How to troubleshoot a faulty radiator in a Vauxhall Zafira Life?

The radiator in my Vauxhall Zafira Life seems to be not working properly. The car is overheating and there is a noticeable leak. What steps should I take to identify and fix the issue?

First, check the coolant level in your car and make sure it is at the proper level. If it is low, top it up and see if that solves the issue. If not, there could be a leak in the radiator or one of the hoses. Inspect the radiator and hoses for any visible cracks or holes.

If you don't see any visible issues, it could be a problem with the thermostat. A faulty thermostat can cause the car to overheat. Consider replacing it if it has not been changed recently.

If neither of these solutions work, it is best to take your car to a mechanic for a proper diagnosis. They will be able to use specialized tools to pinpoint the problem and give you an accurate solution.
