One common cause of engine overheating in a Vauxhall Astra is a malfunctioning thermostat. This can cause the engine to run too hot, leading to potential damage.

S

Another possible cause is a leak in the cooling system. If there is a coolant leak, the engine will not be able to cool properly and can lead to overheating.

E

A clogged or dirty radiator can also be a culprit. If the radiator is not functioning properly, heat cannot be dissipated from the engine and can cause it to overheat.

O

It's also important to check for any issues with the water pump or cooling fan. If either of these components is not working correctly, it can cause overheating.
