What should I do if my Vauxhall Vivaro's engine keeps overheating?

I've noticed that my Vauxhall Vivaro's engine keeps overheating, even after I added more coolant. What could be causing this issue and how can I fix it?

There could be several reasons why your engine keeps overheating. It could be a faulty thermostat, a leak in the cooling system, or a clogged radiator. I recommend taking it to a certified mechanic to diagnose and fix the problem.

Another possible issue could be a malfunctioning water pump. This component is responsible for circulating coolant throughout the engine. Have a mechanic check the water pump and replace it if necessary.

In some cases, the overheating issue could be due to a faulty radiator cap. This component helps maintain the pressure in the cooling system and if it's not working properly, it can lead to overheating. Replace the radiator cap if needed.
