What causes the Vauxhall Insignia to overheat?

I have a Vauxhall Insignia and recently it has been overheating. I have checked the coolant levels and they seem to be fine. However, the temperature gauge keeps rising and the engine starts to make strange noises. What could be causing this issue?

There are a few possible causes for your car to overheat. It could be due to a faulty thermostat, a clogged radiator, or a damaged water pump. It is important to have your car inspected by a mechanic to determine the exact cause of the issue.

In some cases, a buildup of dirt and debris in the radiator can also cause overheating. You can try flushing out the radiator with a hose to remove any blockages. However, if the problem persists, it is best to take your car to a mechanic for further diagnosis.

Another possible cause could be a leaking head gasket. This can cause the engine to overheat and can be a serious issue if not addressed promptly. It is recommended to have your car inspected by a mechanic as soon as possible to avoid any further damage.
