How do I fix a leaking coolant in my Vauxhall Astra?

I noticed a puddle of green liquid under my Vauxhall Astra. Upon inspection, I realized it was leaking coolant. How can I fix this issue?

First, check to see if the coolant reservoir is low. If it is, top it off with the same type of coolant as your car already has. If the reservoir is full, then the leak may be coming from a hose or the radiator. Check for visible cracks or holes and replace any damaged parts.

If you can't find any visible leaks, the issue may be a blown head gasket. This is a more serious problem and will require professional help to fix. It's important to get this fixed immediately as driving with a blown head gasket can cause serious engine damage.

In the meantime, you can try using a stop leak product to temporarily fix the leak. These products work by sealing small leaks in the cooling system. However, keep in mind that this is just a temporary fix and you should still get the issue properly fixed.
