Why does my Vauxhall Astra keep overheating?

I have a Vauxhall Astra that keeps overheating, even after I have changed the coolant and thermostat. What could be causing this issue?

Hi Evan, overheating can be caused due to a number of factors. One possible reason could be a faulty water pump. Another reason could be a blocked radiator or a leak in the cooling system. I recommend getting your Astra checked by a certified mechanic to identify the exact cause and get it fixed.

Hey Evan, have you checked the engine oil level? Low engine oil can cause overheating as it acts as a lubricant for the engine. If the level is low, top it up to the recommended level and see if it helps.

Hi Evan, another possible reason for overheating could be a faulty thermostat. You mentioned that you have already changed it, but it is possible that the new one is also not functioning properly. I suggest getting it checked by a professional mechanic to ensure it is working correctly.
