What could be causing the engine to overheat in my Vauxhall Astra?

I've noticed that my engine temperature gauge is running high and my coolant level seems to be going down quickly. What could be causing this issue and how can I fix it?

First of all, check your coolant levels regularly and make sure they are at the proper level. If the levels continue to drop, it could indicate a leak in the system. Also, check for any visible leaks under the car.

It's possible that the thermostat in your car is not functioning properly. This could cause your engine to overheat. It's best to take your car to a mechanic to have it checked and potentially replaced.

Another common cause of engine overheating in a Vauxhall Astra is a faulty water pump. If this is the case, it's important to have it replaced as soon as possible to prevent further damage to your engine.
