What Should I Check When My Vauxhall Astra Overheats?

My Vauxhall Astra has been overheating recently, what are the potential causes and what should I do?

Firstly, check the coolant level and make sure it's at the recommended level. If it's low, top it up and monitor the level over the next few days to see if it's dropping. If it is, there is likely a leak in the system that needs to be addressed.

Next, check the radiator for any visible damage or leakage. If there is, it will need to be repaired or replaced.

If the coolant level and radiator are fine, it could be an issue with the thermostat or water pump. These components can wear out over time and may need to be replaced.

Lastly, if none of these seem to be the issue, it's possible that the engine itself is overheating. This could be due to a faulty temperature sensor or a problem with the cooling system. It's best to take your car to a mechanic for a proper diagnosis.
