Why is my Vauxhall Astra's engine temperature higher than normal?

I've noticed that my Vauxhall Astra's engine temperature has been consistently higher than usual. I'm not sure if this is a cause for concern or if it's just due to the summer heat. What could be causing this issue?

It's possible that your thermostat is stuck open, causing the engine to not heat up properly. It's also possible that you may have a coolant leak, so I would suggest checking your coolant level and inspecting the hoses for any potential leaks.

Another potential issue could be a faulty water pump. If the water pump is not working properly, it won't be able to circulate coolant through the engine, resulting in higher engine temperatures. I would recommend getting your water pump checked by a mechanic.

It's also important to regularly check your oil levels. Low oil levels can also cause overheating as the oil helps to regulate engine temperature. If your oil levels are low, make sure to top it up to the recommended level.
