regularly. Old or dirty oil can cause your engine to work harder, leading to overheating.
