What are some common issues with the Vauxhall Vivaro's cooling system?

I've noticed that my Vauxhall Vivaro's temperature gauge is running high. What could be causing this and how can I troubleshoot the issue?

Hi Sam, a common issue with Vauxhall Vivaros is a faulty thermostat. I recommend checking this first to see if it needs to be replaced.

Another possibility is a clogged radiator. Try flushing it out or having it professionally cleaned.

It's also important to check for any leaks in the cooling system. This could lead to overheating and other issues.
