Why is my Vauxhall Crossland's temperature gauge fluctuating?

Recently I've noticed that the temperature gauge in my Vauxhall Crossland has been fluctuating between hot and cold. The engine doesn't seem to be overheating and there's no check engine light. What could be causing this and how can I fix it?

It could be a malfunctioning thermostat or a problem with the cooling system. I recommend taking it to a trusted mechanic and having them check it out.

Have you checked your coolant levels? If they're low, that could be causing the fluctuation. Make sure to top off your coolant and keep an eye on it.

I had a similar issue with my Vauxhall Crossland and it turned out to be a faulty temperature sensor. Get it checked and replaced if necessary.
