How to fix the overheating issue in my Vauxhall Insignia?

I've been experiencing an overheating issue in my Vauxhall Insignia. The temperature gauge is constantly on the high end and the engine seems to be struggling. What could be the cause of this and how can I fix it?

First and foremost, it's important to check the coolant levels in your car. If they are too low, top them up and see if the overheating issue persists. If it does, it could be a sign of a leak in the cooling system. In this case, I would recommend taking your car to a mechanic for a thorough inspection.

Another potential cause for overheating could be a faulty thermostat. This component regulates the flow of coolant in your engine and if it's not working properly, it can lead to overheating. It's best to get this checked and replaced if necessary.

In some cases, a clogged radiator can also result in overheating. Dirt and debris can build up over time, hindering the proper flow of coolant. Regularly flushing out your radiator can prevent this issue from occurring.
