How to resolve low engine temperature in a Vauxhall Insignia?

I have a Vauxhall Insignia and recently noticed that my engine temperature is lower than usual. Is this a cause for concern? How can I fix this issue?

It is normal for the engine temperature to fluctuate, but if it consistently stays at a low level, it could be a sign of a faulty thermostat. It is best to get it checked by a mechanic.

Check the coolant levels and make sure they are at the recommended level. Low coolant can also cause low engine temperature.

Another possible cause could be a malfunctioning temperature sensor. It is recommended to get it diagnosed and replaced if necessary.
